China's Wafer Fab Equipment Industry Present & Future
Covering the present tools & future roadmap of NAURA, AMEC, ACM Research, SiCarrier and Piotech
The advent of LLMs and the intensification of the US-China rivalry have placed semiconductors at the undisputed center of global power dynamics. While headlines frequently focus on the progress of Chinese chip designers like Huawei and foundries such as SMIC and CXMT, a critical yet far more opaque segment of the supply chain remains largely in the shadows: the domestic Wafer Fab Equipment (WFE) sector. It is these complex machines that will ultimately determine the success or failure of Beijing’s chip ambitions. Historically reliant on foreign technology, China is now driven by a national mandate for self-sufficiency and is pouring immense resources into cultivating its own domestic WFE ecosystem.
Key Chinese semiconductor equipment manufacturers AMEC, Naura, ACM Research, Piotech, and SiCarrier are rapidly advancing their product roadmaps and launching new etching, deposition, cleaning, and metrology tools. Their main focus is on achieving greater technological self-sufficiency, expanding into advanced process nodes, and increasing global competitiveness. They still face significant challenges in matching the breadth and depth of established global leaders. Their strategies involve significant investment in research and development, and aggressive expansion of product portfolios. While they have made notable progress in areas like etching, deposition, and cleaning, they continue to face intense competition from established global giants who dominate the market.
AMEC (Advanced Micro-Fabrication Equipment Inc. China)
Founding & Early Years
AMEC was founded on May 31, 2004, by Dr. Gerald Yin, who previously held senior management positions at Applied Materials. The company started with a vision to become a leading global supplier of high-end semiconductor processing equipment. A significant early milestone was the development of China’s first domestically produced dielectric etch system. This achievement marked a crucial step in China’s efforts to build a self-reliant semiconductor equipment industry. In its initial years, AMEC focused on developing and refining its core etching technologies. By 2007, the company had successfully developed and shipped its first etching and thin film equipment to a domestic customer. Strategic financing rounds, including a $38 million Series A funding in 2005 and a $58 million Series C funding in 2008, enabled it to accelerate R&D and market entry. By 2008, AMEC had several of its Primo Etch™ dielectric plasma etching systems and Primo HPCVD™ systems undergoing trials at major Asian chip manufacturing plants.
A key turning point was the resolution of intellectual property disputes with Applied Materials around 2010, which allowed AMEC to focus on its growth trajectory. The company’s Primo D-RIE™ (Dual Frequency Reactive Ion Etch) system, launched in the late 2000s, gained significant traction for its innovative design, high productivity, and cost-effectiveness, winning industry awards and being adopted by numerous customers for 65/45/32nm and more advanced chip manufacturing. A major corporate milestone was its listing on the Shanghai Stock Exchange’s STAR Market in July 2019. Over the years, AMEC has grown from a small startup to a global enterprise with over 2,000 employees and more than 5,000 reaction chambers installed and running in over 130 production lines worldwide by 2024.
The company has rapidly grown to become a key player in the global semiconductor equipment industry, particularly recognized for its advancements in plasma etching and Metal Organic Chemical Vapor Deposition (MOCVD) technologies. AMEC’s mission is to provide leading-edge processing equipment and process technology solutions to global integrated circuit (IC) and LED chip manufacturers, thereby assisting clients in enhancing their technological capabilities, boosting productivity, and reducing manufacturing costs. The company’s strategic focus revolves around organic growth through intensive research and development, complemented by selective investments and collaborations, rather than relying heavily on mergers and acquisitions. AMEC has strategically expanded its operations beyond mainland China to establish a significant global footprint. The company’s headquarters are located in Shanghai, China, which serves as its primary hub for research, development, and manufacturing. To support its global customer base, AMEC has established regional subsidiaries and service centers in key international locations. These include AMEC Japan Co., Inc. in Japan, AMEC North America, Inc. in the United States, and Advanced Micro-Fabrication Equipment Korea Ltd. in South Korea. Additionally, the company operates Advanced Micro-Fabrication Equipment International Pte. Ltd. in Singapore, which handles trade sales. This network of international subsidiaries enables AMEC to provide comprehensive, seamless support to its customers worldwide, covering aspects from system preparation and start-up to process integration, sign-off, warranty, and post-warranty services.
AMEC’s leadership has articulated a clear vision for the future, targeting an expansion of their product coverage from the current 30% to 60% of high-end integrated circuit equipment within the next five to ten years. This ambitious goal encompasses not only their core strengths in etching and thin-film deposition but also extends to metrology and inspection tools, as well as certain wet processing equipment, positioning AMEC as an emerging platform-based equipment provider. The company is also reportedly exploring pathways to achieve 5nm process nodes without relying on EUV (Extreme Ultraviolet) lithography, with the help of their ultra-precise etching tools.
In 2022, AMEC reported a total revenue of approximately 4.74 billion RMB. This figure saw a substantial increase in 2023, reaching 6.26 billion RMB. The growth momentum continued into 2024, with the company achieving a remarkable revenue of approximately 9.07 billion RMB. This represents a year-over-year growth of approximately 44.73% from 2023 to 2024. The primary driver for this revenue surge in 2024 was the significant increase in sales of its etching equipment, which contributed approximately 7.28 billion RMB, marking a 54.72% increase compared to the previous year. While MOCVD equipment sales experienced a slight decline of about 18.03% to 379 million RMB in 2024, the company successfully introduced its LPCVD equipment to the market, generating sales of approximately 156 million RMB in its first year.
A cornerstone of AMEC’s strategy is the aggressive development of thin-film deposition equipment, which is projected to grow significantly, potentially reaching half the scale of their established etching equipment business within three to five years. This expansion is critical as thin-film processes are integral to advanced semiconductor manufacturing, especially with the transition to 3D device architectures and sub-10nm technology nodes, where the complexity and number of deposition steps are increasing. The company is actively working on approximately 40 different types of thin-film deposition equipment, with a notable emphasis on addressing market gaps created by international export restrictions. Specifically, AMEC plans to complete the development of over 20 types of such embargoed thin film equipment to cover all advanced metal applications by 2029. Recent successes in this area include the rapid market adoption of their LPCVD (Low-Pressure Chemical Vapor Deposition) and ALD (Atomic Layer Deposition) tungsten metal deposition systems. For instance, after shipping only one unit in 2023, AMEC delivered 128 units in 2024, with expectations of further substantial growth in 2025. This rapid scaling underscores both the market demand and AMEC’s manufacturing and support capabilities. The company’s LPCVD and ALD equipment, particularly for metal tungsten applications, have seen rapid market adoption, with LPCVD equipment shipments exceeding 150 reaction chambers within a year of market validation and securing substantial orders (approximately 476 million RMB in 2024).
Etching
The company has developed three generations and 18 models of etching machines over the past two decades, with an accelerating pace of product development. Nearly 4,000 Capacitively Coupled Plasma (CCP) etching reaction chambers are operating in logic production lines globally. As of 2024, AMEC had over 270 CCP etching reaction chambers operating in 5nm and below production lines globally. In 2024 alone, over 1,200 CCP etching reaction chambers were produced and shipped. The company is also heavily investing in its ICP etching technology, with the Nanova LUX series (Nanova LUX-WT, Nanova LUX-Cryo) already in production or customer validation, and the next-generation Primo Nanova 2G under development in the lab. These ICP etchers are crucial for applications in advanced logic, power devices, Micro-LEDs, and specialized structures like metalenses for AR/VR. A key technological differentiator for AMEC is its “dual reaction chamber” design, which offers high throughput and lower processing costs while maintaining exceptional precision. The ICP dual-chamber system, Primo Twin-Star®, achieves an etching precision of 0.2 Å/min (0.02 nm), equivalent to one-tenth the diameter of a silicon atom, and has shown minimal deviation between chambers in rigorous testing. This level of precision is critical for advanced nodes. Furthermore, AMEC is developing specialized etching solutions for challenging applications, such as ultra-high aspect ratio (UHAR) etching for 3D NAND and DRAM manufacturing. Their UHAR CCP etchers, designed for aspect ratios of 60:1 or higher, and UHAR ICP etchers for mask etching at aspect ratios of 40:1 or higher, have been successfully verified and are entering mass production. The company is also reportedly developing even more advanced 90:1 high aspect ratio etchers, which could contribute to revenue from late 2025 or 2026 (YMTC 3D NAND). Recent product launches include the Primo Twin-Star, an etching system with sub-angstrom precision (0.2Å), and the Primo Halona, a 12-inch wafer edge etching device, both designed for 5nm and below processes
Beyond core etching and thin-film deposition, AMEC is strategically expanding into other critical equipment segments. The company has been investing in metrology and inspection, particularly electron beam inspection, for seven to eight years, recognizing its importance for advanced process development and as a domestic shortcoming. Instead of acquiring existing players, AMEC has chosen to build its own team with top global experts. This aligns with their philosophy of building core technological expertise internally. The company’s R&D efforts are extensive, with over 20 new equipment types across six major categories currently in development. These include next-generation CCP and ICP etchers, bevel etchers, LPCVD and ALD film equipment, silicon and silicon-germanium epitaxial (EPI) growth systems, PECVD (Plasma-Enhanced Chemical Vapor Deposition) equipment with new plasma sources, and the aforementioned electron beam inspection tools. Newly developed silicon/germanium-silicon EPI and bevel etching equipment are also slated for market verification in the near term. This broad R&D portfolio indicates a clear roadmap towards becoming a more comprehensive equipment supplier.
MOCVD
AMEC’s MOCVD equipment, particularly for gallium nitride (GaN)-based LED production, has already achieved global leadership, holding over 80% of the market share for GaN-based LED lighting equipment. In the MOCVD market, AMEC’s Prismo series, particularly the Prismo A7™, has established a dominant position. The company celebrated the shipment of its 100th Prismo A7 reaction chamber in May 2025. The company continues to innovate in this space, with the Prismo UniMax® MOCVD system for Mini-LED applications gaining significant traction since its launch in June 2021, recognized for its high yield, uniformity, and throughput. The Prismo HiT3 for deep UV LEDs and Prismo PD5 for GaN power devices have also secured repeat orders from clients, indicating successful market entry and validation. AMEC is also actively developing MOCVD solutions for emerging applications. This includes equipment for silicon carbide (SiC) power devices (currently in production verification), GaN Micro-LED blue/green light equipment( approved and entered production), and GaN power device epitaxy equipment, along with gallium arsenide (GaAs) red/yellow light equipment both expected to enter production within the year. Furthermore, MOCVD equipment for Micro-LED high-end displays is progressing well, with laboratory results showing excellent wavelength uniformity. A prototype has been shipped to a leading domestic customer for production verification. This diversification within the MOCVD segment highlights AMEC’s strategy to leverage its core technology across multiple high-growth areas in the compound semiconductor and display markets.
The company’s commitment to R&D is substantial, with investment increasing by 94.3% in 2024 to reach RMB 2.45 billion, accounting for approximately 27% of its revenue, a notable rise from 20.15% in 2023 and 19.59% in 2022. The 94.13% year-on-year increase in R&D spending in 2024 compared to 2023 further highlights this aggressive ramp-up. This high level of investment has significantly shortened new product development cycles from 3-5 years to about two years or even less. To support this growth and expansion, AMEC is also scaling its manufacturing infrastructure, with new production and R&D bases, such as the one in Lingang, Shanghai, significantly increasing its operational footprint. A new R&D and production base in Chengdu, with an investment of approximately 3.05 billion RMB, is planned for the 2025-2030 period, focusing on CVD & ALD, E-Beam inspection tool, and other critical equipment for advanced logic and memory chips. The company is focused on achieving even higher precision, better critical dimension control, and improved selectivity for complex 3D device architectures like Gate-All-Around (GAA) transistors and increasingly dense 3D NAND structures. The development of the Primo Nanova 2G ICP etcher is a step in this direction, aiming to provide enhanced capabilities for advanced logic and specialty device manufacturing. They have 2,941 patent applications filed by March 2025, 83% of which are invention patents. AMEC plans to apply for at least 300 patents globally in 2025. The company’s long-term vision extends to 2035, by which it aims to become a globally first-tier semiconductor equipment company in terms of scale, product portfolio, competitiveness, and customer satisfaction. As AMEC continues to innovate and expand its product portfolio, it is likely to capture a larger share of the global WFE market, particularly in its core strengths of etching and MOCVD, and increasingly in deposition.

ACM Research (ACM Research, Inc.)
ACM Research Shanghai’s origins are closely tied to its parent company, ACM Research, Inc., which was founded in 1998 by Dr. David H. Wang (Hui Wang) in Fremont, California. Dr. Wang is credited with the development of stress-free copper polishing technology, which was the initial focus of ACM Research. However, this initial strategy did not yield significant commercial success. Recognizing the growing importance of the Chinese semiconductor market and the potential for local development and manufacturing. Dr. Wang established ACM Research (Shanghai), Inc. on May 17, 2005. This move was part of a strategic initiative, often referred to as a “second startup”, to specifically target the semiconductor wet process equipment market from a base in China. The establishment of ACM Shanghai was significantly influenced by Shanghai’s burgeoning semiconductor industry and the support from local government initiatives aimed at fostering high-tech enterprises. The Shanghai subsidiary set up operations in the Zhangjiang High-Tech Park, a hub for semiconductor and technology companies in Shanghai. The company demonstrated resilience and strategic agility by pivoting its focus towards the wafer cleaning segment, introducing its first product based on this new direction in 2001, which was sold to leading-edge wafer manufacturers in the United States.
A prominent supplier of wafer and panel processing solutions for semiconductor and advanced packaging applications. The company has strategically positioned itself for growth by adopting a “platformization” and “internationalization” strategy, aiming to diversify its product offerings and expand its market reach globally. Originally known for its cleaning equipment, the company has successfully broadened its portfolio to include other critical semiconductor manufacturing tools, thereby significantly increasing its addressable market. This expansion is evident in its financial performance, where in 2023, semiconductor cleaning equipment accounted for $404 million in revenue, while other equipment such as electroplating, vertical furnaces, and stress-free copper polishing contributed $103 million in revenue, and advanced packaging solutions brought in $50.516 million. This diversification demonstrates the success of its platform-based approach. The company is actively developing and launching new products, with a focus on increasing the domestic supply of equipment in areas with low localization rates in China, such as PECVD (Plasma-Enhanced Chemical Vapor Deposition) and Track (coater/developer) systems.
ACM Research is a dominant domestic supplier of wet processing equipment. The company is recognized as the largest and most comprehensive semiconductor cleaning equipment enterprise in China in terms of market share and product range, reportedly holding around 23% of the Chinese semiconductor cleaning equipment market. In the last three years, ACM Research has seen significant traction with several of its newer product lines and has launched several key products. The company’s ECP (Electro-Chemical Plating) and furnace equipment collectively surpassed $100 million in revenue in 2023, marking a milestone in its product expansion efforts. The Ultra ECP ap-p tool, designed for fan-out panel-level packaging (FOPLP), won the 2025 3D InCites Award in the Technology Enablement category, recognized for its innovation in high-volume copper deposition for large panels (supporting 515mm x 510mm and 600mm x 600mm panel sizes) using a horizontal plating approach. Its panel-level advanced packaging technology can be applied to micron-level high-density packaging, especially suitable for AI GPU packaging and high-density HBM. ACM also launched its Track and PECVD tools in late 2022, effectively doubling its serviceable available market. The company’s UltraC vac-p (negative pressure cleaning) and UltraC bev-p (panel edge etching/cleaning) were launched for advanced packaging FOPLP applications. The Ultra Pmax™ PECVD and Ultra Lith track coater/developer ArF products were launched in late 2022. The Ultra fn Furnace was ACM’s first dry processing tool, introduced in 2020. The UltraC Tahoe cleaning system achieved a major performance breakthrough in 2024, reducing chemical consumption by up to 75%. According to ACM’s estimates, sulfuric acid reduction alone can save up to $500,000 per tool per year, and the treatment of sulfuric acid waste can further reduce costs and be more environmentally friendly. A plasma-enhanced atomic layer deposition (PEALD) furnace successfully entered two Chinese IC wafer fabs for optimization. The company's Ultra ECP map is used for front-end wafer fabrication copper interconnect applications.

Founded relatively recently (around 2021-2022), the company made a striking debut at SEMICON China 2025 by unveiling an extensive range of 31 new products across six major categories, signaling its intent to become a major domestic supplier and eventually a global competitor. SiCarrier’s product lines cover critical areas of semiconductor manufacturing, including etching, thin-film deposition (PVD, CVD, ALD, EPI), and, most notably, a wide array of metrology and inspection equipment. The company’s future roadmap is characterized by a strong push towards developing equipment for the most advanced process nodes, including aspirations in EUV lithography, and a focus on achieving a high degree of self-sufficiency in core technologies and components. This rapid rise and ambitious strategy position SiCarrier as a potentially disruptive force in the global semiconductor equipment landscape. The company has strong state backing and connections to Huawei’s technological ecosystem.
In its initial product launch phase around March 2025, SiCarrier introduced a remarkably broad suite of equipment, all named after famous Chinese mountains, underscoring its comprehensive approach. Etching Equipment, Wuyi Mountain Series, is designed to support advanced logic and memory chip manufacturing. SiCarrier claims these etchers utilize RF/plasma field technology that offers a 10x improvement in energy control precision and hardware response times reduced from 10ms to 1ms, supporting progression to more advanced nodes. The Thin-Film Deposition portfolio is extensive, featuring: EPI equipment under the Emei Mountain Series, targeting applications like third-generation semiconductors (SiC, GaN). ALD equipment, Ali Mountain Series, with products like PEALD and Metal ALD aimed at high-conformality dielectric films and high-aspect-ratio metal gate ALD, reportedly supporting processes down to 5nm and below, including GAAFET structures. CVD equipment, Changbai Mountain Series, including PECVD and Metal CVD for dielectric and selective metal film deposition, also supporting future advanced nodes. PVD equipment, Putuo Mountain Series, with models for metal planar film deposition, mid-process metal contact/hardmask layers, and back-end metal interconnect layers, suitable for 12-inch wafers with high positioning accuracy. SiCarrier has already developed lithography machines capable of processing 300mm wafers for 28nm and older process nodes using DUV technology.
A particularly significant and diverse offering from SiCarrier is in the Metrology and Inspection Equipment category. The BFI (Bright Field patterned Wafer Inspection), Yuelu Mountain Series, utilizes a deep UV broadband plasma light source, large NA objectives, and high-speed detectors for high sensitivity and throughput.

The proceeds will mostly go towards R&D, and Chinese state-owned firms, state funds, as well as domestic venture capital and private equity funds have expressed interest in investing, said two sources. This unit does not include SiCarrier's lithography assets (crown jewel).
Lithography Equipment (EUV Aspirations)
The lithography equipment segment is one of the most critical and technologically challenging areas in semiconductor manufacturing, currently dominated by a few global players, most notably ASML from the Netherlands, which holds a near-monopoly on EUV (Extreme Ultraviolet) lithography systems essential for advanced nodes below 7nm. Chinese companies are actively working to develop domestic capabilities in lithography, particularly for DUV (Deep Ultraviolet) systems, and have long-term aspirations to enter the EUV space, although this remains a significant challenge. SiCarrier has emerged as a notable domestic contender with ambitious plans. The company reportedly has developed lithography machines capable of processing 300mm wafers for 28nm and older process nodes using DUV technology. Furthermore, SiCarrier has announced a bold roadmap to launch an upgraded version of its lithography equipment by 2026-2027.
SMEE (Shanghai Micro Electronics Equipment Group) is historically China’s leading lithography equipment maker, known to produce machines capable of 28nm technology (SSA800), and is working on more advanced systems. While AMEC is not directly involved in lithography equipment manufacturing, its CEO has expressed the belief that 5nm process nodes might be achievable without EUV, potentially through multipatterning techniques combined with its etching and deposition tools. However, this remains a highly complex and unproven path for volume manufacturing at such advanced nodes. The development of EUV lithography in China faces immense challenges, including the need for high-power EUV light sources, precision optics, high-quality mirrors, and advanced resists, though Chinese entities have filed lots of patents in these areas in the last 2-3 years.
Future Outlook
The Chinese semiconductor equipment industry, spearheaded by companies like AMEC, Naura, ACM Research, Piotech, and the rapidly emerging SiCarrier, is undergoing a period of dynamic growth and ambitious technological advancement. These manufacturers have made significant strides in developing a wide array of critical tools, including etching systems, thin-film deposition (PVD, CVD, ALD) equipment, cleaning solutions, and are venturing into more complex areas like metrology, advanced packaging, and lithography. Their product roadmaps are characterized by aggressive R&D investment, a push towards supporting more advanced process nodes (with some targeting 5-7nm capabilities), and a strong focus on increasing domestic self-sufficiency to reduce reliance on international suppliers. This drive is fueled by both national strategic priorities and the growing demand from China’s expanding semiconductor manufacturing base.
Despite these advancements, Chinese equipment manufacturers still face considerable challenges in matching the breadth, depth, and cutting-edge performance of established global leaders such as ASML, Applied Materials, Lam Research, Tokyo Electron, and KLA. The global leaders benefit from decades of R&D, extensive intellectual property portfolios, deeply entrenched customer relationships, and complex global supply chains that are difficult to replicate quickly. Furthermore, geopolitical factors and export controls continue to pose hurdles for Chinese firms in accessing certain critical technologies and components.
Looking ahead, the future outlook for these Chinese semiconductor equipment manufacturers is one of continued rapid development and increasing competition. The substantial investments being made in R&D and manufacturing capacity are expected to yield further technological breakthroughs and enhance their ability to serve the demands of both domestic and, increasingly, international markets. Key trends to watch include the progress in indigenous lithography, the development of equipment for next-generation transistor architectures (like GAAFETs), and the expansion into advanced packaging technologies. While achieving parity with global leaders across the entire spectrum of semiconductor equipment will be a long-term endeavor, the progress made by these Chinese companies signifies a significant shift in the global semiconductor equipment landscape, promising a more diversified and competitive market in the years to come. Their success will be crucial not only for China’s semiconductor ambitions but also for the overall resilience and evolution of the global semiconductor supply chain.
