The company continues to focus on penetrating mature chip manufacturing markets and building a robust customer base among leading foundry and semiconductor manufacturers, particularly in Asia, experiencing a majority of its sales in this region.

B. Products and Technology

Product Offerings

ACM Research specializes in a diverse portfolio of products geared towards front-end and back-end semiconductor manufacturing processes. Key product categories include:

1. Wafer Cleaning Equipment: Utilizing proprietary technologies such as Space Alternated Phase Shift (SAPS), Timely Energized Bubble Oscillation (TEBO), and Tahoe, the company’s single-wafer wet-cleaning tools effectively remove defects from wafer surfaces without inflicting damage, even at advanced process nodes of 22nm and below.
2. Advanced Packaging Equipment: The company offers a range of tools for back-end wafer assembly and packaging, including coaters, developers, etchers, and copper plating tools. These tools are custom-made, incorporating features requested by customers for enhanced productivity and efficiency.
3. Furnace Equipment: ACM Research’s furnace technology is designed for various deposition and thermal treatment applications, addressing the specific needs of semiconductor manufacturers.
4. Other Processing Tools: This category includes systems specifically designed for electrochemical plating (ECP), stress-free polishing, and various wafer processing applications.

Proprietary Technologies

ACM Research has developed several proprietary technologies that serve as the foundation for its equipment offerings:

• SAPS Technology: Allows for uniform delivery of megasonic energy across an entire wafer, resulting in enhanced defect removal efficiency, particularly at smaller defect sizes.
• TEBO Technology: Provides a controlled method for cleaning fragile patterned wafers, significantly reducing the risk of damage during the cleaning process.
• Tahoe Technology: Delivers high cleaning performance while minimizing the use of environmentally harmful chemicals, addressing both cost and regulatory challenges for manufacturers.

The company continuously invests in research and development, focusing on enhancing existing technologies and exploring new process capabilities that cater to emerging needs within the semiconductor manufacturing sector.

C. Market Opportunity

The global market for wafer fabrication equipment (WFE) is a critical segment for ACM Research. In 2023, the company estimated its addressable market to be approximately $16 billion. By product lines, significant market opportunities include:

• Wafer cleaning equipment: $5.2 billion
• Plasma-Enhanced Chemical Vapor Deposition (PECVD): $4.3 billion
• Furnace Equipment: $2.2 billion
• Track Equipment: $2.5 billion
• Electro-Chemical Plating (ECP): $800 million
• Stress-free polishing, advanced packaging, and other processing equipment: $900 million

The global semiconductor WFE market has experienced fluctuations, with an anticipated decline in total available global market segments from $21.2 billion in 2022 to an estimated $18.7 billion in 2023, indicating challenges but also opportunities for companies like ACM Research to capture market share through innovation.

D. Customer Base and Sales Strategy

To establish a solid foothold in the semiconductor industry, ACM Research has strategically aligned its sales and marketing efforts to build relationships with leading foundry, logic, and memory chip makers. The company's customer base encompasses significant companies in the semiconductor landscape, predominantly located in Asia.

The sales strategy employs a "demo-to-sales" approach, where evaluation or “first tools” are placed with select customers for testing and feedback. This has facilitated credibility and a referenceable base, influencing decisions among other manufacturers.

For instance, in 2023, a substantial share of revenue—45.5%—was derived from three key customers: SMIC, SiEn, and CXMT, highlighting the company’s reliance on a few dominant players while also illustrating the need for continued diversification in its customer base.

E. Manufacturing and R&D

ACM Research carries out most of its product development and manufacturing in mainland China, with additional operations in Korea. The manufacturing facility in Pudong, Shanghai, spans 236,000 square feet and focuses on producing tools built to order. The company is also expanding its production capacity with an ongoing multi-year construction project for a new facility in Lingang, Shanghai, aimed at accommodating advanced manufacturing systems and greater research and development capabilities.

In terms of research and development, the company recognizes its critical role in sustaining competitive advantage within the rapidly evolving semiconductor industry. ACM Research allocates substantial resources toward R&D, with 16.6% of its 2023 revenue devoted to this area. Innovations are aimed at enhancing existing products and developing new solutions to meet the ever-increasing technical requirements of customers.

F. Intellectual Property

Intellectual property (IP) protection is a key element of ACM Research's strategy, given its reliance on proprietary technologies for competitively positioning itself in the market. The company has been proactive in patent filings since its inception, resulting in a robust portfolio of over 498 patents across various jurisdictions, including the U.S., mainland China, Japan, and several others.

Protection of intellectual property is essential not only for safeguarding innovations but also for maintaining a competitive edge in a landscape characterized by active and often contentious IP litigations. This emphasis on IP protection establishes a foundation for potential future licensing opportunities while mitigating risks associated with infringement claims.

G. Competitive Landscape

The semiconductor equipment industry poses intense competition with numerous established players and emerging companies vying for market share. ACM Research faces competition from notable entities such as Lam Research Corporation, Applied Materials, and Tokyo Electron, among others. The competitive environment is influenced by factors such as product performance, innovation, market presence, and customer relationships.

To maintain competitiveness, ACM Research must consistently demonstrate innovation and reliability in its technology offerings while building strong relationships within its target markets, particularly in Asia, where the majority of its revenue is currently generated.
