The upgrading and iteration of semiconductor equipment heavily rely on technological breakthroughs in precision components. As the cornerstone of semiconductor equipment, these components underpin the development of the equipment industry.
Precision components also represent a challenging and highly technical segment in semiconductor equipment manufacturing. Under the high technological barriers, they have become one of the "chokepoint" segments in the semiconductor industry.
From a supply chain perspective, components directly impact the delivery of semiconductor equipment.
From a production value standpoint, the annual output value of semiconductor components reaches tens of billions of US dollars, driving exponential growth in the industrial scale of downstream segments and demonstrating strong industrial radiation capacity and influence.
In terms of capital expenditure, there is a continued increase in capital spending on domestic semiconductor equipment and components.
SEMI's "300mm Fab Outlook Report to 2027" points out that due to the recovery of the memory market and robust demand for high-performance computing and automotive applications, global spending on 300mm front-end fab equipment is projected to exceed 100 billion US dollars for the first time in 2025 and reach a historic high of 137 billion US dollars by 2027.
Equipment capital expenditure serves as a leading indicator for the expansion of wafer manufacturing capacity. Supported by high capital expenditure, wafer capacity is expected to maintain a rapid growth trend, and the demand for precision components supporting semiconductor equipment is likely to benefit from the recovery in equipment spending.
Overview of the Semiconductor Equipment Components Industry
Semiconductor components refer to those parts that meet the requirements of semiconductor equipment and technology in terms of materials, structure, precision, reliability, and stability.
Semiconductor equipment components have high parameter standards and complex manufacturing processes, covering multiple specialized fields and characterized by precision craftsmanship and small batch sizes.
The industry typically categorizes semiconductor equipment components based on their structural composition or functional roles.
According to the internal processes within the cavity of integrated circuit equipment, they can be divided into five major categories: power and radio frequency control, gas delivery, vacuum control, temperature control, and conveyance systems.
Classified by primary materials and functional uses, they can be categorized into twelve groups: silicon/silicon carbide parts, quartz parts, ceramic parts, metal parts, graphite parts, plastic parts, vacuum parts, sealing parts, filtration components, motion components, electronic control components, and other parts.
Based on service objects, they can be divided into two categories: precision machined parts and general purchased parts.
y type, they can be classified into six groups: mechanical, electrical, electromechanical, gas/liquid/vacuum systems, instrumentation, and optical categories.
Among these, mechanical components account for approximately 20%-40% of semiconductor equipment components; electrical components account for approximately 10%-20% and, as core components controlling the manufacturing process, pose significant challenges for technological breakthroughs.

Competitive Landscape of Semiconductor Equipment Precision Components
There is a wide variety of semiconductor precision components, and the overall market is relatively fragmented.
From a competitive landscape perspective, the global semiconductor equipment market is dominated by international manufacturers, with corresponding semiconductor equipment precision component manufacturers primarily based in the United States, Japan, and Taiwan region of China.
Due to the stringent precision and quality requirements for semiconductor components, only a handful of suppliers worldwide can provide products for any single semiconductor component. This results in a situation where, despite the overall industry concentration of semiconductor components being around 50%, the concentration within specific product categories often exceeds 80%-90%, indicating a pronounced monopoly effect.
Among the top ten leading suppliers of global semiconductor components, notable companies include ZEISS (optical lenses), MKS Instruments (MFC, RF power supplies, vacuum products), Edwards (vacuum pumps), Advanced Energy (RF power supplies), Horiba (MFC), VAT (vacuum valves), Ichor (modular gas delivery systems and other components), UltraClean Technology (sealing systems), ASML (optical components), and EBARA (dry pumps).
Most Chinese mainland manufacturers focus on individual production processes or specific component products, with relatively high localization rates for mechanical components and gas/liquid/vacuum system components.
According to VLSI Research data, over the past decade, the market share of the top ten global key subsystem suppliers has consistently remained at approximately 50%.
