Semiconductor Equipment Industry Chain

Components & Subsystems（核心零部件与子系统（上游））Sector — Components account for 60–80% of tool cost. Vacuum, RF, optics and precision parts carry high technical barriers and are the deep water of equipment localization.

• Vacuum, Gas & Fluid Systems（真空与气液系统）Sector — Creates the vacuum environment and delivers gases and chemicals with precision — the foundational subsystems of etch and deposition tools.

  • Vacuum Pumps（真空泵）Component — Dry and turbomolecular pumps maintain chamber vacuum; frequently replaced, with a sizable aftermarket.🔒4

  • Mass Flow Controllers（气体流量控制器（MFC））Component — Meters process gases with 0.1%-level precision, directly determining film uniformity and etch accuracy.🔒3

  • Vacuum Valves & Fittings（真空阀门与管件）Component — High-purity vacuum valves and fittings; Switzerland's VAT dominates the gate-valve market.🔒2

  • Ultra-High-Purity Delivery Systems（高纯工艺介质系统）Component — Ultra-high-purity gas and chemical delivery systems and modules for both fab facilities and tools.🔒2

  • Vacuum Gauges & Sensors（真空计与传感仪表）Component — In-situ pressure and residual-gas instrumentation — the eyes of process stability.🔒2

  • Temperature Control Systems（温控与流体控制）Component — Chillers hold chamber and chuck temperatures precisely — one of the faster-localizing niches.🔒3

  • Lithography Light Sources（光刻光源）Component — Excimer lasers for DUV and EUV sources; ASML's acquisition of Cymer vertically integrated the field.🔒3

  • Precision Optics（精密光学部件）Component — Projection lenses and metrology optics; Zeiss SMT is ASML's sole lens supplier.🔒3

  • Wafer Stages & Motion Platforms（双工件台与运动平台）Component — Nanometer-precision motion systems — a key determinant of scanner throughput and overlay accuracy.🔒2

• Precision Parts（精密零部件）Sector — Chambers, ceramics, quartz and electrostatic chucks — consumable and structural parts with recurring replacement demand as installed base grows.

  • Chambers & Metal Parts（腔体与金属结构件）Component — Process chambers, liners and showerheads — precision metalwork with demanding surface-treatment and cleanliness specs.🔒2

  • Ceramics & Quartz Parts（陶瓷与石英件）Material — Plasma-resistant advanced ceramics and high-purity quartz chamber parts — classic high-turnover consumables.🔒3

  • Electrostatic Chucks（静电卡盘）Component — Holds wafers electrostatically with precise temperature control; a core etch/deposition part dominated by Japanese makers.🔒3

• Wafer Handling & Automation（晶圆传输与自动化）Component — Vacuum robots and EFEM front-end modules move wafers between chambers contamination-free.🔒3

Process Equipment（设备整机（中游））Sector — Process tools by manufacturing step — lithography, etch, deposition, cleaning, metrology, test and packaging — a market highly concentrated among US, Japanese and Dutch leaders.

• Lithography Systems（光刻设备）Equipment — Transfers circuit patterns onto wafers; an EUV scanner exceeds €150M and ASML monopolizes the EUV segment.🔒4

• Etch Systems（刻蚀设备）Equipment — Removes material with plasma to sculpt 3D structures — the main process step with the highest Chinese localization rate.🔒5

• Deposition Systems（薄膜沉积设备）Equipment — CVD, PVD and ALD grow films on wafers — among the largest and most diverse equipment categories.🔒5

• Coater & Developer（涂胶显影设备）Equipment — Coats and develops photoresist inline with scanners; Tokyo Electron holds roughly 90% global share.🔒3

• Cleaning Systems（清洗设备）Equipment — Advanced nodes require 200+ cleaning steps; single-wafer cleaning dominates and Chinese vendors are competitive.🔒4

• Ion Implantation（离子注入设备）Equipment — Implants dopant ions to tune electrical properties — high barriers, few players.🔒3

• CMP Systems（CMP抛光设备）Equipment — Chemical-mechanical planarization flattens wafers at nanometer scale — essential for advanced nodes and packaging.🔒3

• Thermal Processing（热处理设备）Equipment — Oxidation, diffusion and anneal furnaces; Beijing E-Town's Mattson is strong in rapid thermal processing.🔒4

• Photoresist Strip（去胶设备）Equipment — Dry-strip tools that remove photoresist after patterning; a concentrated market.🔒2

• Metrology & Inspection（量检测设备）Equipment — In-line measurement and defect inspection; KLA dominates, leaving one of the largest localization gaps.🔒4

• Test Equipment（测试设备）Equipment — ATE systems for wafer sort and final test; SoC and memory testers are the growth segments.🔒4

• Probers & Sorters（探针台与分选机）Equipment — Wafer probers and IC handlers that pair with testers; mechanically demanding.🔒3

• Packaging Equipment（封装设备）Equipment — Die attach, bonding and molding tools; advanced packaging (CoWoS, HBM) is driving demand for hybrid bonding.🔒4

Fabs & Applications（下游应用（下游））Sector — The buyers of equipment: foundries, memory makers, IDMs and OSATs. Their capex cycles drive the entire equipment industry.

• Foundries（晶圆代工）Manufacturing — The largest equipment buyers; TSMC alone spends over $30B in annual capex.🔒4

• Memory Manufacturing（存储芯片制造）Manufacturing — DRAM and NAND makers with pronounced capex cycles; the HBM boom is driving a fresh equipment upcycle.🔒5

• IDMs（IDM厂商）Manufacturing — Integrated device makers; power and analog expansions drive demand for specialty-process tools.🔒4

• OSATs（封装测试厂）Service — Outsourced assembly & test houses — the main buyers of packaging and test equipment, now racing to add advanced-packaging capacity.🔒5
