Global Functional Water Generation and Supply Systems for Semiconductor Market Strategic Research Report

Scope of the Report

The global Functional Water Generation and Supply Systems for Semiconductor market size is predicted to grow from US$ 164 million in 2025 to US$ 344 million in 2032; it is expected to grow at a CAGR of 10.2% from 2026 to 2032.

Functional Water Generation and Supply Systems for Semiconductor Wet Processes refer to point-of-use or near-point-of-use systems that convert ultrapure water into process-specific functional water for semiconductor wet cleaning, stripping, post-CMP cleaning, reticle cleaning, and advanced packaging cleaning applications. These systems typically use gas dissolution, membrane contactors, ejector mixing, electrolysis, degassing, pH/ORP adjustment, online concentration monitoring, closed-loop control, and ozone off-gas or dissolved ozone decomposition technologies to generate ozonated UPW, hydrogenated UPW, carbonated water, ammonia water, nitrogen-dissolved water, degassed water, or other functional water streams. Key performance parameters include dissolved gas concentration, flow rate, concentration stability, metal ion control, particle cleanliness, response time, safety interlocks, compatibility with semiconductor wet tools, and integration with fab utility and process control systems.

The market for functional water generation and supply systems in semiconductor wet processes should be understood as a process-enabling auxiliary equipment market rather than a generic water treatment market. The core function is to convert ultrapure water into process-specific functional water such as ozonated UPW, hydrogenated UPW, carbonated water, ammonia water, degassed water, or other controlled water chemistries with defined pH, ORP, dissolved gas concentration, and contamination performance. The value proposition is shifting from chemical reduction and environmental compliance to defect control, material compatibility, and process window optimization for advanced semiconductor manufacturing.

From a supply-side perspective, the industry is structurally concentrated around Japanese and U.S. technology leaders, with meaningful regional participation from South Korea, Taiwan, and emerging Chinese domestic suppliers. MKS and EBARA remain highly relevant in semiconductor ozone and ozonated water systems. Kurita, Organo, and Nomura Micro Science leverage their ultrapure water engineering base to provide functional water systems. HJS ENG and Trusval represent important regional players in Korea and Taiwan, while Qingdao Guolin Semiconductor and Suzhou Jingtuo Semiconductor are among the more visible Chinese domestic suppliers. The broader longlist is much larger, but many companies are either generic ozone equipment vendors, wet cleaning tool OEMs, or service providers rather than dedicated semiconductor-grade functional water system manufacturers.

On the demand side, ozonated water is the most mature and commercially significant category, mainly used for organic removal, photoresist residue removal, metal contamination control, surface oxidation, and chemical reduction in wet cleaning. Hydrogen water, CO₂ water, ammonia water, and degassed water are more closely linked to particle control, anti-static performance, post-CMP cleaning, and corrosion/material compatibility. Growth is expected to be supported by new 300mm fabs, advanced logic and memory capacity additions, advanced packaging process expansion, green fab initiatives, and localization in China.

From a technology roadmap perspective, competition is moving from basic functional water generation toward high-concentration, high-stability, low-metal, low-particle, fast-response, closed-loop, and safety-compliant systems. The market is unlikely to replace conventional wet chemicals entirely, but it should continue to gain share in low-chemical cleaning, advanced node defect reduction, and environmentally driven process optimization.
