Ultrapure Water for Semiconductor Manufacturing
Advanced semiconductor manufacturing relies on ultrapure water (UPW) with impurity levels measured in parts per trillion (ppt). Even trace contaminants can impact device yield, reliability, and process consistency. SnowPure supplies high-technology water purification components that enable OEMs and system integrators to design and deliver reliable UPW systems for semiconductor fabrication facilities.
Proven EDI and UV Technologies for Electronics and Semiconductor Applications
SnowPure has supplied electrodeionization (EDI) technology to the electronics and semiconductor markets since before 1997. Our OEM partners support installations in more than 90 countries, including the United States, Europe, Japan, and China.
SnowPure components are used in ultrapure water systems serving:
- Semiconductor fabrication
- Electronics manufacturing
- Solar panel production
- Hard disk drive and memory manufacturing
- Optical glass and precision lens fabrication
- Flat panel display manufacturing
EDI and UV-TOC in Modern UPW System Design
EDI, GTM, and UV-TOC reduction are key technologies in modern semiconductor water purification systems. SnowPure technologies can be used to replace or complement traditional mixed-bed resin deionization, reducing chemical handling while improving consistency and operating cost.
A common system architecture includes:
- Centralized RO–EDI–UV treatment to achieve very low ionic and organic contamination
- Local polishing at individual tools to achieve resistivities up to 18.18 MΩ·cm at the point of use
This approach supports stable water quality while simplifying regeneration logistics and minimizing chemical usage.
Chemical-Free Ultrapure Water Components
SnowPure products used in semiconductor UPW applications are chemical-free and designed for high reliability and long service life in continuous operation environments.
Key products include:
- Electropure™ XL-R EDI modules
- Electropure™ EXL EDI modules
- Liqui-Cel membrane gas removal
- SPUV™ ultraviolet systems — compact, energy-efficient designs for TOC reduction and microbial control
Designed for OEMs and System Integrators
SnowPure supplies components only, not complete water systems. This non-competing model allows us to work closely with OEMs and integrators as a trusted technology partner in high-purity and ultrapure water system design.
