YZ001 & YZ002 Uniform Particle Resin | European Semiconductor Ultra-Pure Water Project

2026-02-11

Project Background

A professional semiconductor wafer manufacturing facility in Germany requires ultra-high-purity process water for core chip etching and precision cleaning processes. The plant’s original standard mixed bed resins featured uneven particle sizes, which caused water flow channeling, unstable resistivity output and occasional TOC exceedance. These inconsistencies negatively impacted wafer yield rates and overall production stability.

On-Site Challenges

1. Uneven resin particle sizes resulted in irregular water distribution and low ion exchange efficiency.

2. Conventional resins contained excessive soluble leachables and failed to meet strict electronic-grade water purity specifications.

3. Limited anti-fouling resistance led to gradual performance decay during long-term continuous operation.

Customized Solution

We recommended electronic-grade YZ001 uniform particle cation resin and YZ002 uniform particle anion resin as the final-stage polishing mixed bed. With tightly controlled particle uniformity, the resins eliminate bed flow channeling, minimize soluble impurity release and deliver outstanding organic fouling resistance. We also optimized the system regeneration schedule to guarantee consistent high-purity water output over extended operation cycles.

Application Results

1. The ultrapure water system maintains a stable resistivity of 18.2 MΩ·cm with TOC levels consistently below 1ppb, fully meeting international semiconductor manufacturing purity standards.

2. Overall system stability is significantly enhanced, and continuous water production runtime is effectively prolonged.

3. Consistent ultra-high water purity has helped the facility improve wafer yield and reduce production defect rates.

Client Review

“These uniform particle resins deliver exceptionally stable ultrapure water performance, fully satisfying our rigorous requirements for high-precision semiconductor manufacturing.” —— Water System Engineer, German Semiconductor Factory
