PSE Capsule

Supports treatment equipment of the next generation of single-wafer process.


The capsule uses a PSE membrane that has been received favorably. It is small in size and delivers a high flow rate and high precision.

The flow rate equivalent to that of conventional single (1-stage) products of other companies is realized with a half (1/2 stage) product.
The proprietary inner dense layer of the PSE membrane ensures reliable retention of fine particles.

Main applications

  • Filtration of purified water used by single-wafer wet cleaning equipment
  • Filtration of chemicals used by single-wafer wet cleaning equipment
  • Final rinsing water for developers
