Particle getter®

Suggestions for reducing particles

In film formation by vapor deposition and sputtering, particles adhere not only to the target but also to the mask and shield inside the device.

As the deposited film thickness increases, the risk of film peeling increases, and the peeled pieces become particles.

The PG (Particle Getter) sheet is a copper plate that has been specially processed to suppress the peeling of the film that has adhered to the inside of the equipment. Particle getter ® has a unique surface condition and excellent stress relaxation of the adhered film to suppress peeling and reduce particles.
