Minimal Contamination in Plasma Process

Puruz 7529
Compound Description
Puruz 7529 is a compound specifically developed for plasma and gas deposition processes where seal reliability and very minimal contamination are essential. This material provides excellent chemical compatibility and is available in an infinite geometries and cross sections. It has been specifically formulated for minimal particle generation in oxygen and fluorine containing plasmas and is well-suited for both static and dynamic applications, i.e., slit valve door, gas feed-through, chamber lid, etc. It remains stable at service temperatures as high as 230°C. Class 100 post-cleaning and packaging is adapted for parts made from Puruz 7529.
