PCA has been creating silicon wafers for about half a century
Polishing Corporation of America has been creating the future from the very beginnings of the semiconductor industry.
We created the first wax-free method of polishing to obtain ultra-flatness at very low cost of manufacture.
We manufacture wafers of any diameter and now ultra-flat 400mm diameter wafers in our modern facility located in the heart of Silicon Valley. We produce to SEMI Standards or unique specifications.
