Silicon Wafers

Multiple Silicon WafersPCA 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.
