High Purity Polysilicon

SRS supplies some of the highest purity polysilicon materials to its customers including a high purity 5mm-15mm product that is unmatched by any other OEM polysilicon supplier.  While consisting of industry leading bulk properties, SRS’ polysilicon materials also lead the market in surface purity with solar products typically <5 ppbw 17 metal and semi products typically <1 ppbw 17 metal on the surface.
