The new facility, which became fully operational in late April 2008, provides in-house trace metals analysis and the capability to clean and fill containers in a tightly-controlled environment. The Sheboygan campus was selected as the site for the new cleanroom as it already provides large-scale manufacturing of products for the material science industry for SAFC, which supports the silicon semiconductor, compound semiconductor and performance materials markets.

The extension of the Sheboygan campus enables SAFC Hitech to produce, package and analyze its products in one location, completing the total supply chain, eliminating the need to use outside facilities and ensuring customers an uninterrupted supply of the highest quality materials required for advanced semiconductor manufacturing.
