Ultrasil LLC

Ultrasil LLC is located in Hayward, California in the heart of Silicon Valley. The company opened in 1997, producing standard silicon wafers SSP ( single side polished ) test silicon wafers and prime silicon wafers. In 1999, Ultrasil started production of DSP (double side polished) Silicon Wafers. We shipped our first SOI (Silicon on Insulator) wafer in 2001. Since then we have expanded our product line to include double bonded SOI Wafer, Wafer-to-wafer bonding,  and SOI Wafers with Ion implants and coatings.
