Virginia Semiconductor, Inc. (VSI) is a leading manufacturer of prime silicon substrates. Production quantities of 1-150mm diameter silicon, and small quantities of custom-silicon substrates are manufactured at VSI. SOI substrates are the fastest growing VSI product; VSI offers 100mm, 150mm, 25.4mm, 50.8mm, and 76.2mm diameter SOI manufactured by silicon wafer bonding. As always, VSI can actually make any silicon wafer to any specification and continues to supply small, complicated orders to valued customers. Many VSI customers require double-side-polished silicon wafers. Crystal growth, grinding, slicing, lapping, polishing, oxidation, and SOI are all in-house manufacturing activities being achieved at our Fredericksburg, Virginia facility.
