2″ Silicon Wafers

Silicon Valley Microelectronics carries a full line of 50mm wafers. Please see below a SEMI standard specification for test grade wafers. Every customer’s specification is unique and SVM can supply wafers that meet your exact specifications. SVM’s 27 years of experience with wafers ensures customers have both short and long term supply of their specification.

SVM offers bare 50mm silicon wafers, as well as custom films and processing. Wafers in stock can usually ship with 1 business day, while custom orders have varying lead times depending on what films and processes the wafer needs.

If your desired specifications are outside of what is listed below, contact SVM to speak with a member of our team and we’d gladly custom manufacture wafers to fit your project’s requirements. Custom specifications may require a minimum order quantity greater than our typical order minimum of 25 wafers (1 cassette).
