4″ Silicon Wafers

Silicon Valley Microelectronics carries a full line of 100mm silicon wafers. Please see below a range of our SEMI standard specifications for test grade wafers. Every customer’s specification is unique and SVM can supply wafers that meet your exact specifications.

If your requirement does not fall under the given specifications, please contact us so we can find a substrate that best fits your needs. We would be happy to custom manufacture wafers to fit your project’s exact requirements. This will often require a minimum order quantity larger than our standard 25 wafers (1 cassette).
