8″ Silicon Wafers

200mm silicon wafers were introduced in 1985 and are still considered the industry standard today. There are more 200mm (8″) wafers produced world wide than any other diameter. These wafers are used for a variety of applications that include testing and calibrating equipment to devices that might be used in your cellular phone or flat screen television. SVM carries a large variety of 200mm wafers in our multi-million dollar inventory. Below is an example of some of the 200mm specifications we typically carry.

If your project’s requirements are outside of the capabilities listed below, please contact SVM so we can check our multi-million dollar inventory. If we do not have your wafers available we can custom manufacture them to fit your exact specifications. Custom manufactured wafers may require a minimum order quantity greater than our standard minimum of 25 wafers (1 cassette).
