200 mm (8″) wafers were introduced in 1985 and are still considered the industry standard today.There are more 200 mm 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 200 mm wafers in our multi-million dollar inventory. Here are examples of some of the specifications available.
