12″ Silicon Wafers
300mm wafers were introduced to the industry in 1995. Over the last several years, there has been a tremendous increase in 300mm (12″) wafer usage. Nearly all of the major chip manufacturers have already, or have plans to build 300mm fabrications and nearly all equipment manufacturers have designed their new equipment with 12″ wafers in mind. All 300mm wafers are double-side polished and have a notch identical to the notch found on 200mm wafers. There are many different grades of 300mm wafers, and we are a silicon wafer supplier that accommodates a very wide variety of customers.
If your project’s requirements are outside the specifications listed below, please contact SVM to speak with a member of our team and we will gladly check our multi-million dollar inventory for wafers that will fit your project’s requirements. If we do not have anything available we will custom manufacture wafers to meet your exact requirements. For these orders, it may require a minimum order quantity greater than our standard of 25 wafers (1 factory sealed cassette).
