Diameter 2'' to 8'' Polished Silicon Wafer in Prime, Test, Monitor, SEMI Standard
Silicon wafers are used as a substrate material in a wide range of applications. They are the building block of modern electronics. BonTek offers Prime, Test, Monitor, SEMI standard, and customized silicon wafers in all diameters from 2″ to 300mm. Our silicon wafers are made from ingot using the most commonly known crystal growing process called the Czochralski (CZ) process.
We carry a wide selection of Prime Semi Standard CZ wafers in stock at all times. Any wafer we have in stock can be ready to ship within a day. In some cases, the same day as the order is placed.
