450mm silicon wafer

18 inch silicon wafer

The main content of this section are: the sand into the preparation of semiconductor grade silicon, then transform it into crystals and wafer, and the process steps required by the production of polished wafers. Including the operation used in the manufacture of different types of description of the wafer. 450 mm diameter growth of crystal and 450 mm wafer preparation is challenging.
