Currently, five major companies including GlobalWafers control more than 80% of the global 300-mm silicon wafer manufacturing market and about 90% of silicon wafers are produced in east Asia.
Wafer size – largest wafer diameter that a facility is capable of processing. (Semiconductor wafers are circular.) Process technology node – size of the smallest features that the facility is capable of etching onto the wafers. Production capacity – a manufacturing facility's nameplate capacity. Generally max wafers produced per month.
Siltronic AG sells silicon wafers with diameters from 200 mm to 300 mm (8 to 12 inches) with many different features such as: Crystal growth according to Czochralski method or Float Zone method; Polished, epitaxial, as cut, lapped, etched surface; Silicon wafers are offered with boron, phosphorus, antimony and arsenic doping.
Wafers grown using materials other than silicon will have different thicknesses than a silicon wafer of the same diameter. Wafer thickness is determined by the mechanical strength of the material used; the wafer must be thick enough to support its own weight without cracking during handling. The tabulated thicknesses relate to when that process ...
