Profile: Siltronic Corp. specializes in offering silicon wafers. Our products include polished wafers, epitaxial wafers and annealed wafers. We offer various types of polished silicon wafer with diameters from 125 to 300 mm. Standard polished wafers are manufactured with standard CZ crystal technology. Depending on the customer's needs, different kind of dopants are added like boron, phosphorus, red phosphorus, arsenic & antimony. Neutrondoped crystals, using radiation, are produced for special applications. The floatzone (FZ) method of silicon crystal production provides an ingot with considerable advantages. Due to the absence of oxygen in the molten silicon during the FZ process, there are no effects of thermal donors or oxygen precipitates. This produces a silicon wafer that has extremely stable resisitivity.
