Floating zone wafer
WebA float zone wafer is a wafer that's made of pure silicon using the floating zone method. Wafers like this come with low concentrations of carbon and oxygen impurities that make them ideal for various applications. If you need more information about this wafer and method, here are some advantages of using the float zone method. WebSiltronic’s product portfolio is extensive and ranges from non-polished wafers to epitaxial wafers with diameters up to 300mm. The wafers are manufactured from monocrystalline silicon ingots that have been made …
