Webmodel of a 6" diameter Si wafer with a 5.4" diameter Al film on it. The hatched portion represents the Al film. The wafer is perfectly circular except for a flat of 2.6" at the top. The initial thickness of the wafer is 25 mils where as the Al film layer is only 5 um thick. The wafer is finally back-ground to a thickness of 6 mils. In electronics, a wafer (also called a slice or substrate) is a thin slice of semiconductor, such as a crystalline silicon (c-Si), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells. The wafer serves as the substrate for microelectronic devices built in and … See more In the semiconductor or silicon wafer industry, the term wafer appeared in the 1950s to describe a thin round slice of semiconductor material, typically germanium or silicon. Round shape comes from See more Challenges There is considerable resistance to the 450 mm transition despite the possible productivity improvement, because of concern about insufficient return on investment. There are also issues related to increased inter … See more While silicon is the prevalent material for wafers used in the electronics industry, other compound III-V or II-VI materials have also been employed. Gallium arsenide (GaAs), a III-V semiconductor produced via the Czochralski method, gallium nitride (GaN) and See more Formation Wafers are formed of highly pure, nearly defect-free single crystalline material, with a purity of … See more Standard wafer sizes Silicon Silicon wafers are available in a variety of diameters from 25.4 mm (1 inch) to 300 mm (11.8 inches). See more In order to minimize the cost per die, manufacturers wish to maximize the number of dies that can be made from a single wafer; dies always have a square or rectangular shape due to the constraint of wafer dicing. In general, this is a computationally complex See more • Die preparation • Epitaxial wafer • Epitaxy • Klaiber's law See more
