WebJan 12, 2024 · GlobalWafers specializes in 3” to 12” silicon wafer manufacturing, possessing a complete production line from ingot growth, slicing, etching, diffusion, polishing and epitaxy. Its high value products include Epi wafers, polished wafers, diffusion wafers, annealed wafers, SOI wafers, FZ wafers and compound wafers Siltronic AG 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 upon the … 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 Standard wafer sizes Silicon Silicon wafers are available in a variety of diameters from 25.4 … 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 Formation Wafers are formed of highly pure, nearly defect-free single crystalline material, with a purity of 99.9999999% (9N) or higher. One process for forming crystalline wafers is known as the Czochralski method, invented by Polish … See more Challenges There is considerable resistance to the 450 mm transition despite the possible productivity improvement, because of concern about … 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.
