Wafer (electronics) - Wikipedia

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 fabriion of integrated circuits and, in photovoltaics, to manufacture solar cells. The wafer serves as the substrate for microelectronic devices built in and upon the wafer

Cost Per Wafer - smithsonianchips.si.edu

Cost per wafer first enjoyed widespread use several years following the introduction of cost-of-ownership modeling by SEMAT-ECH, the consortium of semiconductor man-ufacturers in the U.S. Cost per wafer is often used to compare the cost-of-ownership per-formance of competing pieces of equipment. It is also used by semiconductor manufactur-

Silicon Carbide - an overview | ScienceDirect Topics

Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800 °C. In air, SiC forms a protective silicon oxide coating at 1200 °C and is able to use up to 1600 °C.

Silicon Carbide - an overview | ScienceDirect Topics

Silicon carbide is the hardest of the conventional abrasives but has lower impact resistance than aluminium oxide and shows a higher wear rate when used for grinding steels. Silicon carbide wears more rapidly when used to grind metals that have an affinity for carbon such as iron and nickel. It is therefore used primarily for non-ferrous materials.
