Silicon on Insulator (SOI) is a new type of starting material for the chipmaking process. SOI wafers have three layers; a thin surface layer of silicon (from a few hundred Angstrom to several microns thick) where the transistors are formed, an underlying layer of insulating material on a support or “handle” bulk silicon wafer. The […]
