Understanding Silicon Wafers

A silicon wafer is a thin slice of semiconductor material, primarily silicon, used in the fabrication of integrated circuits and other microdevices. The wafer serves as the substrate for microelectronic devices built in and upon the wafer. The manufacturing process involves several steps, including doping, ion implantation, etching, thin-film deposition, and photolithographic patterning. The final product is a polished wafer ready for device fabrication .Wikipedia+1Wikipedia+1
