Wafer (electronics)
Videos
In electronics, a wafer is a thin slice of semiconductor, such as a crystalline silicon, used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells.

Photolithography is a process that involves using light to transfer a pattern onto a photoresist layer deposited on a sample, typically a silicon wafer. It is used in the manufacturing of integrated c

…upon the wafer. It undergoes many microfabrication processes, such as doping, ion implantation, etching, thin-film deposition of various materials, and photolithographic patterning. Finally, the individual microcircuits are separated by wafer dicing and packaged as an integrated circuit. In the semiconductor industry…
