Wafers are formed of highly pure (99.9999999% purity) nearly defect-free single crystal material. One process for forming crystalline wafers is known as Czochralski growth invented by the Polish chemist Jan Czochralski.
In electronics, a wafer (also called a slice or substrate) is a thin slice of semiconductor material, such as a silicon crystal, used in the fabrication of integrated circuits and other microdevices. The wafer serves as the substrate for microelectronic devices built in and over the wafer and undergoes many microfabrication process steps such as doping or ion implantation, etching, deposition of various materials, and photolithographic patterning.
