Silicon Wafer Manufacturing – How does it made ?
A wafer 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. Finally the individual microcircuits are separated (dicing) and packaged.
Silicon is a gray , brittle, tetravalent, nonmetallic element occurring abundantly in nature. The symbol for Silicon is Si it’s atomic number is 14 and it’s atomic mass is 28.086. Relative to how many impurities or dopants (Boron, Phosphorus, Arsenic, Antimony, etc.) are placed into it’s crystal structure.
