A compound of arsenic and gallium elements, GaAs Wafer, is one of the products that constitute the raw materials of chips. Ga stands for gallium and As stands for arsenic in the word  GaAs . Gallium in a  GaAs  Wafer is in general used in the production of semiconductors, barometers, light emitting diodes, thermometers and electronic circuits. It is a silvery metal and quite soft which makes it easy to be used in chips as well. Gallium element, which is a kind of post transitional metal, has the ability to bond easily with most of the metals on earth. It is highly deployed in the production of low melting alloys. Gallium arsenide of a GaAs Wafer has the attribute of generating laser light from electricity in a direct manner. There are two types of GaAs Wafer; polycrystalline and single crystal. These wafers are utilized in micro electronics and opto electronics production in order to make LED, microwave circuits and LD. It is deployed in solar panels also. http...

* A wafer, also called a slice or substrate , is a thin slice of semiconductor material , such as a crystalline silicon , used in electronics for the fabrication of integrated circuits and in photovoltaics for conventional, wafer-based solar cells . * 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 . * Finally the individual microcircuits are separated ( dicing ) and packaged . * One process for forming crystalline wafers is known as Czochralski growth invented by the Polish chemist Jan Czochralski . * In this process, a cylindrical ingot of high purity mono crystalline semiconductor, such as silicon or germanium , called a boule , is formed by pulling a seed crystal from a ' m...
