Product Description:

1. Structure of Monocrystalline Silicon Solar Wafer 125*125mm Description

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.
