What Does Wafer Mean?
A wafer is a piece of silicon (one of the most abundant semiconductors available worldwide) or other semiconductor material, designed in the form of a very thin disc. Wafers are used to create electronic integrated circuits (ICs) and silicon-based photovoltaic cells. In these designs, the wafer serves as the substrate. Engineers use processes such as doping, implantation and etching to complete the build of the integrated circuit.
Techopedia Explains Wafer
The doping of silicon wafers and other innovations in building microprocessors is a continuation of technology following Moore’s Law, which, in 1965, stated that the density of transistors able to be produced on a given surface area doubles every two years. This law has been vindicated by the rapid innovation of microprocessors. First, there was small-scale circuit integration, then medium-scale circuit integration, then large-scale circuit integration, and then finally very large-scale and ultra-large-scale integration.
