Chips and Wafers

- Wafers
In electronics, a chip is an integrated circuit with millions of transistors, resistors, and capacitors, while a wafer is the base of any integrated circuit.
Wafers (also known as slices or substrates) are thin slices of semiconductors, such as crystalline silicon (c-Si), used to make integrated circuits and, in photovoltaics, to make solar cells.
Wafers serve as substrates for microelectronic devices built into and on the wafers. It undergoes many microfabrication processes such as doping, ion implantation, etching, thin film deposition of various materials, and photolithographic patterning.
Finally, individual microcircuits are separated and packaged into integrated circuits by wafer dicing.
