what is a Wafer

Wafer Semiconductor manufacturing begins with a thin disk of semiconductor material, called a “wafer.” A series of processes defines transistors and other structures, interconnected by conductors to build the desired circuit.
The wafer is then sliced into “dice” which are mounted in packages, creating the IC.
Wafer Fab Semiconductor processing facility which turns wafers into integrated circuits. A typical wafer fab employs a series of complex steps to define conductors, transistors, resistors, and other electronic components on the the semiconductor wafer. Imaging steps define what areas will be affected by subsequent physical and chemical processes.
