Procedure for fabricating semiconductors
Simplified illustration of the process of fabrication of a CMOS inverter on p-type substrate in semiconductor microfabrication. Each etch step is detailed in the following image. Note: Gate, source and drain contacts are not normally in the same plane in real devices, and the diagram is not to scale.
Wafer fabrication is a procedure composed of many repeated sequential processes to produce complete electrical or photonic circuits on semiconductor wafers in semiconductor device fabrication process. Examples include production of radio frequency (RF) amplifiers, LEDs, optical computer components, and microprocessors for computers. Wafer fabrication is used to build components with the necessary electrical structures.
The main process begins with electrical engineers designing the circuit and defining its functions, and specifying the signals, inputs/outputs a...
