It is a semiconductor dust-free production workshop, because tiny particles can cause defects in electronic components and circuits, so it is very demanding
Wafer Fab refers to: the production technology of converting wafers into integrated circuits becomes a semiconductor processing process. Typical wafer processing processes define conductors, transistors, resistors and other electronic components on semiconductor wafers through a series of complex processes. The imaging process defines which areas are affected by subsequent physical and chemical processes.
Fabrication is an industrial word. Generally speaking, fabrication of a sheet metal is caused by hand or mold stamping to produce plastic deformation to form the desired shape and size, and then more complex parts can be formed by welding or a small amount of machining.
