Microfabrication

Microfabrication is making things which are very small. The earliest micromanufacturing was used to make the different parts of a computer circuit board.

Uses

Microfabrication is used a lot in electronics.

Microfabrication Media

• 

  Synthetic detail of a micromanufactured integrated circuit through four layers of planarized copper interconnect, down to the polysilicon (pink), wells (greyish) and substrate (green)

• 

  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. The diagrams are not to scale, as in real devices, the gate, source, and drain contacts are not normally located in the same plane.

• 

  Simplified illustration of dry etching using positive photoresist during a photolithography process in semiconductor microfabrication. Note: Not to scale.
