Fabrication

The process of creating integrated circuits is called Fabrication. It is a sequence of chemical and photographic steps in which the circuits are constructed on a semiconductor material known as "wafer". The steps are described below:

Lithography

In this step, a layer of photo-resisting liquid is applied on the surface of semiconductor or wafer. It is then backed and hardened.

Etching

In etching process, unwanted material is removed from the wafer. Then the pattern of the photo-resist is transferred to the wafer.

Deposition

In this step, films of different materials are applied on the wafer. It is done by either "Physical Vapor Deposition" or "Chemical Vapor Deposition".

Oxidation

In the oxidation process, the silicon layers on the top are converted to silicon dioxide by oxygen or water molecules.

Diffusion

Diffusion is carried out to anneal the lattice defects.

>that sounds totally doable.
