In photolithography, ultraviolet light is shined onto a photosensitive film on a piece of silicon to create a pattern of conducting and isolating layers as it breaks apart. The circuit is built up with many of these silicon layers and covered in metal. Finally, another photosensitive film is used to form a pattern for the wires.

Stepping is an efficient method for producing computer chips. It quickly creates chips one after another by exposing a large silicon wafer to ultraviolet light in sections.

The silicon used in computer circuits is pure silicon crystal to ensure perfection. Silicon is used because it is a cheap and abundant semiconductor.
