TechZoom semiconductor company's basic manufacturing process involves building circuitry on a single silicon wafer one layer at a time.

TechZoom semiconductor company's basic manufacturing process involves building circuitry on a single silicon wafer one layer at a time. The same basic 5 steps (with variations dictated by the circuit design) are repeated for as many layers as needed, in this case 12 layers. Please see the process map below.

Steps involved in building one layer of circuit. Total of 12 layers for the wafer to complete processing.
