Semiconductor manufacturing process or semiconductor fabrication process refers to the series of steps used to create integrated circuits. The fabrication process comprises a series of chemical- and lithography-related steps whereby the electronic devices and circuits are built layer-by-layer on a piece of bulk substrate.

Overview

The series of steps required to create (or fabricate) a semiconductor device is called the semiconductor fabrication process. The fabrication process takes place in an ultra-clean factory called a foundry or a fab. A specific semiconductor fabrication process along with all its design rules is reffered to as a technology node. Although historically, the nomenclature of technolgoy nodes was to name them after the minimum feature size of the process, recent nodes have derailed into nothing more than a marketing named. Currently, leading-leading fabrication processes are called 14 nm, 10 nm, and 7 nm.
