Abstract
In a method for manufacturing an electrostatic discharge protection circuit, an electrostatic discharge device structure is formed during a front side processing of a semiconductor substrate in a first area. Contact pads are formed on the front side on the electrostatic discharge device structure and in a second area. During back side processing of the semiconductor substrate, a metal connection between the first electrostatic discharge device structure and the second area is formed.
