Electrostatic discharge protection apparatus for semiconductor integrated circuit, has electrostatic discharge protection circuit connected in between doping zone and ground potential connection

摘要

An electrostatic discharge (ESD) protection apparatus has an ESD protection circuit (ESDSS) connected in between a doping zone formed as a substrate (S) and a ground potential connection (VSS) connected to the doping zone. The ESD protection circuit is designed so that the doping zone is at a minimum of potentials present at the supply voltage potential connections (VDD,VDDP) and at the ground potential connection.
