STRUCTURE HAVING AN ELECTROSTATIC DISCHARGE CIRCUIT OF A SEMICONDUCTOR DEVICE AND A METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: An electrostatic discharge(EDS) circuit of a semiconductor device is provided to minimize damage to a junction diode connected to a pad. CONSTITUTION: An electrostatic discharge(EDS) circuit of a high voltage semiconductor device including a ground pad, a power pad, a plurality of electrical signal pads and an internal circuit comprises: at least one metal oxide semiconductor(MOS) transistor of which a source region and a drain region are connected to the electrical signal pad; and a Zener diode connected to the source region of the MOS transistor.
