Abstract
An ESD protection structure formed within a semiconductor substrate of an integrated circuit device. The ESD protection structure comprises a thyristor structure being formed from a first P-doped section forming an anode of the thyristor structure, a first N-doped section forming a collector node of the thyristor structure, a second P-doped section, and a second N-doped section forming a cathode of the thyristor structure. A low-resistance coupling is provided between an upper surface region of the collector node of the thyristor structure and the anode of the thyristor structure.
