ABSTRACT:
A thyristor and a method for manufacturing the thyristor that includes a gate region extending from the first major surface into a semiconductor substrate and an anode region extending from the second major surface into the semiconductor substrate. A cathode region extends into a portion of the gate region. Optionally, enhanced doped regions extend into the gate and anode regions. A mesa structure having a height HGis formed from the first major surface and a mesa structure having a height HAis formed from the second major surface. The gate region extends under the first major surface of the semiconductor substrate and it extends vertically into the semiconductor substrate a distance that is greater than height HG. The anode region extends under the second major surface of the semiconductor substrate and it extends vertically into the semiconductor substrate a distance that is greater than height HA.
