Classification: CPC H | IPC H

Claim 0:
1. A method of forming an integrated circuit, comprising:
forming a first terminal over a semiconductor substrate having a first conductivity type;
forming a second terminal between the first terminal and a surface of the semiconductor substrate, the first terminal being separated from the second terminal by a dielectric layer;
forming a first p-n junction between the semiconductor substrate and the second terminal, the first p-n junction having a first orientation with respect to the substrate surface;
forming a second p-n junction between the first p-n junction and the second terminal, the second p-n junction having a second opposite orientation with respect to the substrate surface; and
forming a third p-n junction between the second p-n junction and the second terminal, the third p-n junction have the first orientation.
