Patent ID: 7700449

Claim:
A method of forming an electrostatic discharging (ESD) device, the method comprising: providing a substrate; forming a first and a second semiconductor fin over the substrate and adjacent to each other, wherein each of the first and the second semiconductor fins comprises a first and a second end portions, and a middle portion between the first and the second end portions; epitaxially growing a semiconductor material on the first and the second semiconductor fins, wherein a first portion of the semiconductor material grown from the first semiconductor fin joins a second portion of the semiconductor material grown from the second semiconductor fin, and wherein the semiconductor material extends continuously from over the first end portion to second end portion of the first and the second semiconductor fins; implanting a first end of the semiconductor material and the first end portion of the first and the second semiconductor fins to form a first implant region; and implanting a second end of the semiconductor material and the second end portion of the first and the second semiconductor fins to form a second implant region, wherein a P-N junction is formed between the first end and the second end of the semiconductor material.
