Patent ID: 8728920

Claim:
A method of forming a Schottky diode in a semiconductor structure that includes an n-type region, the n-type region having a dopant concentration, the method comprising: implanting the semiconductor structure to form a first n-type strip and a second n-type strip in the semiconductor structure, the first n-type strip and the second n-type strip each having a dopant concentration that is greater than the dopant concentration of the n-type region, the second n-type strip being spaced apart from the first n-type strip, no doped region with an n-type and a dopant concentration greater than the dopant concentration of the n-type region touching both the first n-type strip and the second n-type strip; depositing a layer of metal; and reacting the layer of metal to form a first metal strip that touches a top surface of the first n-type strip, a second metal strip that touches a top surface of the second n-type strip, and a metal region that touches the semiconductor structure, lies laterally between the first metal strip and the second metal strip, and spaced apart from the first metal strip and the second metal strip.
