Patent ID: 7259440

Claim:
A fast recovery diode, comprising: a first n-type layer having a first conductivity, the first n-type layer having an upper surface and a lower surface and a first edge and a second edge, the second edge provided on an opposing side of the first edge; a first p-type region provided proximate the upper surface of the first n-type layer and extending substantially the entire upper surface of the first n-type layer, the first p-type region having a first depth, the first p-type region including platinum; a first n-type region provided proximate the first edge of the first n-type layer and abutting an end of the first p-type region, the first n-type region extending from the upper surface of the first n-type layer to a second depth, the second depth being greater than the first depth to reduce leakage current; a first electrode provided proximate the upper surface of the first n-type layer; and a second electrode provided proximate the lower surface of the first n-type layer.
