Patent ID: 8368166

Claim:
A junction barrier Schottky diode, the diode comprising: an N-type well having a surface and a first peak impurity concentration along a vertical axis; a P-type anode region in the surface of the well, and having a second peak impurity concentration along a vertical axis; an N-type cathode contact region in the surface of the well and laterally spaced from a first wall of the anode region, and having a third peak impurity concentration along a vertical axis; a first N-type region in the surface of the well and laterally spaced from a second wall of the anode region, and having a fourth impurity concentration along a vertical axis; the center of the spaced region between the first N-type region and the second wall of the anode region having a fifth peak impurity concentration along a horizontal axis; an ohmic contact to the anode region and cathode contact region, and a Schottky contact to the first N-type region; and the first and fifth peak impurity concentrations being less than the fourth peak impurity concentration, and the fourth peak impurity concentration being less than the second and third peak impurity concentrations.
