Junction barrier Schottky diode
Abstract:
A junction barrier Schottky diode has N-type well having a surface and first peak impurity concentration; P-type anode region in surface of the well having second peak impurity concentration; N-type cathode contact region in surface of the well and laterally spaced from a first wall of the anode region having third peak impurity concentration; and first N-type region in surface of the well and laterally spaced from second wall of the anode region having fourth impurity concentration. Center of the spaced region between the first N-type region and the second wall of the anode region has fifth peak impurity concentration. Ohmic contact is made to the anode region and cathode contact region. Schottky contact is made to the first N-type region. First and fifth peak impurity concentrations are less than the fourth peak impurity concentration. The fourth peak impurity concentration is less than the second and third peak impurity concentrations.
