Abstract:
1. An integrated circuit including a junction barrier Schottky diode, the diode comprising: an N-type silicon well having surface; a P-type anode region in the surface of the well; a portion of the surface of the well horizontally abutting the anode region being an n-type Schottky region; a first silicide layer on the Schottky region and an adjoining portion of the anode region, the first silicide layer forming a Schottky barrier with the Schottky region; a second silicide layer of a different material than the first silicide layer on the anode region; and an ohmic contact to the second silicide layer on the anode region, and an ohmic contact to the well, wherein the first and second silicide layers are spaced from each other on the surface.
