ABSTRACT:
An integrated circuit device comprising a diode and a method of making an integrated circuit device comprising a diode are provided. The diode can comprise an island of a first conductivity type, a first region of a second conductivity type formed in the island, and a cathode diffusion contact region doped to the second conductivity type disposed in the first region. The diode can also comprise a cathode contact electrically contacting the cathode diffusion contact region, an anode disposed in the island, an anode contact electrically contacting the anode, and a first extension region doped to the first conductivity type disposed at a surface junction between the first region and the island.
