Schottky diode and integrated circuit including the same

A schottky diode comprising:

• a conduction layer of an N-type;
• a well region of a P-type disposed in the conduction layer;
• a first junction region of the P-type having a ring shape in the conduction layer and surrounding the well region, wherein the ring shaped first junction region is spaced apart from the well region;
• an isolation region having a ring shape in the conduction layer and surrounding the ring-shaped first junction region, wherein the ring-shaped isolation region is adjacent the ring-shaped first junction region;
• a second junction region of the N-type having a ring shape in the conduction layer and surrounding the isolation region, wherein the ring-shaped second junction region is adjacent the ring-shaped isolation region;
• and
• a schottky electrode covering a schottky junction surface corresponding to an upper surface of the conduction layer between the first well region and the ring-shaped first junction region.
