Claim:
1. A Schottky diode structure, comprising: a semiconductor substrate having an active region; a first well region having a first conductive type formed in the active region; a first doped region having the first conductive type formed on the first well region; first electrodes disposed on the active region, covering and contacting the first doped region; a second electrode centrally disposed on the active region, contacting to the first well region; gate structures disposed on opposing lateral sides of the second electrode, wherein the second electrode, which is an anode of the Schottky diode, is separated from the gate structures; and a second doped region, having a second conductive type opposite to the first conductive type, formed on the first well region, wherein the gate structure and the second doped region are disposed between the first and second electrodes, wherein the first electrodes are disposed outside the gate structures, each at a distance further from the second electrode than the gate structures.
