Patent ID: 8659117

Claim:
A Schottky diode comprising: a drift region of a first conductivity type; a lightly doped silicon region of the first conductivity type disposed in the drift region; a conductor layer disposed on and in contact with the lightly doped silicon region, the conductor layer forming a Schottky contact with the lightly doped silicon region; a highly doped silicon region of the first conductivity type disposed in the drift region, the highly doped silicon region being spaced from the lightly doped silicon region in the drift region such that upon biasing the Schottky diode in a conducting state, a current flows between the lightly doped silicon region and the highly doped silicon region through the drift region; and a trench extending into the drift region perpendicular to a direction of the current flow, the trench including a dielectric layer disposed on at least a portion of a sidewall of the trench and at least one conductive electrode disposed within the dielectric layer.
