Abstract:
1. A semiconductor device, comprising: a trench-junction-barrier Schottky diode; and a PN diode integrally formed with the Schottky diode, wherein the PN diode is configured to function as a clamping element, and wherein the breakdown voltage of the PN diode is lower than the breakdown voltage of the Schottky diode; wherein, for breakdown voltages on the order of magnitude of several 10 wherein the semiconductor device includes: an n+ substrate; an n-layer provided on the n+ substrate; a plurality of trenches provided exclusively within the n-layer, wherein the trenches are filled with a p-doped material to form p-doped regions; and two contact layers provided for the n+ substrate and the n-layer, wherein the two contact layers cover the entire surfaces of the front and back sides of the semiconductor device.
