Abstract:
A semiconductor device can include: a substrate having a semiconductor material; a plurality of semiconductor layers of a first conductivity type, and being sequentially stacked on the substrate, where a doping concentration of the semiconductor layers successively increases from bottom to top; a trench that extends from the surface of a topmost semiconductor layer into a bottommost semiconductor layer of the semiconductor layers; a plurality of field plates that correspond to the semiconductor layers, each field plate being located in a portion of the trench that corresponds to one of the semiconductor layers; and a trench pad located in a bottom and a sidewall of the trench, and being filled each space between two adjacent field plates, where the thickness of the trench pad between each field plate and corresponding semiconductor layer sequentially decreases from the bottom to the top.

Claim (Index 5):
The semiconductor device of  claim 1 , wherein each semiconductor layer is depleted by a corresponding of said field plates and trench pads located therein.
