Abstract:
A method for forming power semiconductor device is provided. The power semiconductor device includes a substrate having a device region and a surrounding termination region; and at least a power device formed in the device region of the substrate. The power semiconductor substrate also includes a termination structure having a plurality of semiconductor plugs formed in a first surface of the termination region of the substrate. Wherein the plurality of the semiconductor plugs are formed in a plurality of ring trenches formed in the first surface of the substrate in the termination regions, with a semiconductor plug formed in each of the plurality of ring trenches.

Claim (Index 1):
A method for fabricating a power semiconductor device, comprising:\n providing a substrate having a device region and a surrounding termination region; forming at least one power device in the device region; forming a plurality of ring trenches in a first surface of the substrate in the termination region; and forming a semiconductor plug in each of the plurality of ring trenches, wherein the plurality of semiconductor plugs and the substrate form a termination structure of the power semiconductor device to insulate the at least one power device in the device region.
