Abstract:
This invention discloses a semiconductor power device disposed in a semiconductor substrate. The semiconductor power device comprises a plurality of trenches each having a trench endpoint with an endpoint sidewall perpendicular to a longitudinal direction of the trench and extends vertically downward from a top surface to a trench bottom surface. The semiconductor power device further includes a trench bottom dopant region disposed below the trench bottom surface and a sidewall dopant region disposed along the endpoint sidewall wherein the sidewall dopant region extends vertically downward along the endpoint sidewall of the trench to reach the trench bottom dopant region and pick-up the trench bottom dopant region to the top surface of the semiconductor substrate.

Claim (Index 5):
The method of  claim 1  wherein:\n the step etching the semiconductor substrate through the patterned hard mask to form a plurality of trenches in the top portion of the semiconductor further comprising a step of forming each trench to extend between two pre-designated locations with the trenches have different lengths and wherein the trench endpoints are distributed at the designated locations on the entire surface of the semiconductor substrate.
