Abstract:
Power devices using refilled trenches with permanent charge at or near their sidewalls. These trenches extend vertically into a drift region.

Claim (Index 22):
A semiconductor power device, comprising:\n a current-controlling structure at a first surface of a semiconductor mass; a semiconductive drift region extending down into said semiconductor mass; said current-controlling structure and said drift region being jointly connected in series between a first source/drain region at said first surface, and a second source/drain region at a second surface of said semiconductor mass; and trenches extending down through said drift region into said semiconductor mass, at least some ones of said trenches being at least partially filled with a trench-filling material which is not an insulator, and which is electrically connected to said second source/drain region; said trenches and said current-controlling structure having completely independent lateral alignment; wherein permanent electrostatic charge is present at sidewalls of said trenches.
