Claim Text:
1. A semiconductor device, comprising: a first-conductivity-type semiconductor source region; a second-conductivity-type semiconductor body region; a gate electrode, which is capacitively coupled to invert a horizontal portion of said body region; a semiconductor drift region which includes both first-conductivity-type and second-conductivity-type semiconductor stripes in parallel; a trench, containing immobile electrostatic charge which is capacitively coupled to invert parts of said second-conductivity-type stripes; and a first-conductivity-type semiconductor drain region; wherein said body region is interposed between said source region and said drift region; and wherein said first-conductivity-type and second-conductivity-type semiconductor stripes are each laterally interposed between said body region and said drain region; whereby, in the ON state, majority carriers flow both through said first-conductivity-type and said second-conductivity-type stripes in parallel.
