Abstract:
1. A metal-insulator-semiconductor device comprising: a first drain region; a body region disposed on a first surface of said first drain region; a gate region extending through said body region and partially into said first drain region; a source region disposed between a first portion of said body region and a first portion of said gate region; a first insulative layer disposed between said source region and said first portion of said gate region and between said body region and a second portion of said gate region, wherein a thickness of said first insulative layer is in the range of approximately 100 to 1000 Å; and a second insulative layer disposed at least partially between a first portion of said first drain region and a third portion of said gate region and adjacent to said first insulative layer, wherein a thickness of said second insulative layer is in the range of approximate 0.1 to 0.3 μm, wherein said second insulative layer is not formed by oxidizing said first drain region and wherein said second insulative layer does not introduce substantial stress in said first drain region.
