Abstract:
A lateral thin-film Silicon-On-Insulator (SOI) device comprising a semiconductor substrate, a buried insulating layer on said substrate, and a lateral MOS device in an SOI layer on said buried insulating layer and having a source region of a first conductivity type formed in a body region of a second conductivity type opposite to that of the first, a lateral drift region of said first conductivity type adjacent said body region, a drain region of said first conductivity type and laterally spaced apart from said body region by said lateral drift region, and a gate electrode over a part of said body region in which a channel region is formed during operation and over at least a part of said lateral drift region adjacent said body region, said gate electrode being insulated from said body region and drift region by an insulation region, further comprising means in said SOI layer for depleting a portion of said drift region adjacent said body region in a lateral direction during operation.
