Abstract
A lateral SOI device may include a semiconductor channel region connected to a drain region by a drift region. An insulation region on the drift layer is positioned between the channel region and the drain region. Permanent charges may be embedded in the insulation region sufficient to cause inversion in the insulation region. The semiconductor layer also overlies a global insulation layer, and permanent charges are preferably embedded in at least selected areas of this insulation layer too.
