Abstract
The SOI lateral semiconductor device includes a semiconductor region of a first conductivity type, a buried oxide film layer in the semiconductor region, a thin active layer on the buried oxide film layer, an anode region in the thin active layer, and a drain layer contacting the buried oxide film layer for confining the minority carriers injected from the anode region to the thin active layer within the thin active layer and for forming a structure that sustains a high breakdown voltage. The SOI lateral semiconductor device can provide a high breakdown voltage and low switching losses using the thin buried oxide film, which can be formed by an implanted oxygen (SIMOX) method.
