Abstract
A semiconductor integrated circuit device having a SOI structure which can prevent a deterioration in the breakdown voltage of a transistor without damaging integration, and a method for manufacturing the semiconductor integrated circuit device are obtained. An embedded oxide film is not formed over the whole face of a P type silicon layer but has an opening in a region which is placed below a gate electrode. The opening is filled in to form a penetration P layer. Accordingly, a SOI layer is electrically connected to the P type silicon layer through the penetration P layer. The plane position and shape of the gate electrode conform to those of the penetration P layer.
