Abstract
A semiconductor device including a semiconductor substrate having a main surface. An insulating film is formed on the main surface of the semiconductor substrate. A semiconductor layer is placed on the insulating film. Side insulating regions extending from a surface of the semiconductor layer to the insulating film divide the semiconductor layer into element regions. The element regions are isolated from each other by the side insulating regions and the insulating film. The semiconductor substrate has a resistivity of 1.5 .OMEGA.cm or lower. A voltage at the semiconductor substrate is set to a given voltage.
