摘要：
A semiconductor device including a semiconductor layer that includes an active region, semiconductor elements that are formed using the active region, connection regions that are obtained by metalizing parts of the semiconductor layer in an island shape isolated from the active region, an insulation film that is formed to cover one main surface side of the semiconductor layer, electrodes that are disposed to face the semiconductor elements and the connection regions via the insulation film, and contacts that penetrate through the insulation film to be selectively formed in portions according to necessity among portions that connect the semiconductor elements or the connection regions to the electrodes.
