Abstract
A semiconductor device including a main region, a sense region, a separation region electrically isolating the main and sense region regions includes a first semiconductor layer positioned on the main surface of a semiconductor substrate, a plurality of main cells disposed in the main region, and a plurality of sense cells disposed in the sense region. Source regions of the main cell become conductive with a source electrode and source regions of the sense cell become conductive with a sense electrode. The separation region includes a plurality of second conductivity type separation body regions and a barrier region and is disposed within a first semiconductor layer and is disposed to abut on the surface of the first semiconductor layer.
