Abstract:
1. A semiconductor device in which a semiconductor substrate having a high breakdown voltage transistor formed thereon is covered with a sealing resin, the semiconductor device comprising: a source region and a drain region formed in a main surface portion of the semiconductor substrate; a gate insulating film formed on the drain region and having an end extended to overlap the source region; a gate electrode formed on the gate insulating film; a source electrode connected to the source region; a drain electrode connected to the drain region; an inter-layer film for covering the gate electrode and electrically insulating the gate electrode, the source electrode and the drain electrode from one another; a passivation film for covering an entire surface of a semiconductor substrate body; a first opening formed in the passivation film; and a sealing resin formed on the passivation film; wherein: the first opening is formed on at least either one of the source electrode and the drain electrode; and the sealing resin fills the first opening and is in direct contact with at least either one of the source electrode and the drain electrode.
