DISPOSITIF A SEMICONDUCTEURS COMPORTANT UN BOITIER ET UNE EMBASE ISOLANTE, ET PROCEDE DE FABRICATION DE CE DISPOSITIF

摘要

It is an object of the present invention to obtain a power semiconductor device with small size and high reliability in power semiconductor devices having integral structure of case and external connection terminals. A dummy pad (42) having no electric connection with other parts is provided and a terminal end of a connecting wire (46) connecting by sequentially bonding an exposed surface of a connection electrode (43) and a bonding pad (41) of a semiconductor element (40) is bonded thereto. The semiconductor device can be miniaturized without deteriorating electric characteristics and reliability of the semiconductor elements.
