According to a semiconductor device (), a first switching active element () of a normally-on type and a second switching active element () of a normally-off type are cascode-connected to each other. This causes an electric current path to be formed. The first and second switching active elements () are provided and connected so that loop area of the electric current path is a minimum area in a plan view of the semiconductor device ().

Semiconductor device and electronic apparatus

A semiconductor device comprising: a substrate; first and second interconnection patterns respectively provided on upper and lower surfaces of the substrate; a through-hole electrode extending through the substrate for electrically connecting the first and second interconnection patterns; a semiconductor chip provided on the upper surface of the substrate and electrically connected to the first interconnection pattern; and a resist film covering the second interconnection pattern; the second interconnection pattern comprising a generally round land and a lead interconnection portion extending from the land, the resist film having an opening formed therein for exposing the entire land, the opening having a curved edge surrounding a peripheral edge of the land and a linear edge linearly extending along a boundary between the land and the lead interconnection portion, the exposed land having a solder ball as an external terminal thereon.
