Abstract

A semiconductor device according to the present invention has reduced inductance on a power supply line, a grounding line, and signal lines. In this invention, to reduce the length of the power supply connection and that of the grounding connection, a power supply metal post and a grounding metal post are respectively provided on a power supply lead of a semiconductor chip and grounding lead of the semiconductor chip perpendicular to the leads. The metal posts protrude from the resin encapsulating the chip and are connected to lands or a conductive circuit pattern on a printed circuit board. Furthermore, a planar conductor commonly connecting the power supply or grounding potentials is provided.
