Abstract
A resin-sealed semiconductor device comprising a semiconductor chip having pad electrodes formed on a circuit forming surface in the interior of the main surface and inner leads cemented to the semiconductor chip through an insulator for electric insulation such that ends of the inner leads reach the edge of the circuit forming surface of the semiconductor chip, wherein common conductors, which are connected with at least one of power supplying inner leads and/or grounding inner leads, and at least one of the inner leads are coupled on the semiconductor chip, and wherein the configuration of the common conductors and the inner leads coupled together is virtually L-shaped, T-shaped, -shaped, or cross-shaped.
Claims5
A rectangular resin-sealed semiconductor having four sides, two opposite sides of which are short sides and the other sides are longer relative to said short sides, comprising:
- a semiconductor chip having pad electrodes formed on a circuit forming surface in the interior of the main surface;
- and
- a plurality of inner leads cemented to said semiconductor chip through an insulator for electric insulation such that ends of said inner leads reach the edge of the circuit forming surface of said semiconductor chip;
- wherein
- common conductors, which are connected with at least one of power supplying inner leads, and/or grounding inner leads, and at least one of said inner leads are coupled on said semiconductor chip, and said common conductors engage at least one support bar extending to the middle of one of said short sides.
