Abstract
Leads near a die pad of a lead frame for a semiconductor device include terminal leads in a pattern on an insulating resin layer. The inner ends of the terminal leads are connected with gold wires to electrode pads of a semiconductor chip, and the outer ends of the terminal leads are also connected with gold wires to inner lead portions of the leads. Wide ground pads are provided which extend from the inner lead portions to the die pad. Ground electrodes on the semiconductor chip are connected with wires to the ground pads to which the insulating resin layer is bonded.
