Abstract:
A resin-encapsulated semiconductor device, comprising:a die pad; a semiconductor chip mounted on the die pad; a first lead including a first bonding pad provided on an upper surface of the first lead and a first land provided on a lower surface of the first lead; a second lead including a second bonding pad provided on an upper surface of the second lead and a second land provided on a lower surface of the second lead; a third lead including a third bonding pad provided on an upper surface of the third lead and a third land provided on a lower surface of the third lead; thin metal wires each connecting the bonding pad of each lead to a portion of the semiconductor chip; and an encapsulation resin for encapsulating the semiconductor chip, the leads, the thin metal wires and the die pad, wherein the first lead and the third lead are separated from each other, with one end of the first lead being exposed on a surface of the encapsulation resin and both ends of the third lead being in the encapsulation resin, and a second row composed of the second bonding pads is formed between a first row composed of the first bonding pads and a third row composed of the third bonding pads.
