Abstract:
A semiconductor device comprising:a semiconductor chip having a main surface of a rectangular shape, said semiconductor chip having an integrated circuit and external terminals formed on said main surface, said main surface having a pair of longer edges extending in a first direction and a pair of shorter edges extending in a second direction which is different from said first direction;a power supply lead having an inner lead and an outer lead which is continuous with said inner lead, said inner lead of said power supply lead having a first portion and a second portion, said first portion of said power supply lead being disposed on said main surface and extending in said first direction, said second portion of said power supply lead extending from said first portion to said outer lead of said power supply lead;signal leads each having an inner lead and an outer lead which is continuous with said inner lead, each of said inner leads of said signal leads crossing one of said pair of longer edges and extending on said main surface, each of said inner leads of said signal leads having a first portion which is disposed on said main surface;first bonding wires electrically connecting first ones of said external terminals with said power supply lead;second bonding wires electrically connecting second ones of said external terminals with said first portions of said signal leads; anda resin member having a pair of longer sides extending in said first direction and a pair of shorter sides extending in said second direction, said resin member sealing said semiconductor chip, said inner lead of said power supply lead, the inner leads of said signal leads and said first and second bonding wires, said outer leads of said power supply lead protruding outwardly from one of said pair of longer sides adjacent to said one of the longer edges of said main surface of said semiconductor chip, and said outer leads of said signal leads also protruding outwardly from said one of said pair of longer sides of the resin member,wherein said external terminals connected to said first and second bonding wires and said first portions of said signal leads are arranged between said first portion of said power supply lead and said one of the longer edges of said main surface of said semiconductor chip.
