Abstract:
1. A resin sealing type semiconductor device comprising: a lead frame comprising an island, a wire-bonding portion located in the island, a first extension portion extending straight from the island in a first direction in plan view of the semiconductor device and a second extension portion extending straight from the island in a second direction in the plan view of the semiconductor device, the first direction being different from the second direction so that the first and second directions are substantially perpendicular to each other; a semiconductor die die-bonded to the island and wire-bonded to the wire-bonding portion using a wire comprising aluminum or copper; and a resin package sealing the lead frame and the semiconductor die, wherein one side edge of the resin package extends in the first direction, and another side edge of the resin package extends in the second direction.
