Claim Text:
1. A semiconductor device comprising: a semiconductor chip having an upper surface and a lower surface; an island having a lower surface, and an upper surface to which the semiconductor chip is bonded; a plurality of leads arranged around the island; for each lead, a bonding wire extending between the upper surface of the semiconductor chip and an upper surface of the lead; and a resin package sealing the semiconductor chip, the island, the plurality of leads and the bonding wires; wherein the leads on a lower surface of the resin package are adapted to allow the semiconductor device to be surface mounted; wherein, in bottom plan view, the island has an area defined by four sides, each of which is not parallel to any sides of the resin package, and for each side of said area of the island the angle between the side of the island and any of the sides of the resin package is less than a perpendicular angle; wherein at least two of the plurality of leads are arranged at respective corners of the semiconductor device in bottom plan view; wherein each of the plurality of leads has a side facing a respective one of the four sides of the area of the island, the side of the lead and the respective side of the island forming a facing pair of sides; and wherein one of the facing pairs includes a recess such that at least a portion of the respective side of the area of the island and at least a portion of the recess are non-parallel.
