Patent ID: 7443012

Claim:
A semiconductor device, comprising: a package body having an upper surfaces, a bottom surface opposite to the upper surface and a package side surface being located between the upper and the bottom surfaces; a plurality of conductive members, each having a first surface, a second surface opposite to the first surface and a side surface being located between the first and second surfaces, wherein all of the first and side surfaces are contained within the package body, and wherein the second surface is exposed from the package body and is coplanar with the bottom surface of the package body; an insulating member, which is formed on the first surfaces of some of the conductive members; a semiconductor chip having a terminal, which is formed on the insulating member; and a bonding wire extending the terminal and the first surface of one of the conductive members, which is not just below the semiconductor chip, wherein a width of the package body between the package side surface and the side surface of one of the conductive members at its first surface is getting wider gradually towards the bottom surface of the package body.
