Patent ID: 7807498

Claim:
A semiconductor device, comprising: a plurality of metal posts that are aligned in a longitudinal direction and a lateral direction in plan view, each of the plurality of metal posts having a first surface and a second surface facing an opposite direction to the first surface, the plurality of metal posts having a first metal post and a second metal post; a bare chip that is fixed on the first surface of the first metal post; a first conductive member that couples the first surface of the second metal post to a pad terminal of the bare chip; and a first resin that seals the bare chip, the first conductive member, and a part of the plurality of metal posts, wherein the plurality of metal posts are in an identical configuration in plan view; wherein each of the plurality of metal posts are electrically disconnected from each other; wherein the second surface of the plurality of metal posts is exposed from the first resin: wherein a side surface of each of the plurality of metal posts is cross-sectionally curved, and wherein each of the plurality of metal posts are made from a homogenous material comprising copper or alloy containing the majority atomic percentage of copper.
