Abstract:
1. A semiconductor device manufacturing method comprising: (a) bonding a first surface of a metal plate to a substrate; (b) forming a plurality of metal posts that are arranged in vertical and lateral directions in a plan view and include a first metal post and a second metal post, by partially etching the metal plate bonded to the substrate from a second surface of the metal plate; (c) fixing an integrated circuit element to the second surface of the first metal post; (d) coupling the second metal post and a pad terminal of the integrated circuit element via a conductive material; (e) resin-sealing the integrated circuit element, the metal posts, and the conductive material by providing a resin onto the substrate; (f) removing the substrate from the resin and the first surfaces of the metal posts sealed using the resin; and (g) forming the metal posts partway by partially half-etching the metal plate from the first surface prior to the bonding of the first surface of the metal plate, wherein in the forming of the plurality of the metal posts, the metal plate is penetrated by etching the half-etched metal plate from the second surface.
