Title: Semiconductor device with heat sink plate
Inventor: YOKOYAMA RIYOUICHI
IPC: H01L23/29
Filed: 1983-08-01
Abstract: PURPOSE:To enhance the fixing strength by forming part of a through hole for enhancing the fixing strength to the resin of a heat sink plate in a flared shape. CONSTITUTION:In a semiconductor device in which the main portion including a pellet of a heat sink plate is sealed with resin to expose the surface opposed to the main surface, to which the pellet is bonded, a through hole having a stepwise difference is formed at the plate, part of the sealing resin is filled in the hole, thereby enhancing the fixing strength of the resin of the plate. The hole is obtained by forming a straight through hole 5 at the plate 2, then collapsing it by a punch 8 having a diameter larger than the hole 5 and a conical taper at the end. Since the conical taper is formed at the end of the punch 8, a burr for reducing the diameter of the resin does not occur at the step of the hole. Accordingly, the fixing strength of the resin of the plate can be enhanced.
