IPC: H01L23/48
Filed: 1987-11-20
Abstract: PURPOSE:To save trouble of application of insulating resin, etc., by avoiding the use of a frame exposure part by molding the title device by sticking an insulator plate to both surfaces of part of a frame or pre-molding the former plate on the latter surfaces and keeping unchanged a distance between the frame and the inner surface of a mold by supporting the plate surface of the insulator with a pin in the mold. CONSTITUTION:An insulating plate 8 is sticked to or fixedly mounted on the upper and lower surfaces of a tip end part 2 of a lead frame so as to cover those surfaces. The tip end part 2 of the lead frame is horizontally supported in a mold by a push pin 9 via the insulating plate 8 so as to keep unchanged a distance between the bottom of the frame and the mold. In this situation, resin is introduced into a cavity 7 from a gate 10 for resin-molding to completely surround the frame 1 and a chip 4. The part of the lead frame pushed by the push pin 9 is fully molded by the introduced resin because the surface of the frame 1 is covered with the insulating plate 8, making unnecessary any bonding work thereafter. Additionally, the thickness of the resin on the lower surface of the frame 1 can be kept uniform, thereby assuring uniform thermal resistance.
