IPC: H01L21/60
Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To improve moisture resistance by eliminating pealing between a resin for outside sealing and an inner lead in a resin sealed semiconductor device. SOLUTION: A putting resin layer 2 softer than a resin for outside sealing is preliminarily formed in an inner lead 3 of a lead frame with an interposed part 1 with which a bonding wire is connected. After the wire bonding, the resin layer 2 is heated. The resin layer 2 is softened and flowed out so that the part of the bonding connection and the side face and back face of the inner lead can be covered.
