Abstract:
A method of manufacturing a semiconductor device, comprising the steps of:(a) providing a semiconductor chip having a plurality of salient electrodes formed by conductors including gold; (b) providing a wiring substrate, said wiring substrate comprising a thin film base formed by an insulator including an organic resin and a plurality of leads formed on said thin film base correspondingly to said plural salient electrodes; and (c) bonding said plural salient electrodes formed on said semiconductor chip respectively to said plural leads formed on said wiring substrate, wherein, in said wiring substrate provided in said step (b), the pitch of said plural salient electrodes is larger than the pitch of said leads at the portions corresponding respectively to the plural salient electrodes, and wherein said plural leads are fixed to said thin film base at their portions to be bonded to said salient electrodes.
