Abstract:
A method for producing a semiconductor device in which an active element formed on a substrate is connected to a heat sink member of a package accommodating said active element, comprising the steps of:(a) forming a gate electrode on said substrate; (b) forming a first insulating film having holes provided in the substrate at positions of a drain electrode and a source electrode respectively; (c) forming said drain electrode and said source electrode on said substrate; (d) providing on said package an insulating member at a position facing the drain electrode of said active element; (e) providing a metal protuberance on said package in register with the source electrode of said active element; (f) bonding said active element and the package so that said source electrode of said active element and the metal protuberance of said package contact each other and so that the drain electrode and the insulating member of said package contact each other.
