Abstract:
A method for fabricating semiconductor devices including resin packages sealing semiconductor elements and external connection terminals respectively resin projections formed on the resin packages and metallic film parts provided to the resin projections, said method comprising the steps of:(a) mounting the semiconductor elements to a lead frame having recess portions located in positions corresponding to positions of the resin projections, metallic film parts being provided in the recess portions;(b) electrically connecting the semiconductor elements to the metallic film parts;(c) forming the resin packages that seal the semiconductor elements and gate portions integrally formed with the resin packages;(d) etching the lead frame so that the resin packages are separated from the lead frame together with the metallic film parts; and(e) removing the gate portions from the resin packages,the resin packages being attached to an adhesive tape provided to a frame and being used as a carrier in the step (d).
