Abstract:
A method for manufacturing a resin sealed semiconductor device, comprising the steps of:forming a lead frame including an element mounting section mounted with a semiconductor element and a lead section having supporting means of said element mounting section and a plurality of leads, said element mounting section being formed such that a difference in level between said element mounting section and said lead section is caused by depressing said supporting means and corresponds to a thickness of said semiconductor element, and said element mounting section being formed so as to have a plurality of resin circulating holes uniformly formed around said semiconductor element and heat conducting paths formed between said plurality of resin circulating holes;electrically connecting each of electrodes of said semiconductor element with a corresponding one end portion of each lead of a tape carrier;mounting said semiconductor element on said element mounting section, said semiconductor element being fixed onto said element mounting section by electrically connecting each of the plurality of leads of said lead section and another end portion of said each lead of the tape carrier which is formed by cutting an outer lead forming portion of said tape carrier; andresin-sealing said semiconductor element, said element mounting section, part of said lead section, and said tape carrier using a mold, a fluid resin being injected along one of said supporting means of said element mounting section and flowing through said plurality of circulating holes, thus filling said mold with the fluid resin.
