Abstract:
A resin-sealed semiconductor device, comprising:a semiconductor chip having a circuit surface on which a plurality of electrodes are formed,a plurality of leads which are arranged side-by-side with gaps therebetween on said semiconductor chip in such a manner that distal ends of said leads overlap said semiconductor chip and are respectively electrically connected to said electrodes;a lead fixing resin layer between said semiconductor chip and said leads fixing said leads to said semiconductor chip; anda sealing resin layer coating the distal ends of said leads and said semiconductor chip,wherein both said lead fixing resin layer and said sealing resin layer contain filler, the diameter of the filler contained in said lead fixing resin layer being signaler than the diameter of filler contained in said sealing resin layer;wherein said lead fixing resin layer consists essentially of a lead fixing resin and the filler;wherein said lead fixing resin layer is free of an adhesive layer other than said lead fixing resin; andwherein said lead fixing resin layer extends continuously from the respective distal ends of said leads to at least an outer periphery of the chip.
