Abstract:
A semiconductor device comprising:a wiring substrate which has a laminated glass fabric body made by laminating a plurality of glass fabrics and impregnating with resin, a covering resin layer on at least substantially all of one of surfaces of said laminated glass fabric body, and a plurality of pad electrodes formed on said resin layer, wherein said covering resin layer has a thickness from 1.5 to 2.5 times the depth of unevenness of the surface of said laminated glass fabric body on which said covering resin layer exists; and a semiconductor pellet disposed on said wiring substrate and having a plurality of projected electrodes, said projected electrodes being electrically coupled to said pad electrodes by pressing said projected electrodes to said pad electrodes while heating said wiring substrate and/or said semiconductor pellet, tip portions of said projected electrodes together with said pad electrodes plunge into said resin layer.
