Abstract

PURPOSE: To increase the yield rate and to make assembling quick, by preventing the deformation of leads through the avoidance of the free ends of leads for tape.
CONSTITUTION: Copper foil is attached to the polyimide resin film 11, the copper foil is etched in the form that the window holes 13,13',13"... placed at the part corresponding to the junction of the semiconductor element 12 are bridged 14a,14a', 14a", forming the leads 14,14',14". The electrode pads 12a,12a',12a"... of the element 12 are assembled by bonding the bridged parts. Thus, no lead play end is present at the tape, and the leads cause no deformation because the bonded parts of leads are fixed on the film for the ends, and assembling can rapidly be made.
