| description | PROBLEM TO BE SOLVED: To enhance productivity, bonding stability and general purpose properties by shortening the time required for production at the time of flip-chip bonding where a wiring pattern on a substrate is bonded with a semiconductor element through a metallic material, e.g. solder. SOLUTION: The wiring material 1 comprises an insulating film 2 of resin material for die bonding, e.g. epoxy or polyimide, and a plurality of metal wires 3 of wiring metal, e.g. solder or gold, arranged in parallel while being supported by the insulating film 2. The metal wires 3 are exposed, by about 1/5-1/4 of the diameter thereof, from the surface and rear of the insulating film 2. The wiring material 1 is formed into a sheet or a ribbon and used while being cut freely in the lateral or longitudinal direction to include an arbitrary number and length of the metal wires 3. |
