Abstract:
A method of manufacturing a bump-attached tape carrier, which comprises the steps of;forming a first photosensitive resin layer on a metal foil of a laminate body comprising an insulating film and the metal foil;forming a first resin pattern for forming a circuit by performing a patterning of said first photosensitive resin layer;forming a metallic pattern on said metal foil exposed out of said first resin pattern by performing a first electroplating;forming a second photosensitive resin layer onto an overall surface including said metal pattern after removing said first resin pattern;forming a second resin pattern for forming metal bumps by performing a patterning of said second photosensitive resin layer;forming said metal bumps on said metallic pattern exposed out of said second resin pattern by performing a second electroplating;removing said second resin pattern; andforming a metal foil pattern by selectively removing said metal foil with said metallic pattern being employed as a mask.
