Abstract
PURPOSE: To provide a carrier tape for use in IC which is designed to lighten or decrease burdens and costs on the part of IC undertakers by providing in advance a bonding bupm at the tip of a finger of the carrier tape.
CONSTITUTION: Along each side of a tape 1, a row of splocket perforations is provided. The surface of the tape at its central part, i.e., excluding the perforation areas, is coated with a bonding agent, and a separator is adhered to the coated surface. Then device holes 6 and window holes 7 are provided at predetermined intervals. Thereupon, the separator is peeled off the surface and, in its place, a prepared tapelike piece of conductor foil 5 is adhered by lamination, followed by smoothening the foil surface. The smoothened surface of conductor foil 5 is coated with a photoresist, and the coated surface is exposed tolight, so that a low melting- point metal being material for bump formation is adsorbed on conductor foil 5 at a predetermined place. Then, the formation of finger patterns is carried out, to finally obtain the desired carrier tape for use in IC.
