Abstract
PURPOSE: To accurately and readily form element holes and sprocket holes at a carrier tape for a semiconductor device by coating photosensitive resin on a metallic foil, perforating element holes at the resin tape and etching the metallic foil.
CONSTITUTION: Photo-setting varnish 2 is coated on a metallic foil such as, for example, copper foil tape 1. Then, light is irradiated through a mask 2 formed in advance with pattern to the metallic foil. This foil is then immersed in a solvent to dissolve the portions where light is not irradiated to thereby perforate predetermined semiconductor element connecting holes 4A and tape position feeding sprocket holes 4B at the varnish. Then, when the varnish is completely hardened, a carrier tape can be thus obtained. Then, the copper foil 1 is etched to form a conductor pattern 5. Thus, it can accurately and readily form the element holes 4A and sprocket holes 4B with superior mechanical strength and heat insulation.
