Abstract

A coated fine metallic wire intended for use as a bonding wire in a semiconductor device, includes a fine metallic wire and an insulative layer which contains a pigment or dye which causes the insulative layer to absorb laser light at a high efficiency. The insulative layer is readily removable with a laser light, with no carbonized matter remaining on the fine wire and without damaging the fine wire.
