An electrically conductive base wire is coated with an insulating film of a polymeric material such as aromatic polyester, polyimide, polyether ether ketone, polyamide, polysulfone, or liquid crystalline polymer. The obtained insulator-coated bonding wire is characterized in that no crack develops in the insulation film when an impact of 1cm.gf is given thereto using a falling weight. Further, a method of producing this wire and a semiconductor device using the wire are disclosed. |
