Abstract:
A method of manufacturing a semiconductor device, comprising the steps of:covering an interconnection having a bonding pad with an insulating film; forming a photoresist film having a first opening above the bonding pad on the insulating film; forming a second opening in the insulating film below the first opening by anisotropic etching using the photoresist film as a mask; removing a metal polymer film and an organic polymer film formed on an inner side surface of the second opening, said removing step consisting of: removing, with an amino group of an amine-based organic solvent, subsequent to the anisotropic etching, the metal polymer film formed on an inner side surface of the second opening by the anisotropic etching and the photoresist film while simultaneously removing said photoresist film with an organic solvent component of said amine-based organic solvent; removing, with an oxygen plasma, the organic polymer film formed on the inner side surface of the second opening by the anisotropic etching after removal with the amine-based organic solvent; and bonding a wire to the bonding pad after removal with the oxygen plasma.
