Abstract:
A semiconductor device comprising:a semiconductor chip having a mounting surface with electrodes mounted thereon; and a film having a gluing surface facing said mounting surface of said semiconductor chip and having a mounting surface for mounting to a circuit board, said mounting surface of said film being a surface opposite said gluing surface, said circuit board having connecting pads mounted thereon, wherein said film has on said mounting surface a wiring pattern formed thereon with connecting terminals connected to said connecting pads on said circuit board, said film is an anisotropically conductive film that exhibits conductivity at areas subjected to pressure between said wiring pattern and said electrodes of said semiconductor chip, said gluing surface of said film is attached solidly to said semiconductor chip with conductivity of said film being maintained by a hardening process of said film, and said mounting surface of said film and said wiring pattern are covered with an insulating film except for areas of said connecting terminals of said wiring pattern.
