The present invention provides a semiconductor device, a fabrication method therefor, and a film fabrication method, the semiconductor device including a first substrate (e.g., a semiconductor chip), an anisotropic conductive film that is provided on the first substrate and has a wiring pattern having at least a portion providing conduction through the anisotropic conductive film, and a second substrate (semiconductor chip) provided on the anisotropic conductive film and coupled to the first substrate via the portion providing conduction through the anisotropic conductive film. According to the present invention, it is possible to provide a semiconductor device, a fabrication method therefor, and a film fabrication method, by which production costs can be reduced in electrically coupling different positions in upper and lower substrates.
