Abstract:
A conductive pattern film substrate and manufacturing method for combining two anisotropic materials, namely a patterned body and a film layer, without assistance from an intermediate layer. The method includes producing a thermal spraying source for performing a heating operation on a film material to prepare the film material for thermal spraying or semi-thermal spraying and thereby decompose the film material into film particles; and spraying the film particles to a pattern layer disposed on the body and having the pattern by the thermal spraying source to form the film layer having the film particle on the pattern layer, thereby enabling the body to embody electrical characteristics of the pattern.
