Abstract:
1. A method of forming a conductive thin film pattern, comprising: a first step of forming an underfilm made of a conductor on a substrate; a second step of selectively forming a first resist frame on the underfilm; a third step of forming a first conductive layer pattern by selective plating growth using the first resist frame as a mask and using the underfilm as an electrode film; a fourth step of forming an intermediate conductive layer so as to cover the first resist frame and the first conductive layer pattern; a fifth step of selectively forming a second resist frame on the intermediate conductive layer in a position corresponding to the first resist frame; a sixth step of forming a second conductive layer pattern by selective plating growth using the second resist frame as a mask and using the intermediate conductive layer as an electrode film; and a seventh step of completing formation of the conductive thin film pattern by removing the first and second resist frames, the intermediate conductive layer in a position sandwiched by the resist frames, and the underfilm.
