METHOD FOR FABRICATING AN ELECTRONIC CIRCUIT DEVICE

摘要

The present invention is to provide a method for manufacturing a circuit pattern-provided transparent substrate having a circuit pattern which is free from pattern peeling and remaining of resist and has good pattern precision and which does not cause disconnection when used as an electrode of an electron circuit or the like. The invention relates to a method for manufacturing a circuit pattern-provided substrate, in which a desired circuit pattern comprising a thin film layer is formed on a substrate, which method includes: a step of forming a resist layer on the substrate; a step of forming an opening of a shape corresponding to a desired circuit pattern in the resist layer; a step of forming a thin film layer; and a step of peeling off the resist layer and the thin film layer formed on the resist layer, wherein the cross-sectional shape in the opening of the resist layer has a cross-sectional shape of eaves type having a space at a boundary part between the resist layer and the substrate, the height and the width of the space are determined such that when the thin film layer is formed in the thin film layer forming step, an end of the thin film layer formed on the substrate in the opening does not go up onto a foot of the resist layer.
