Abstract:
1. A method for forming a resist pattern on a substrate comprising a conductive polymer, the method sequentially comprising: forming a photoresist film on said substrate; prebaking, by heating, said photoresist film; exposing a resist film from said prebaking to leave at least a portion of a surface of said resist film arranged on the surface of a conductive layer in the surface of said resist film unexposed; and removing the exposed part through said exposing with a developing solution, to expose at least a portion of said substrate comprising said conductive polymer, wherein: said conductive polymer is a polythiophen or a polypyrrole; a positive type photoresist is developed with said developing solution, which comprises: i) a component comprising at least one selected from the group consisting of phosphoric acid, glycine, and aspartic acid, ii) an alkaline agent comprising KOH and K said developing solution is an alkaline solution.
