Abstract:
1. A method for forming a conductive membrane, comprising: providing a substrate; coating a photoresist agent with a sulfonic group on said substrate; performing a lithographic process so as to form at least one specifically patterned photoresist layer with a crosslinking structure on said substrate; modifying a first aniline oligomer so as to form a second aniline oligomer with a sulfonic group; ionizing said second aniline oligomer to make said second aniline oligomer to have a group containing nitrogen atoms and carrying a positive charge and a sulfonic group carrying a negative charge; ionizing said at least one specifically patterned photoresist layer on said substrate to make said photoresist layer to have a sulfonic group carrying a negative charge; and performing a membrane fabricating process to form a conductive membrane on said at least one specifically patterned photoresist layer by bonding said group containing nitrogen atoms and carrying a positive charge of said second aniline oligomer to said sulfonic group of said photoresist layer.
