Abstract:
1. A method for manufacturing an insulated conductive pattern, the method comprising: a) forming a conductive film on a substrate; b) forming an insulation layer pattern on the conductive film; c) forming a conductive pattern by etching the conductive film by using the insulation layer pattern as a mask; and d) reforming the insulation layer pattern for covering the conductive pattern, wherein in step c), a taper angle of the conductive pattern is more than 0° to less than 90°, wherein a taper angle of the insulation layer pattern is more than 0° to less than 90°, wherein the insulation layer pattern is not removed so that the conductive pattern is insulated, wherein in step c), an etching time of the conductive film is a just-etching time to a time that is delayed by 2000% as compared to the just-etching time, wherein a line width of the conductive pattern is 100 micrometers or less, and wherein the insulation layer pattern includes one or more polymer selected from imide-based polymer, bisphenol-based polymer, epoxy-based polymer, acryl-based polymer, ester-based polymer, and novolac-based polymer; or a combination or copolymer of two or more selected from imide-based monomer, bisphenol-based monomer, epoxy-based monomer, acryl-based monomer, and ester-based monomer.
