Abstract
A method of manufacturing fine pattern of the invention comprises (a) a step of manufacturing a master substrate having a film of precious metal or an alloy thereof formed as an insoluble electrode on the electrode, (b) a step of forming a fine pattern film on the insoluble electrode with anion type electro-deposition, and (c) a step of exfoliating and transferring the fine pattern film onto another substrate. Another method of manufacturing fine pattern further includes a step of manufacturing a master substrate, of which a surface is provided with at least a repeatedly reproducible sacrificial electrode. Still another method of manufacturing fine pattern includes a step of forming a pattern electrode on a conductive substrate by electro-forming, and transferring the electrode onto another substrate. Yet another method of manufacturing fine pattern includes a structure wherein a transparent section is provided in a portion of a master substrate in order to facilitate a positional alignment. The invention provides reliable and accurate mass production of fine-line and high-density films of fine pattern having good transfer ability and durability at low cost. A fine-line and high-density printed circuit board can be made at low cost with the methods of manufacturing fine pattern as disclosed above.
