Abstract:
1. A method for forming a high-resolution pattern having a desired thickness and a high aspect ratio using a dry film resist by selectively removing the dry film resist attached onto a substrate by exposure to light and depositing a functional material into a region from which the dry film resist is removed, the method comprising: a dry film resist-attaching step (S an exposure step (S a pattern template-forming step (S a deposition step (S wherein the dry film resist comprises: a protective layer for preventing contamination from occurring during processing; a photosensitive layer sensitive to the focusable energy beam; a light shielding layer for preventing the focusable energy beam from being transferred below the dry film resist; and one of a surfactant layer, a polymer layer, or a surfactant-containing polymer layer for controlling wettability such as hydrophobicity or hydrophilicity with the functional material.
