Abstract:
1. A method for manufacturing an insulation structure for high temperature conditions comprising: preparing a substrate having a conductive pattern formed on at least one surface thereof for electrical connection of a device; depositing a metal selected from a group consisting of Al, Ti and Mg on the substrate with the conductive pattern formed thereon by PVD to form a metal deposition layer; oxidizing the metal deposition layer by anodization to form a metal oxide layer; applying a photosensitive film to the metal oxide layer, and exposing and developing the photosensitive film to form a plurality of photosensitive film patterns and exposing the metal oxide layer between the plurality of the photosensitive film patterns; and removing the metal oxide layer exposed between the plurality of the photosensitive film patterns by etching a surface of the substrate using the photosensitive film pattern as a mask, wherein
