Patent ID: 7966720

Claim:
A method of manufacturing an element substrate comprising: (a) forming a release layer on a first support substrate; (b) forming a metal layer having a predetermined pattern on the release layer; (c) applying a sol-gel solution including a material for an inorganic substrate to the first support substrate; (d) removing a solvent from the sol-gel solution by heat treatment to form the inorganic substrate; and (e) removing the metal layer from the first support substrate by decomposing the release layer to transfer the metal layer to the inorganic substrate, wherein the metal layer is formed by electroless plating in the step (b); wherein the first support substrate is immersed in a surfactant solution in the step (a) to form a surfactant layer as the release layer; and wherein the step (b) includes: forming a catalyst layer on the release layer by immersing the first support substrate in a catalyst solution; and depositing a metal layer on the catalyst layer by immersing the first support substrate in an electroless plating solution.
