Abstract:
A method for manufacturing an infrared ray sensor for a bolometer in which a temperature of said bolometer is varied by absorbing an incident light ray of an infrared ray, and a signal of radiation intensity of the infrared ray is read-out by changing an electrical resistance value in dependency upon temperature variation, comprising the steps of:forming a bridge structure body, a resistive element film for the bolometer, and a protection film via a space on a substrate, the protection film being placed on a surface including the resistive element film; placing the bridge structure body, the resistive element film and the protection film into a solution formed by dissolving metal organic compound into solvent; applying and drying the solution; irradiating the dried solution with a laser ray having a wavelength of 400 nm or less; and decomposing by cutting a bond between carbon and oxygen to thereby form an oxide thin-film.
