An infrared sensor manufacturing method according to this invention includes a step of forming a bridge structure of an insulating material on an Si substrate, a step of forming a vanadium oxide thin film on the bridge structure by a dry film forming method, a step of irradiating laser light onto the vanadium oxide thin film to thereby change material properties thereof, a step of forming the vanadium oxide thin film with the changed material properties into a bolometer resistor having a predetermined pattern, and a step of forming a protective layer of an insulating material so as to cover the bolometer resistor having the predetermined pattern and the bridge structure.

Infrared sensor manufacturing method suitable for mass production

A metal complex composition containing complexes having metal species of a rare earth element, barium and copper and ligands of a trifluoroacetic acid or pentafluoropropionic acid ligand, a pyridine ligand and an acetylacetone ligand. A superconductive film may be obtained by applying an organic solvent solution of the above metal complex composition to a substrate and by heat treating the coating.

In an infrared ray sensor for a bolometer, a bridge structure body, a resistive element film for the bolometer, and a protection film is formed via a space on a substrate, and is formed into a solution form by dissolving metal organic compound into solvent. The solution is applied and dried. A laser ray is irradiated for the solution with wavelength of 400 nm or less. A bond between carbon and oxygen is decomposed and cut to thereby form an oxide thin-film.

Method for manufacturing infrared ray sensor

An oxide for use in a bolometer with an oxide thin-film formed is manufactured on an insulating substrate. Metal organic compound is dissolved in solvent to form solution during manufacturing the oxide thin-film. The solution is applied on the insulating substrate, and the applied solution is dried. A bond between carbon and oxygen is cut and decomposed by irradiating a laser ray with wavelength of 400 nm or less. A generated oxide is crystallized.

Method of manufacturing oxide thin film for bolometer

There is disclosed a method for producing a metal oxide, which comprises the steps of: dissolving a metal organic compound (e.g. a metal organic acid salt, a metal acetylacetonato complex, and a metal alkoxide having an organic group with 6 or more carbon atoms) in a solvent to provide a state of solution, applying the solution onto a substrate, drying the solution, and subjecting the resultant substrate to irradiation with a laser light of a 400 nm or less wavelength, to form a metal oxide on the substrate. According to that method, a metal oxide can be produced without applying a heat treatment at a high temperature of the degree adopted in the conventionally known application thermal decomposition method.
