Thin film sensor

特許 係属中 [Problems] It is an object to provide processes for the production of thin-film sensors whereby crystals are strongly oriented without cost-adding steps such as heating and variations in electrical properties are small among the obtainable products. [Means for Resolution] A process of producing a thin-film sensor is a process of producing a thin-film sensor that include an insulating substrate and an electrical resistor which is made of a metal and is provided on the insulating substrate, the said process including a step of forming the electrical resistor by sputtering the metal while applying a negative direct-current voltage to the insulating substrate.
