  • Publication number: 20150371725
    Abstract: An inorganic material paste obtained by mixing an organometallic compound, inorganic material particles, and a solvent. Additionally provided is an inorganic material paste obtained by mixing inorganic material particles, which are obtained by subjecting an organometallic compound to calcination or light irradiation, and a solvent. The foregoing inorganic material paste can reduce the amount of glass material, reduce the film thickness because the volume density of the functional material is high, yield favorable production efficiency, and achieve cost reduction since it is suitable for mass production. For instance, upon producing a thin film resistor, the resistor obtained by using the paste of the present invention is characterized in having superior stability even in the form of a thin film, and having minimal change in the resistance value caused by self-heating even under a high current.
