Method of manufacturing a substrate coated with multiple thick films

摘要

A method of manufacturing a substrate coated with a plurality of thick films wherein conductive layers are wholly prepared from conductive paste, and also a device comprising the substrate. The present invention offers the advantages that the drawbacks accompanying the conventional conductor of silver-palladium base are overcome by forming a resistor having a required resistivity and a high reproducibility. A conductive paste and insulative paste are fired at a lower temperature than that at which the resistor paste is fired, without reducing the adhesion strength of the conductive layer to the substrate. A low temperature melting point crystalline composition is used as an insulative layer to ensure that the resistance of the resistor is not adversely affected by repeated firings.
