A method is provided for easily producing thick multi-layer substrates maintaining highly accurate resistances with little variation. A thick-film resistor 6 on a ceramic substrate 1 is fired at a temperature higher than the temperature of firing a glass insulating layer 2 that is formed thereon in contact...http://www.google.fr/patents/US5593722?utm_source=gb-gplus-shareBrevet US5593722 - Method of producing thick multi-layer substrates
