Publication number: 20100059252Abstract: A high-quality resistor pattern and conductor pattern is formed on an external surface of a multilayer ceramic substrate by an ink jet method. A composite sheet including a first ceramic green layer and a shrinkage-retardant layer is formed, and a resistor pattern and a conductor pattern are formed on the first ceramic green layer of the composite sheet by an ink jet method. Subsequently, a plurality of second ceramic green layers are stacked with the composite sheet such that the shrinkage-retardant layer of the composite sheet defines an outermost layer, thus forming a multilayer composite including an unfired multilayer ceramic substrate and the shrinkage-retardant layer. Then, the multilayer composite is fired, and the shrinkage-retardant layer is removed to obtain a sintered multilayer ceramic substrate.Type: ApplicationFiled: November 19, 2009Publication date: March 11, 2010Applicant: MURATA MANUFACTURING CO., LTD.Inventors: Yusuke OTSUKA, Kazuo KISHIDA, Takahiro TAKADA
