Method for manufacturing multilayer ceramic substrate and composite sheet

Abstract

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.
