METHOD FOR PRODUCING MULTILAYER CERAMIC SUBSTRATE AND COMPOSITE SHEET

摘要

To form a high-quality resistor pattern and conductor pattern on an external surface of a multilayer ceramic substrate by an ink jet method. A composite sheet (11) including a first ceramic green layer (2a) and a shrinkage-retardant layer (10) is formed, and a resistor pattern (4) and a conductor pattern (5) are formed on the first ceramic green layer (2a) of the composite sheet (11) by an ink jet method. Subsequently, a plurality of second ceramic green layers (3a) are stacked with the composite sheet (11) such that the shrinkage-retardant layer (10) of the composite sheet (11) defines the outermost layer, thus forming a multilayer composite (13) including a unfired multilayer ceramic substrate (1a) and the shrinkage-retardant layer (10). Then, the multilayer composite (13) is fired, and the shrinkage-retardant layer (10) is removed to obtain a sintered multilayer ceramic substrate (1).
