摘要:
A ceramic substrate is provided as one having a large coefficient of thermal expansion α, having properties suitable for use as a high-frequency substrate, being capable of being fired at a low temperature, and having an excellent substrate strength. The ceramic substrate has a main composition containing Mg2SiO4 and a low-temperature-fired component, has the coefficient of thermal expansion a of not less than 9.0 ppm/° C., and contains up to 25 vol. % (excluding zero) ZnAl2O4 or up to 7 vol. % (excluding zero) Al2O3. A dielectric-porcelain composition is provided as one being capable of being fired at a temperature lower than a melting point of an Ag-based metal and being capable of demonstrating a sufficient bending strength even through firing at a low firing temperature. The dielectric-porcelain composition contains Mg2SiO4 as a major component and contains a zinc oxide, a boron oxide, an alkaline earth metal oxide, a copper compound, and a lithium compound as minor components.

摘要:
A highly reliable ceramics substrate which can sufficiently secure a bonding strength of a surface conductor in an initial state and after a lapse of time (e.g., after a PCT) is provided. The multilayer ceramics substrate has a surface conductor on at least one surface of a multilayer body constituted by a plurality of laminated ceramics substrate layers. A reaction phase formed by a reaction between a ceramics component in the ceramics substrate layers and a glass component in the surface conductor is deposited at an interface between the surface conductor and ceramics substrate layers. For example, an alumina filler in the ceramics substrate layers and Zn in the surface conductor react with each other, thereby forming ZnAl2O4 as the reaction phase.
