Mutlilayer glass ceramic substrate and method of fabricating the same

摘要

A multilayer glass ceramic substrate includes a glass ceramic layer and a plurality of conductive layers laminated via the glass ceramic layer. The glass ceramic layer is composed of inorganic compound consisting of aluminum oxide, borosilicate glass, anorthite crystal and celsian crystal wherein the aluminum oxide is contained in the range of 12 to 59.6 weight percent, the borosilicate glass is contained in the range of 18 to 69.6 weight percent, the anorthite crystal is contained in the range of 1 to 40 weight percent and the celsian crystal is contained in the range of 1 to 5 weight percent so that the total is 100 weight percent.
