ABSTRACT:
Low dielectric constant dielectric ceramics for a borosilicate-based low temperature fired multi-layer substrate is disclosed which can be fired at a wide temperature range of above and below 900° C. and exhibits a low loss electrical property. By controlling the types and addition amount of the alkaline earth metal oxide, the linear shrinkage behavior can be considerably controlled while maintaining the electrical property unchanged. The composition facilitates matching a linear shrinkage with a heterogeneous material having certain shrinkage characteristics.
