ABSTRACT:
A variable TCE composition for making dielectric layers having low dielectric constant and low dielectric loss, the composition comprising an admixture of finely divided solids comprising amorphous crystallizable glass, amorphous borosilicate frit, ceramic expansion control additive, and crystallization control additive. The dielectric layers are useful in circuits especially for high density and high frequency applications.
