摘要：Ceramic substrates () for microelectronic modules are formed in multiple layers(& ) fused into a unitary one-piece assembly. The layers contain the same ceramicmaterial but in different purity so that one outer layer () is optimal in composition forbonding to a thick film conductor () and the other outer layer () is optimal in compositionfor bonding to a thin film conductor (). In a dual composition substrate embodiment onelayer is formed of a 96% alumina composition and the second layer is formed of a 99.6%alumina composition.
