ABSTRACT:
A composite substrate comprises a metal substrate, an electrically insulating ceramic layer formed on the metal substrate, a metal layer formed on the ceramic layer, a first mixed layer formed in an area near the interface between the metal substrate and the ceramic layer, and a second mixed layer formed in an area near the interface between the ceramic layer and the metal layer, each of the mixed layers being composed of the materials of the layers situated on both sides thereof. The composite substrate may comprise a plurality of electrically insulating dissimilar ceramic layers between the metal substrate and the metal layer, and a mixed layer formed in an area near the interface between any two of the adjacent ceramic layers.
