ABSTRACT:
A ceramic substrate is used for an electric or electronic circuit comprises a ceramic plate formed of a substance mainly composed of aluminum nitride, and conductive islands formed of aluminum or an aluminum alloy and bonded to one surface of the ceramic plate for providing conductive paths to circuit components connected thereto, wherein the aluminum islands decrease the total weight of the ceramic substrate and enhance a resistance against repetition of a thermal stress.
