摘要：
A ceramic substrate is used for an electric or electronic circuit, and comprises a ceramic foundation and at least one conductive island formed of aluminum or an aluminum alloy and bonded to one surface of the ceramic foundation for providing conductive paths to circuit components connected thereto, wherein the aluminum or aluminum-alloy island is brazed to the ceramic foundation with a brazing alloy selected from the group consisting of aluminum-silicon alloy, aluminum-germanium alloy, aluminum-silicon-magnesium alloy and aluminum-silicon-germanium alloy so that thermal stress between the ceramic foundation and the conductive island is taken up.
