Ceramic Substrate Wikipedia

Direct bonded copper dbc substrates are commonly used in power modules because of their very good thermal conductivity they are composed of a ceramic tile commonly alumina with a sheet of copper bonded to one or both sides by a high temperature oxidation process the copper and substrate are heated to a carefully controlled temperature in an atmosphere of nitrogen containing about 30 ppm.
