A semiconductor device package that incorporates a combination of ceramic, organic, and metallic materials that are coupled using silver is provided. The silver is applied in the form of fine particles under pressure and a low temperature. After application, the silver forms a solid that has a typical melting point of silver, and therefore the finished package can withstand temperatures significantly higher than the manufacturing temperature. Further, since the silver is an interfacial material between the various combined materials, the effect of differing material properties between ceramic, organic, and metallic components, such as coefficient of thermal expansion, is reduced due to low temperature of bonding and the ductility of the silver.
