CLADDING MATERIAL AND ITS FABRICATION METHOD, METHOD FOR MOLDING CLADDING MATERIAL, AND HEAT SINK USING CLADDING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method and a forming method of a cladding material having high thermal conductivity and a small thermal expansion coefficient, and to provide a radiation substrate having high thermal conductivity and the small thermal expansion coefficient using the same.;SOLUTION: The cladding material is constituted by alternately laminating layers 10 formed of a first material, and layers 20 formed of a second material. The thermal expansion coefficient in the second material is smaller than that in the first material. Thermal conductivity in the second material is lower than that in the first material. A total of five or more layers of the layers 10 formed of the first material and the layers 20 formed of the second material are laminated.;COPYRIGHT: (C)2007,JPO&INPIT
