PROBLEM TO BE SOLVED: To provide a method for regenerating an aluminum nitride substrate, and a circuit board using the regenerated aluminum nitride substrate.;SOLUTION: The regeneration method is characterized by heating at a temperature of 1,700-1,780°C, the aluminum nitride substrate in which a brazing filler metal including Mg exists on the surface of an aluminum nitride sintered compact containing no MgO in a sintering aid to eliminate the brazing filler metal. The circuit board is characterized by using the aluminum nitride substrate regenerated by the above method.;COPYRIGHT: (C)2007,JPO&INPIT
