    摘要: PROBLEM TO BE SOLVED: To provde a method for manufacturing a nitride ceramics circuit board having a satisfactory insulation and excellent in productivity. SOLUTION: The method for manufacturing the nitride ceramics circuit board comprises the steps of forming a scribble line to the nitride ceramics board by laser to divide the substrate, bonding it with a metal plate by an active metal soldering method after forming the scribble line by a discontinuous laser hole, and forming the circuit by an etching method. After forming the circuit by the etching, the solder material remaining at a part with the metal plate removed, its alloy layer, nitride layer or the like are removed. COPYRIGHT: (C)2008,JPO&INPIT
