<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing method for a substrate for a power module, that can efficiently produce a substrate for a power module with high strength of an interface between a ceramic substrate and an aluminum layer composed of aluminum or an aluminum alloy and with excellent reliability, and provide the substrate for the power module. <P>SOLUTION: The manufacturing method for a substrate for a power module includes: a fixture step of fixing Ag to a region where at least an aluminum layer 12 is formed on one surface of a ceramic substrate 11 and forming a fixture layer 24 including Ag; a molten aluminum filling step of disposing the ceramic substrate 11 on which the fixture layer 24 is formed in a mold 50, filling the mold 50 with molten aluminum M, and bringing the ceramic substrate 11 and the molten aluminum M into contact with each other; and a solidification step of solidifying the molten aluminum M in a state of being in contact with the ceramic substrate 11. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
