METHOD FOR PRODUCING CERAMIC-ALUMINUM BONDED BODY, METHOD FOR PRODUCING POWER MODULE SUBSTRATE, CERAMIC-ALUMINUM BONDED BODY, AND POWER MODULE SUBSTRATE

摘要

The present invention is a method for producing a ceramic-aluminum bonded body which is obtained by bonding a ceramic member and an aluminum member, the aluminum member prior to bonding being constructed from aluminum with a purity of 99.0 mass% to 99.9 mass%. The method for producing the ceramic-aluminum bonded body includes a heat treating step of heat treating the aluminum member in a range of 400°C or higher and less than the solidus temperature, and a bonding step of bonding the aluminum member that has been subjected to the heat treating step and a ceramic member via a brazing material including Si.
