CERAMIC SUBSTRATE, SUBSTRATE FOR POWER MODULE, AND MANUFACTURING METHOD OF SUBSTRATE FOR POWER MODULE

摘要

PROBLEM TO BE SOLVED: To provide a ceramic substrate of a substrate for a power module, a substrate for a power module having this ceramic substrate, and a manufacturing method of the substrate for the power module capable of uniformly bonding a ceramic substrate formed of an aluminum nitride and a metal layer in a short time.

SOLUTION: A infrared absorption layer 22 having a higher infrared absorptivity than an infrared transparency aluminum nitride layer 21 is laminated between a plurality of infrared transparency aluminum nitride layers 21 to form a ceramic substrate 2.
