Abstract:
Provided is a heat-sink-attached power-module substrate, in which a metal layer and first layers are formed from aluminum sheets having a purity of 99.99 mass % or greater and a heat sink and second layers are formed from aluminum sheets having a purity lower than that of the metal layer and the first layers: when a thickness is t1 (mm), a joined-surface area is A1 (mm2), yield strength at 25° C. is σ11 (N/mm2), yield strength at 200° C. is σ12 (N/mm2) in the second layers; a thickness is t2 (mm), a joined-surface area is A2 (mm2), yield strength at 25° C. is σ21 (N/mm2), and yield strength at 200° C. is σ22 (N/mm2) in the heat sink.

Claim (Index 9):
The heat-sink-attached power-module substrate according to  claim 1 , wherein the second layers are formed from aluminum sheet having larger yield strength at 200\u00b0 C. than that of the heat sink.
