SUBSTRATE FOR POWER MODULES, SUBSTRATE WITH HEAT SINK FOR POWER MODULES AND POWER MODULE WITH HEAT SINK
A power-module substrate including a circuit layer having a first aluminum layer bonded on one surface of a ceramic substrate and a first copper layer bonded on the first aluminum layer by solid-phase-diffusion bonding, and a metal layer having a second aluminum layer made from a same material as the first aluminum layer and bonded on the other surface of the ceramic substrate and a second copper layer made from a same material as the first copper layer and bonded on the second aluminum layer by solid-phase-diffusion bonding, in which a thickness t1 of the first copper layer is 1.7 mm or larger and 5 mm or smaller, a sum of the thickness t1 of the first copper layer and a thickness t2 of the second copper layer is 7 mm or smaller, and a ratio t2/t1 between the thickness t1 of the first copper layer and the thickness t2 of the second copper layer is larger than 0 and 1.2 or smaller except for a range of 0.6 or larger and 0.8 or smaller.
