Abstract
A power electronics device comprises a power electronics carrier includes a non-corrosive metal substrate and a region of electrical isolation material that forms a direct interface with the metal substrate, and a first semiconductor die mounted on the region of electrical isolation material, and a coefficient of thermal expansion of the region of electrical isolation material substantially matches a coefficient of thermal expansion of metal from the metal substrate at the direct interface.
