A power electronics device, comprising:
- a power electronics carrier comprising 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
- wherein 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.
A power electronics carrier, comprising:
- a non-corrosive metal substrate;
- and
- a region of electrical isolation material that forms a direct interface with the metal substrate, and
- wherein a coefficient of thermal expansion of the region of electrical isolation material substantially matches a coefficient of thermal expansion of the metal at the direct interface.
A method of producing a power electronics carrier, the method comprising:
- providing a metal substrate;
- and
- forming a region of electrical isolation material on the metal substrate such that the region of electrical isolation material directly interfaces with the metal substrate, and
- wherein 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.
