  • Patent number: 9271389
    Abstract: A device mounting board includes a metallic substrate, an oxide film formed such that the surfaces of the metallic form are oxidized, an insulating resin layer disposed on the oxide film facing one main surface of the metallic layer, and a wiring layer disposed on the insulating resin layer. The film thickness of a certain partial region of the oxide film disposed below a first semiconductor device is greater than that of the other regions surrounding the partial region of the oxide film. Conversely, the film thickness of the insulating resin layer underneath a second semiconductor device is less than that of the insulating resin layer underneath the first semiconductor device.
    Type: Grant
