Abstract

A heat-sinked electronic component includes a first layer of synthetic diamond having a relatively low thermal conductivity. A second layer of synthetic diamond is adjacent the first layer, the second layer of synthetic diamond having a relatively high thermal conductivity, the second layer being thinner than the first layer. An electronic component is mounted on the second layer of synthetic diamond. In a disclosed embodiment, the thermal conductivity of the diamond of the second layer is at least fifteen percent higher than the thermal conductivity of the diamond of the first layer, and the first layer is at least twice as thick as second layer.
