Claim Text:
1. A circuit assembly comprising: a substrate including a top surface and a bottom surface, said substrate further including a plurality of microchannels formed through the bottom surface and into the substrate; a diamond layer provided within each of the microchannels in the substrate; a plurality of semiconductor devices provided on the top surface of the substrate where each semiconductor device is positioned directly opposite to a microchannel; and a manifold coupled to the bottom surface of the substrate and including a plurality of channels formed therein that include an impingement jet channel positioned adjacent each microchannel, a return channel positioned adjacent to each microchannel, a supply channel supplying a cooling fluid to the impingement jet channels and a return channel collecting heated cooling fluid from the supply channels so that an impingement jet of the cooling fluid is directed on to the diamond layer for removing heat generated by the semiconductor devices.
