Abstract
In summary, a vertical metalized transition in the form of a via goes from the back side of a high thermal conductivity substrate and through any semiconductor layers thereon to a patterned metalized strip, with the substrate having a patterned metalized layer on the back side that is provided with a keep away zone dimensioned to provide impedance matching for RF energy coupled through the substrate to the semiconductor device while at the same time permitting the heat generated by the semiconductor device to flow through the high thermal conductivity substrate, through the back side of the substrate and to a beat sink.
