In accordance with one or more embodiments, a semiconductor device comprises a semiconductor die having a heat region disposed on at least one portion of the semiconductor die, and a diamond substrate disposed proximate to the semiconductor die, wherein the diamond substrate is capable of dissipating heat from the diamond substrate via at least one or more bumps coupling the diamond substrate to the heat region of the semiconductor die.

A thin GaAs Substrate can be provided with a copper back-metal layer to allow the GaAs Substrate to be packaged using conventional plastic packaging technologies. By providing the GaAs Substrate with a copper back-metal layer, the GaAs Substrate can be made thinner than 2 mils (about 50 microns), thereby reducing heat dissipation problems and allowing the semiconductor die to be compatible with soft-solder technologies. By enabling the semiconductor die to be packaged in a plastic package substantial cost savings can be achieved.
