ABSTRACT:
A circuit board is provided having an electrically conductive substrate. Preferably, the electrically conductive substrate comprises molybdenum and copper. The substrate is selectively coated with a dielectric material which is capable of withstanding volatilization at high temperatures. The coefficient of thermal expansion of the substrate is substantially equal to that of the circuitry components which are placed thereon. A method of providing such a support structure is also disclosed.
