A method of making a microwave semiconductor component and concurrently forming therewith a mounting membrane adapted for positioning the semiconductor component in an RF transmission medium such as a waveguide. Substantially concurrently with the deposition of a metallic film in connection with forming a semiconductor elements, there is deposited a metallic membrane on the base silicon substrate and outside of the circuit element. The outer periphery of the base substrate is removed to expose the membrane. The metallic membrane is preferably of gold.
