Ultra-Thin Silicon and Gallium Arsenide

Valley Design Corporation has developed a process and is supplying on a regular basis, ultra-thin Silicon and GaAs (with circuitry) precision lapped or (CMP), chemically-mechanically polished.

Substrates as thin as 10 microns thick with circuitry were completed. A recent order called for 5" diameter wafers of 3 mil thickness (polished on both sides). Valley Design offers a complete line of lapped, polished and diced substrates, Sapphire, Glass, flat optical pieces and other electro-optical materials.

Note: Approximate optical scratch/dig and Ra relationship for surface finishes.
