Gold-coated silicon wafers, and gold-coated silicon chips are used extensively as substrates for analytical characterization of materials.  For example, materials deposited onto gold-coated wafers can be analized via ellipsometry, Raman spectroscopy or infrared (IR) spectroscopy due to the high-reflectivity and favorable optical properties of gold.  In addition, gold-coated silicon wafers are excellent substrates for fabricating electrodes, electrochemical sensors, self-assembled monolayers, photonic devices, and other advanced technologies.
