Latest Patents
One of Lu's latest patents is titled "Process for the direct production of germanium tetrachloride from hydrated germanate-containing solids using gaseous hydrogen chloride." This invention relates to a system and method for recovering germanium from Modified Chemical Vapor Deposition (MCVD) processing wastes. The method involves the direct reaction of gaseous hydrogen chloride with recovered materials, leading to the rapid and complete chlorination of germanates, which yields germanium tetrachloride. The product is completely volatilized and removed during the exothermic process.
Another significant patent is the "Method for coating heterogeneous substrates with homogeneous layers." This invention is based on the discovery that inhomogeneity in films deposited on heated heterogeneous substrates can be reduced by patterning large area metal structures. Specifically, metal structures larger than 2 mm² are patterned so that the metal is within 1 mm of a metal edge. This technique enhances the homogeneity of subsequently deposited layers, such as silicon nitride, over a large area.
