Latest Patents
One of his latest patents is titled "Chemical vapor deposition of metals on a spherical shaped semiconductor substrate." This patent discloses a method and system for chemical vapor deposition (MO CVD) of a metal layer upon a spherical substrate at atmospheric pressure. The method involves using a reactor made of quartz, where the semiconductor spherical substrate is heated by an infrared heater. This heater operates at a wavelength between 1 and 3 microns, allowing for effective absorption by the substrate while being transmitted by the quartz.
Another significant patent is "Method and apparatus for blanket aluminum CVD on spherical integrated." This invention outlines a method and apparatus for metal-organics chemical vapor deposition (MO CVD) of a metal layer on a spherical substrate. The process includes pretreating the substrate with a vapor of a first precursor before exposing it to a thermally dissociated precursor of metal. This ensures a uniformly deposited metal layer coverage over the substrate, which is then annealed and cooled.
