Latest Patents
One of his latest patents is the "Ion beam blanking apparatus and method." This invention provides beam blanking by utilizing an aperture through which the beam passes during unblanked periods. It includes elements for deflecting the beam during blanking, ensuring that the beam is deflected away from the aperture. The apparatus generates a potential that exceeds the kinetic energy of charged particles emitted from the aperture, thereby enhancing beam stability and reducing issues such as hydrocarbon cracking and charge accumulation.
Another significant patent is the "Localized vacuum apparatus and method." This invention generates a localized, non-contact vacuum seal at a selected process region of a workpiece surface. The apparatus features a vacuum body with concentric grooves and a central bore for transmitting a process energy beam. The method involves placing the vacuum body in proximity to the workpiece surface and differentially evacuating the grooves to create vacuum chambers that minimize atmospheric particle influx.
