Latest Patents

One of his latest patents is the "Lamella creation method and device using fixed-angle beam and rotating sample stage." This innovative system is designed to create a substantially planar face in a substrate. It involves directing one or more beams at a first surface of a substrate to remove material from a specific location, with the beam offset from a normal to the first surface by a curtaining angle. The system sweeps the beams in a plane that is perpendicular to the first surface to mill initial cuts, exposing a second surface that is substantially perpendicular to the first surface. The substrate is then rotated about an axis that is not normal to the first beam or parallel to it. The first beam is directed at the second surface to remove additional material without changing the curtaining angle, and the beams are scanned across the second surface to mill finishing cuts.

Another significant patent is for "High voltage isolation of an inductively coupled plasma ion source with a liquid that is not actively pumped." This inductively-coupled plasma source is designed for a focused charged particle beam system. It includes a plasma chamber surrounded by a fluid that provides high voltage isolation between the plasma chamber and nearby parts at ground potential. The design incorporates cooling devices that utilize evaporative cooling and heat pipes to dissipate heat from the plasma chamber into the surrounding environment.
