Latest Patents

One of his latest patents is titled "Ion implanter having two-stage deceleration beamline." This invention includes an ion source for generating an ion beam, an analyzer for separating unwanted components from the ion beam, and a first beam transport device for transporting the ion beam through the analyzer at a first transport energy. The design features a first deceleration stage positioned downstream of the analyzer, which decelerates the ion beam from the first transport energy to a second transport energy. Additionally, it includes a beam filter for separating neutral particles from the ion beam and a second beam transport device for transporting the ion beam through the beam filter at the second transport energy. The second deceleration stage further decelerates the ion beam to a final energy, delivering it to a target site for ion implantation. In a double deceleration mode, the second transport energy is greater than the final energy for the highest current at low energy. In an enhanced drift mode, the second transport energy equals the final energy for the highest beam purity at low energy.

Another significant patent is the "Apparatus for magnetically scanning and/or switching a charged-particle beam." This apparatus is designed for one-dimensional magnetic scanning or switching of a charged particle beam and can be extended to two dimensions, albeit with added complexity.
