Latest Patents

One of his latest patents is titled "Implanted counted dopant ions." This invention focuses on semiconductor devices that comprise a counted number of dopant atoms implanted in regions of a substrate that are substantially intrinsic semiconductor. The invention involves metallizing one or more doped surface regions of the substrate to form electrodes, where a counted number of dopant ions are implanted in a region of the semiconductor.

Another notable patent is "Method and system for single ion implantation." This invention addresses a method and system for single ion doping and machining by detecting the impact, penetration, and stopping of single ions in a substrate. This detection is crucial for the successful implantation of a counted number of ions into a semiconductor substrate, particularly for constructing a Kane quantum computer. The invention utilizes a potential across two electrodes on the surface of the substrate to create a field that separates and sweeps out electron-hole pairs formed within the substrate. A detector is employed to detect transient current in the electrodes, thereby determining the arrival of a single ion in the substrate.
