Latest Patents

Dwight Roh holds a patent for a "Blended energy implant." This invention involves ion implantation systems and methods that implant varying energies of an ion beam across a workpiece in a serial single-workpiece end station. The system utilizes electrodes of an acceleration/deceleration stage, bend electrode, and/or energy filter to control the final energy or path of the ion beam directed at the workpiece. The design includes a scanning apparatus that scans the ion beam and/or the workpiece, while a power source provides varied electrical bias signals to the electrodes. A controller selectively varies these electrical bias signals in conjunction with the scanning process, based on the desired ion beam energy at the workpiece. Additionally, a waveform generator can provide the necessary variation and synchronize the electrical bias signals supplied to the acceleration/deceleration stage, bend electrode, and/or energy filter.
