Blended energy ion implantation
20230038392 · 2023-02-09 ·

Ion implantation systems and methods implant varying energies of an ion beam across a workpiece in a serial single-workpiece end station, where electrodes of an acceleration/deceleration stage, bend electrode and/or energy filter control a final energy or path of the ion beam to the workpiece. The bend electrode or an energy filter can form part of the acceleration/deceleration stage or can be positioned downstream. A scanning apparatus scans the ion beam and/or the workpiece, and a power source provides varied electrical bias signals to the electrodes. A controller selectively varies the electrical bias signals concurrent with the scanning of the ion beam and/or workpiece through the ion beam based on a desired ion beam energy at the workpiece. A waveform generator can provide the variation and synchronize the electrical bias signals supplied to the acceleration/deceleration stage, bend electrode and/or energy filter.
