  • Patent number: 10483086
    Abstract: An ion implantation system and method are provided where an ion beam is tuned to a first process recipe. The ion beam is scanned along a scan plane at a first frequency, defining a first scanned ion beam. A beam profiling apparatus is translated through the first scanned ion beam and one or more properties of the first scanned ion beam are measured across a width of the first scanned ion, thus defining a first beam profile associated with the first scanned ion beam. The ion beam is then scanned at a second frequency, thus defining a second scanned ion beam, wherein the second frequency is less than the first frequency. A second beam profile associated with the second scanned ion beam is determined based, at least in part, on the first beam profile. Ions are subsequently implanted into a workpiece via the second scanned ion beam.

  • Patent number: 9711329
    Abstract: A method for improving the productivity of a hybrid scan implanter by determining an optimum scan width is provided. A method of tuning a scanned ion beam is provided, where a desired beam current is determined to implant a workpiece with desired properties. The scanned beam is tuned utilizing a setup Faraday cup. A scan width is adjusted to obtain an optimal scan width using setup Faraday time signals. Optics are tuned for a desired flux value corresponding to a desired dosage. Uniformity of a flux distribution is controlled when the desired flux value is obtained. An angular distribution of the ion beam is further measured.
