  • Publication number: 20240055217
    Abstract: A method of monitoring compliance with filter specification during the implantation of ions into a substrate reading a signature of the filter and comparing the read signature with filter signatures stored in a database to identify properties of the filter including at least one of a maximum allowable temperature of the filter and a maximum allowable accumulated ion dose of the filter. The temperature and/or the accumulated ion dose of the filter is measured while ions are implanted into the substrate by an ion beam passing through the filter. The implantation is terminated when the measured temperature or accumulated ion dose of the filter reaches or exceeds the maximum allowable threshold.
