  • Publication number: 20240087851
    Abstract: The present disclosure is directed to an in situ closed-loop radio frequency (RF) power management on RF processes such as a plasma etch process, a plasma chemical vapor deposition process, a plasma physical vapor deposition process, a plasma clean process, or the like. An RF power measurement device according to one or more embodiments of the present disclosure assists the in situ closed-loop RF power management on RF processes. In some embodiments, the RF power measurement device includes a coil-shaped current sensor that is wound around the path between an RF generator and a chamber. The coil-shaped current sensor senses the current flowing through this path so that the power of the RF generator may be calibrated without having to separate the RF generator for separate analysis and calibration. The RF power measurement device allows management of RF power in an in situ closed-loop manner.
