  • IN-SITU FINGERPRINTING FOR ELECTROCHEMICAL DEPOSITION AND/OR ELECTROCHEMICAL ETCHING
    Publication number: 20240044039
    Abstract: Electrochemical analysis method and system for monitoring and controlling the quality of electrochemical deposition and/or plating processes. The method uses a fingerprinting analysis method of an output signal to indicate whether the chemistry and/or process is operating in the normally expected range and utilizes one or more substrates as working electrode(s) and a) whereby the potential between the one or more working electrodes and one or more reference electrodes is analyzed to provide an output signal fingerprint which is represented as potential difference as a function of time or b) the input power of a process power supply to provide input energy in the form of current and/or potential between the working electrode(s) and a counter-electrode whereby the method utilizes the potential between the one or more working electrode(s) and at least one of: one or more reference electrodes; or one or more counter-electrodes; to provide an output signal fingerprint.

  • In-situ fingerprinting for electrochemical deposition and/or electrochemical etching
    Patent number: 10876219
    Abstract: The invention relates to an electrochemical analysis method for monitoring and controlling the quality of electrochemical deposition and/or plating processes whereby the electrochemical analysis method uses a fingerprinting analysis method of an output signal to have an indicator of whether the chemistry and/or process is operating in the normally expected range, whereby the method utilizes one or more substrates as working electrode(s) and a) whereby the potential between the one or more working electrodes and one or more reference electrodes being analyzed to provide an output signal fingerprint which is represented as potential difference as a function of time or b) the input power of a process power supply to provide input energy in the form of current and/or potential between the working electrode(s) and a counter-electrode whereby the method utilizes the potential between the one or more working electrode(s) and at least one of: one or more reference electrodes; or one or more counter-electrodes; to pro
