  • Publication number: 20240363318
    Abstract: A fabrication system for fabricating IC is provided. A processing tool includes a RF sensor. The RF sensor wirelessly detects intensity of a RF signal. A computation device extracts statistical characteristics with a sampling rate. When the detected intensity of the RF signal exceeds a threshold value or a threshold range, a fault detection and classification (FDC) system notifies the processing tool to adjust the RF signal or stop tool to check parts damage.

  • Patent number: 12057301
    Abstract: A fabrication system for fabricating IC is provided. A processing tool includes at least one electrode and a RF sensor. The electrode is configured to receive a radio frequency (RF) signal from an RF signal generator during first and second semiconductor manufacturing processes. The RF sensor wirelessly detects intensity of the RF signal. A computation device extracts statistical characteristics with a sampling rate based on the detected intensity of the RF signal. A fault detection and classification (FDC) system includes a processor. The processor is configured to determine whether or not the detected intensity of the RF signal exceeds a threshold value or a threshold range according to the extracted statistical characteristics. When the detected intensity of the RF signal exceeds the threshold value or the threshold range, the processor notifies the processing tool to adjust the RF signal or stop tool to check parts damage.
