  • Publication number: 20240353767
    Abstract: A method of removing a particle from a pellicle includes moving a nozzle over a surface of a membrane of the pellicle to a location of the particle. A droplet of a liquid material is dispensed from the nozzle to cover the particle on the surface of the membrane. A contact of the droplet with the nozzle is monitored and maintained. The droplet carrying the particle is horizontally dragged along the surface of the membrane toward an edge thereof by the nozzle using the surface tension of the droplet. The droplet carrying the particle is sucked off from the edge of the membrane by a vacuum pump, thereby automatically and safely removing the particle without damaging the pellicle.

  • 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.
