  • Patent number: 12294519
    Abstract: A first packet flow and a second packet flow support a first protocol, a third packet flow and a fourth packet flow support a second protocol, and a priority of the first protocol is lower than a priority of the second protocol. The first packet flow and the third packet flow are transmitted from a first ingress port to a first egress port. The second packet flow and the fourth packet flow are transmitted from a second ingress port to a second egress port. When the packet processing device is in a congested state, a bandwidth modulator performs a first suppression process on the first packet flow at the first ingress port, and the bandwidth modulator performs a second suppression process on the second packet flow at the second egress port or on the third packet flow at the first ingress port.

  • Patent number: 12292695
    Abstract: An EUV lithographic apparatus includes a wafer stage and a particle removing assembly for cleaning a wafer for an extreme ultraviolet (EUV) lithographic apparatus. The wafer stage includes a measurement side and an exposure side. The particle removing assembly includes particle removing electrodes, an exhaust device and turbomolecular pumps. The particle removing electrodes is configured to direct debris from the chamber by suppressing turbulence such that the debris can be exhausted from the wafer stage to the outside of the processing apparatus. In some embodiments, turbomolecular pumps are turned off in the measurement side of the wafer stage so that an exhaust flow can be guided to an exposure side of the wafer stage. In some embodiments, the speed of voltage rise to the electrodes of the wafer chuck is adjusted.
