  • Publication number: 20230280664
    Abstract: A reticle carrier described herein is configured to quickly discharge the residual charge on a reticle so as to reduce, minimize, and/or prevent particles in the reticle carrier from being attracted to and/or transferred to the reticle. In particular, the reticle carrier may be configured to provide reduced capacitance between an inner baseplate of the reticle carrier and the reticle. The reduction in capacitance may reduce the resistance-capacitance (RC) time constant for discharging the residual charge on the reticle, which may increase the discharge speed for discharging the residual charge through support pins of the reticle carrier. The increase in discharge speed may reduce the likelihood that an electrostatic force in the reticle carrier may attract particles in the reticle carrier to the reticle.

  • Patent number: 11728675
    Abstract: A power supply apparatus is coupled to an AC power source, a critical load, and a general load. The power supply apparatus includes a UPS, a generator system, a power conversion system, and a controller. The power conversion system includes a first power conversion path and a second power conversion path. The first power conversion path is connected to the critical load and an output side, and the second power conversion path is connected to the general load and an input side. The first power conversion path and the second power conversion path are jointly connected to a DC bus. When the controller determines that the AC power source is abnormal, the controller controls disconnecting the AC power source, and activates the UPS to supply power to the critical load so as to enable the first power conversion path and disable the second power conversion path.

  • Patent number: 11698591
    Abstract: An EUV photolithography system utilizes a baseplate of an EUV pod to unload an EUV reticle from a chuck within an EUV scanner. The baseplate includes a top surface and support pins extending from the top surface. The when the reticle is unloaded onto the baseplate, the support pins hold the reticle at relatively large distance from the top surface of the baseplate. The support pins have a relatively low resistance. The large distance and low resistance help ensure that particles do not travel from the baseplate to the reticle during unloading.

  • Publication number: 20230064313
    Abstract: A system and method for management of heterogeneous bare metal servers is disclosed. The system includes target bare metal servers coupled to a network and an administrative server. The administrative server executes a framework for managing the bare metal servers. The framework includes unified APIs for performance of management functions. A recognition engine receives identification information from the server and selects a driver from a driver library based on the identification information. Each of the drivers in the driver library is associated with a different type of bare metal server. A driver loader loads the selected driver to translate the unified APIs to native APIs on the bare metal server to perform the management function on the server.
