  • Patent number: 11921431
    Abstract: A method and a system for inspecting an extreme ultra violet mask and a mask pod for such masks is provided. An EUV mask inspection tool inspects a mask retrieved from a mask pod placed on the load port positioned exterior of the mask inspection tool. The inspection process is performed during a selected period of time. After the inspection process is initiated, a robotic handling mechanism such as a robotic arm or an AMHS picks up the mask pod and inspects the mask pod for foreign particles. A mask pod inspection tool determines whether the mask pod needs cleaning or replacing based on a selected swap criteria. The mask pod is retrieved from the mask pod inspection tool and placed on the load port before the selected period of time lapses. This method and system promotes a reduction in the overall time required for inspecting the mask and the mask pod.

  • Publication number: 20210340693
    Abstract: A method of preparing fiber includes blending bio-compatible ceramic powder and first polyester to form a ceramic powder composition, wherein the bio-compatible ceramic powder and the first polyester have a weight ratio of 10:90 to 60:40. The method further includes blending the ceramic powder composition and second polyester to form a composite material, wherein the ceramic powder composition and the second polyester have a weight ratio of 0.4:99.6 to 40:60. The method also spins the composite material to form a fiber. The first polyester has an intrinsic viscosity (IV) of 0.35 dL/g to 0.55 dL/g, and the second polyester has an intrinsic viscosity (IV) of 0.6 dL/g to 0.8 g/dL. The fiber can be woven to form an artificial ligament/tendon.
