  • Patent number: 12167525
    Abstract: An extreme ultra violet (EUV) radiation source apparatus includes a collector, a target droplet generator for generating a tin (Sn) droplet, a rotatable debris collection device and a chamber enclosing at least the collector and the rotatable debris collection device. The rotatable debris collection device includes a first end support, a second end support and a plurality of vanes, ends of which are supported by the first end support and the second end support, respectively. A surface of at least one of the plurality of vanes is coated by a catalytic layer, which reduces a SnH4 to Sn.

  • Publication number: 20240354487
    Abstract: The present disclosure describes an example method for routing a standard cell with multiple pins. The method can include modifying a dimension of a pin of the standard cell, where the pin is spaced at an increased distance from a boundary of the standard cell than an original position of the pin. The method also includes routing an interconnect from the pin to a via placed on a pin track located between the pin and the boundary and inserting a keep out area between the interconnect and a pin from an adjacent standard cell. The method further includes verifying that the keep out area separates the interconnect from the pin from the adjacent standard cell by at least a predetermined distance.

  • Patent number: 12110624
    Abstract: A sewing machine includes a main body and a quick release needle plate module. The main body includes a base seat having an inner frame, and an outer case that is mounted to the inner frame and that defines an accommodating compartment. The quick release needle plate module includes a catch member, and a needle plate that covers the accommodating compartment, that is detachably pivoted to a rear section of the inner frame, and that engages the catch member. The quick release needle plate module further includes a press member inserted through the outer case and the inner frame, and operable to push the catch member to disengage the catch member. The needle plate has a plate body that covers the accommodating compartment, and a resilient member mounted between the inner frame and the plate body for driving pivot action of the plate body away from the inner frame.
