  • Publication number: 20250048693
    Abstract: A method of manufacturing a semiconductor device includes forming first and second active regions; forming first to fifth gate electrodes, the second gate electrode being between the first and third gate electrodes, the fourth gate electrode being between the third and fifth gate electrodes; and selectively replacing at least one portion of at least one of the gate electrodes with an isolation dummy gate, including: replacing the first and fifth gate electrodes with first and second isolation dummy gates formed in trenches through the first and second active regions; and replacing a first portion of the third gate electrode overlying the second active region with a third isolation dummy gate formed in a first trench through the second active region, resulting in a second portion of the third gate over the first active region, and the third isolation dummy gate aligned with the second portion of the third gate.

  • Patent number: 12212531
    Abstract: Example cross-link interference (CLI) measurement configuration methods and apparatus are described. In one example method, a first network device receives, from a second network device, a first message that indicates information about a CLI measurement. The first network device configures the CLI measurement for a terminal device based on the first message.

  • Patent number: 10288549
    Abstract: Systems and methods for detecting a layer-to-layer transition of a lifting steel wire rope on a reel are described. The system includes a reel assembly for winding a steel wire rope on a reel and a tensioning assembly for tensioning a segment of said steel wire rope. The system further includes a loading assembly and a lead screw sliding assembly. The loading assembly provides a vertical loading to the tensioning assembly so as to generate a loading force between the tensioned steel wire rope and the steel wire rope wound around the reel. The lead screw sliding assembly drives the tensioning assembly so as to move on a horizontal guide rail to generate a relative displacement between the tensioned steel wire rope and the steel wire rope wound around the reel. The tensioning assembly is connected to the loading assembly via a first threaded rod and a static torque sensor.
