  • Publication number: 20250107170
    Abstract: Methods for isolating two adjacent transistors are disclosed. A substrate has a first semiconducting fin on a first region and a second semiconducting fin on a second region, and the first semiconducting fin and the second semiconducting fin contact each other at a jog region. A dummy gate within or adjacent the jog region is removed to expose a portion of the first semiconducting fin and form an isolation volume. Etching is performed to remove the exposed portion of the first semiconducting fin and create a trench in the substrate. The trench and the isolation volume are filled with at least one dielectric material to form an electrically isolating structure between the first region and the second region. Additional dummy gates in each region can be removed and replaced with an electrically conductive material to form two adjacent transistors electrically isolated from each other.

  • Patent number: 12262303
    Abstract: A UE activates a timer for applying access control to transmissions associated with a certain access category during an access control period, in response to a first system information message received via a radio interface and a mobile-originated access request (1702). While the timer is running, the UE receives a second message that indicates a potential transition of the UE (i) from a current state associated with a protocol for controlling radio resources to another state associated with the protocol, or (ii) from a current cell to a new cell (1704). In response to the second message, the UE continues to apply the access control to the transmissions for the access category, for a remainder of the access control period (1706).
