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.

Abstract: Dome switches can provide inconsistent positive tactile feedback, particularly when depressed around the edges of a corresponding push button as compared to depression at the middle of the push button. Various arrangements intended to render push buttons that incorporate one or more dome switches more consistent in providing positive tactile feedback, while maintaining a reasonable ease and cost of manufacturing, are discussed herein. A push button with consistent edge performance using a single dome switch incorporates a hinge arm that spans button posts. This reduces or eliminates rotation deflection of a button cap caused by the torsional forces on the push button created by depression forces applied by the user at an edge of the push button. As a result, the dome switch provides a predictable and consistent positive tactile feedback to the user similar to that achieved by a centrally applied depression force.
