  • Patent number: 11996468
    Abstract: A method of fabricating a device includes providing a fin having an epitaxial layer stack with a plurality of semiconductor channel layers interposed by a plurality of dummy layers. In some embodiments, the method further includes exposing lateral surfaces of the plurality of semiconductor channel layers and the plurality of dummy layers within a source/drain region of the semiconductor device. In some examples, the method further includes etching the exposed lateral surfaces of the plurality of dummy layers to form recesses and forming an inner spacer within each of the recesses, where the inner spacer includes a sidewall profile having a convex shape. In some cases, and after forming the inner spacer, the method further includes performing a sheet trim process to tune the sidewall profile of the inner spacer such that the convex shape of the sidewall profile becomes a substantially vertical sidewall surface after the sheet trim process.

  • Patent number: 8973911
    Abstract: A movable jaw quick release apparatus of a vice comprises a tooth base, a movable jaw and two restriction elements. The tooth base is formed with two inclined guide grooves, each of which has a first inclined surface, a second inclined surface and a bottom surface. The left and the right side surfaces of the movable jaw are formed with a through hole respectively. Each restriction element penetrates one of the through holes and moves between a first position and a second position along one of the inclined guide groove As the movable jaw generates vibration forces, each restriction element transfers the vibration forces to the tooth base, therefore, the movable jaw do not move upwardly and shake toward a work piece and reduce its clamping force for the work piece.
