  • Publication number: 20240313090
    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: 9891405
    Abstract: A camera module of an electronic device includes a lens unit with a first coil, a vibration unit with a second coil, and a magnetic unit. The vibration unit is positioned outside the lens unit and spaces a first certain distance with the lens unit. The magnetic unit is positioned outside the vibration unit and spaces a second distance with the vibration unit. When the first coil receives electrical signal, the first coil is actuated to move with the lens unit. When the second coil receives electrical signal, the second coil is actuated to move with the vibration unit with the vibration unit. Therefore, the magnetic blocks are cooperated with the lens assembly and the vibration block, to make an automatic focusing function and a vibration function being combined in the camera module.

  • Patent number: 9049776
    Abstract: A latching module for latching two housings together includes a rotary member, a compression spring, an elastic sheet, and a magnetic member. The rotary member is attached to one housing, and includes a first surface, a second surface opposite to the first surface, and a peripheral surface. The first surface defines a first receiving hole and a curved groove. The second surface defines a second receiving hole communicating with the first receiving hole. A latching projection extends from the peripheral surface. The compression spring is received in the second receiving hole. The elastic sheet is attached to the peripheral surface. The magnetic member is received in the curved groove. The magnetic member is attracted by another magnet to rotate the latching projection into a latch in another housing.
