  • Patent number: 11973117
    Abstract: Methods of forming contacts for source/drain regions and a contact plug for a gate stack of a finFET device are disclosed herein. Methods include etching a contact opening through a dielectric layer to expose surfaces of a first source/drain contact and repairing silicon oxide structures along sidewall surfaces of the contact opening and along planar surfaces of the dielectric layer to prevent selective loss defects from occurring during a subsequent selective deposition of conductive fill materials and during subsequent etching of other contact openings. The methods further include performing a selective bottom-up deposition of conductive fill material to form a second source/drain contact. According to some of the methods, once the second source/drain contact has been formed, the contact plug may be formed over the gate stack.

  • Publication number: 20240080376
    Abstract: A task dispatching method for EPD tag devices includes receiving a task command; the server system forwarding the task command to a target router to which the target EPD tag device is connected; the target router checking whether the target EPD tag device is currently connected thereto; when it is determined that the target EPD tag device is not currently connected to the target router, the target router notifying the server system that the target EPD tag device is offline; in response to receiving an online notification indicating that the target EPD tag device is connected to another router, the server system updating a connection list accordingly, and forwarding the task command to an updated target router; and when it is determined that the target EPD tag device is currently connected to the target router, the target router delivering the task command to the target EPD tag device.

  • Patent number: 11500214
    Abstract: An augmented reality (AR) device includes a main body, a support element, and a lens module. The main body includes a base, a projector, and a first pivot portion. The projector is pivoted to the base by using the first pivot portion, so that the projector is capable of rotating relative to the base by using the first pivot portion as a first rotation axis. The support element is pivoted to a first end portion of the base and is configured to wear on a head of a user. The lens module is pivoted to a second end portion of the base and the second end portion is opposite to the first end portion. The lens module is capable of rotating relative to the base and being overlapped under the base. Through a rotatable and foldable accommodation structure, the augmented reality device is easier to be carried and accommodated.

  • Publication number: 20190307218
    Abstract: The present invention relates to a mobile phone housing, which may be configured to contain a mobile phone. The mobile phone housing includes a plastic body and a leather interlayer. The plastic body includes a mobile phone accommodating portion configured to contain the mobile phone, an outer surface and a retaining wall. The outer surface is disposed on an opposite side of the mobile phone accommodating portion, and the retaining wall is located on the outer surface. The leather interlayer includes a card insertion portion. The leather interlayer is attached to the outer surface, and the retaining wall surrounds the leather interlayer. By means of the structural design of the present invention, the manpower and time required for production can be reduced, and the yield can be increased, thereby reducing the production costs. In addition, the retaining wall can protect an edge of the leather interlayer from being worn easily.

  • Patent number: 8584996
    Abstract: A support stand includes a first casing, a rotary mechanism, a second casing and a holder. The rotary mechanism is disposed in the first casing and has a first gear and a threaded rod coordinated with each other. The second casing is connected with the rotary mechanism. The second casing is able to rotate from a first position to a second position in relative to the first casing. The holder is connected with the threaded rod. When the second casing is at the first position, the holder is stored in the first casing. When the second casing is rotated to the second position, the second casing drives the first gear to coordinately rotate the threaded rod so as to push the holder out of the first casing. The support stand occupies less space as the holder is stored, and it has better overall integrity.
