  • Publication number: 20230091153
    Abstract: A method of forming a semiconductor device. A substrate having a fin structure is provided. A dummy gate is formed on the fin structure. A polymer block is formed adjacent to a corner between the dummy gate and the fin structure. The polymer block is subjected to a nitrogen plasma treatment, thereby forming a nitridation layer in proximity to a sidewall of the dummy gate under the polymer block. After subjecting the polymer block to the nitrogen plasma treatment, a seal layer is formed on the sidewall of the dummy gate and on the polymer block. An epitaxial layer is then grown on a source/drain region of the fin structure. The dummy gate is then replaced with a metal gate.

  • Patent number: 11331567
    Abstract: A game controller integrates a trigger at a side of a planar controller housing, the trigger rotating within the plane of the controller housing about an axle disposed perpendicular to the plane. The trigger rotationally couples to the axle at a trigger bracket that fixedly coupled to a frame. A guide integrated in the frame engages a member extending from the trigger to manage trigger motion. A cover couples to the frame and separate from the trigger to enhance housing robustness.

  • Patent number: 11278673
    Abstract: A recording device for injection device includes a housing, a viewing window, a photographic module, a light splitting element and a signal transmission device. The housing is removably mounted on a dose scale window of an injection device. The viewing window is formed on a surface of the housing, and a viewing path is formed from the viewing window to the dose scale window. The photographic module is located on the housing, and provided with an image-capturing optical axis which is perpendicular to the viewing path. The light splitting element is located at an intersection of the viewing path and the image-capturing optical axis for guiding information located in the dose scale window to the photographic module and the viewing window, respectively. The signal transmission device is electrically connected to the photographic module for transmitting signals of the photographic module to an external device.

  • Patent number: 11260288
    Abstract: A game controller has first and second controller housings having an attachment guide structure that detachably couples to an attachment tab structure disposed on opposing sides of an information handling system and a bridge. Input devices of the controller housing communicate directly with the information handling system through opposing pins and pads disposed in the attachment features or indirectly by communicating with the bridge through opposing pins and pads so the bridge communicates with the information handling system. The attachment guide structure has opposing lips with plural slots that pass tabs of the attachment tab structure through so that a sliding motion engages the tabs behind the lips.
