  • Patent number: 11916110
    Abstract: Embodiments of the present disclosure provide a method for forming semiconductor device structures. The method includes forming a fin structure having a stack of semiconductor layers comprising first semiconductor layers and second semiconductor layers alternatingly arranged, forming a sacrificial gate structure over a portion of the fin structure, removing the first and second semiconductor layers in a source/drain region of the fin structure that is not covered by the sacrificial gate structure, forming an epitaxial source/drain feature in the source/drain region, removing portions of the sacrificial gate structure to expose the first and second semiconductor layers, removing portions of the second semiconductor layers so that at least one second semiconductor layer has a width less than a width of each of the first semiconductor layers, forming a conformal gate dielectric layer on exposed first and second semiconductor layers, and forming a gate electrode layer on the conformal gate dielectric layer.

  • Patent number: 11335123
    Abstract: A live facial recognition method includes projecting a given pattern to a subject under recognition; capturing a reflected pattern of the subject under recognition; and detecting whether the subject under recognition is a flat surface according to the reflected pattern. The subject under recognition is determined to be a living subject when the subject under recognition is not a flat surface.

  • Patent number: 11126829
    Abstract: A live facial recognition method includes capturing a plurality of images of a face of a subject under recognition; obtaining time-varying data according to the images, the time-varying data representing a periodic variation of facial color of the subject under recognition due to facial vasoconstriction and vasodilation caused by heartbeat; and comparing the time-varying data with a predetermined frequency range. The subject under recognition is determined to be a living subject when the time-varying data is within the predetermined frequency range.

  • Patent number: 9706133
    Abstract: An image processing method is provided. The method includes following steps. Firstly, a first image is obtained by shooting photo at a first shutter speed, wherein the first image includes a first object image and a first background image, and the first object image and the first background image are clear. Next, a second image is obtained by shooting photo at a second shutter speed lower than the first shutter speed, wherein the second shutter speed is lower than the first shutter speed, the first image and the second image are obtained by shooting photo within substantially the same shooting range, the second image includes a second object image and a second background image, the second object image is blurry but the second background image is clear. After that, a third image is generated from at least the first image and the second object image.

  • Patent number: 9652866
    Abstract: An image processing method is provided. A first image is obtained at a first time point, the first image includes a first object image and a first background image, the first object image corresponds to the position of an object at the first time point. A second image is obtained at a second time point, the second image includes a second object image and a second background image, the second object image corresponds to the position of the object at the second time point, and the first and the second images are shot within substantially the same shooting range. A sum motion vector of the object is obtained according to the first and the second object images. The second object image is kept, and a process is applied to each pixel of the second background image in the second image to generate a third image.
