  • Publication number: 20220231066
    Abstract: Various embodiments of the present disclosure are directed towards an image sensor, and a method for forming the image sensor, in which an inter-pixel trench isolation structure is defined by a low-transmission layer. In some embodiments, the image sensor comprises an array of pixels and the inter-pixel trench isolation structure. The array of pixels is on a substrate, and the pixels of the array comprise individual photodetectors in the substrate. The inter-pixel trench isolation structure is in the substrate. Further, the inter-pixel trench isolation structure extends along boundaries of the pixels, and individually surrounds the photodetectors, to separate the photodetectors from each other. The inter-pixel trench isolation structure is defined by a low-transmission layer with low transmission for incident radiation, such that the inter-pixel trench isolation structure has low transmission for incident radiation.

  • Patent number: 10073503
    Abstract: A portable electronic device including a first body, a second body, a cam, and a linking rod is provided. The first body has a reaming hole. The second body has a rotating shaft movably coupled to the reaming hole in pivoting and penetrating manner. The cam is assembled to a side surface of the rotating shaft to rotate along with the rotating shaft. The linking rod has a first end and a second end opposite to each other. The first end is pivoted to the cam, and the second end is pivoted to the first body. When the second body is pivoted relative to the first body via the rotating shaft, the cam rotates along with the rotating shaft and the linking rod drives the cam and the rotating shaft to move along the reaming hole so as to move the second body towards or away from the first body.

  • Patent number: 9429996
    Abstract: A cover assembly including a first and second covers, a latch, an elastic unit, and fasteners is provided. The first cover has inner and outer surfaces, wherein first limiting elements, a hook, and a rail are formed on the inner surface, and keyholes are formed through the inner and outer surfaces. The second cover fixed on the first cover with the inner surface facing the second cover has a stud and second limiting elements overlapping the first limiting elements. The elastic unit connected between the latch disposed in the rail and having third limiting elements and the hook applies a restoring force to the latch. The fasteners pass through the keyholes into the stud. The latch is constrained by the fasteners to drive the third limiting elements to pass through the overlapping portions of the first and second limiting elements, and thereby the first and second covers are fixed together.

  • Patent number: 9354669
    Abstract: An electronic device includes a first body, a second body, and a linking assembly. The first body has a first side and a second side opposite to each other, and a sliding slot located at the first side. The first body and the second body are pivoted to the linking assembly. The second body rotates relative to the first side of the first body to open or close and drives the linking assembly, such that the electronic device stands on a platform with the first side or the second side of the first body. The linking assembly has a supporting block movably coupled to the sliding slot. When the second body rotates to an angle relative to the first side, the supporting block protrudes out of the first side so that the electronic device stands on the platform with the first side.
