  • Publication number: 20240094839
    Abstract: A display device includes a substrate, a sub-pixel on the substrate and including an organic light emitting diode, an encapsulation layer on the organic light emitting diode, and a plurality of touch electrodes on the encapsulation layer, the plurality of touch electrodes including an open area. The sub-pixel may include first and second emission areas and a first non-emission area in the open area of the plurality of touch electrodes, the first non-emission area being configured to be in a black state or to have a lower brightness than the first and second emission areas. Each of the first non-emission area and at least one of the first and second emission areas may have a shape of an octagon, a circle, an ellipse, a polygon, a triangle, a square, or a hexagon in a plan view.

  • Patent number: 11935777
    Abstract: A semiconductor device is manufactured using a support base and a filling material formed on the support base. The filling material can be a plurality of protrusions or penetrable film. The protrusions are attached to the support base with an adhesive. The protrusions have a variety of shapes such as square frustum, conical frustum, three-sided pyramid with a flat top, four-sided rectangular body, and elongated square frustum. A semiconductor wafer is disposed over the support base with the filling material extending into openings in the semiconductor wafer. The openings in the semiconductor wafer can have slanted sidewalls, or a more complex shape such as ledges and vertical projections. The filling material may substantially fill the openings in the semiconductor wafer. The protrusions may partially fill the openings in the semiconductor wafer. The protrusions occupy at least a center of the openings in the semiconductor wafer.

  • Publication number: 20230395449
    Abstract: A method for forming a semiconductor device is provided. The method include: providing a package including: a substrate; a stress absorbing layer disposed on a top surface of the substrate; an electronic component mounted on the top surface of substrate; and a first contact pad disposed on the top surface of the substrate and exposed from the stress absorbing layer; providing a mold including: a first cavity exposed from a bottom surface of the mold; and a recess formed adjacent to the first cavity; engaging the mold and the package with the first cavity over the electronic component and the recess between the electronic component and the first contact pad; and injecting encapsulation material into the first cavity to form an encapsulant over the electronic component.

  • Patent number: 11594438
    Abstract: A semiconductor manufacturing equipment has an outer case housing including a lower case extension to support a semiconductor panel. The lower case extension is fixed in position within the outer case housing. An inner case housing having an upper case extension is disposed within the outer case housing in proximity to the lower case extension. A mechanism draws the upper case extension toward the lower case extension and locks the semiconductor panel in place between the upper case extension and lower case extension. The mechanism has a cam assembly disposed above the inner case housing and operatable with a handle to rotate the cam assembly and apply pressure to the inner case housing and upper case extension to lock the semiconductor panel in place between the upper case extension and lower case extension. A spring or other elastic mechanism is disposed under the inner case housing to load the pressure.
