Yang Hao has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8759942
    Abstract: The present invention provides semiconductor devices and methods for fabricating the same, in which superior dielectric termination of drift regions is accomplished by a plurality of intersecting trenches with intermediate semiconductor islands. Thus, a deep trench arrangement can be achieved without being restricted by the overall width of the isolation structure.

  • Patent number: 8376295
    Abstract: A dual-layer suction cup includes an outer body, an adhesive soft inner body and an elastic unit. The outer body is made of a hard material. The adhesive soft inner body can be attached to a smooth airtight surface and a rough airtight surface, providing an adhesion effect. The elastic unit will provide elasticity in an opposite direction after being pressed, such that the chamber in the suction cup is in a vacuum state to enhance the adhesion effect. The adhesive soft inner body and the elastic unit of the present invention greatly enhance the adhesion effect.

  • Publication number: 20120085879
    Abstract: A dual-layer sucking disc includes a sucking body capable of adhering to a smooth surface. The sucking body has an annular closing surface which is a plane and disposed around the periphery of the sucking body. The sucking body has a concave bottom to form a sucking chamber. An inner soft layer is provided in the sucking chamber of the sucking body, which is capable of adhering to a rough surface. The inner soft layer is attached to the sucking chamber except the annular closing surface. The present invention can adhere to a smooth airtight surface with the annular closing surface or a rough airtight surface with the inner soft layer. The present invention is simply in configuration and can be manufactured with ease and used widely.
