  • Optoelectronic device and the manufacturing method thereof
    Patent number: 10749077
    Abstract: An optoelectronic device includes a semiconductor stack including a first surface and a second surface opposite to the first surface; a first contact layer on the first surface; and a second contact layer on the second surface. The second contact layer is not overlapped with the first contact layer in a vertical direction. The second contact layer includes a plurality of dots separating to each other and formed of semiconductor material.
    Type: Grant
    Filed: December 20, 2018
    Date of Patent: August 18, 2020
    Assignee: EPISTAR CORPORATION
