  • Patent number: 10957830
    Abstract: Monolithic LED chips are disclosed comprising a plurality of active regions on a submount, wherein the submount comprises integral electrically conductive interconnect elements in electrical contact with the active regions and electrically connecting at least some of the active regions in series. The submount also comprises an integral insulator element electrically insulating at least some of the interconnect elements and active regions from other elements of the submount. The active regions are mounted in close proximity to one another to minimize the visibility of the space during operation. The LED chips can also comprise layers structures and compositions that allow improved reliability under high current operation.
    Type: Grant
    Filed: March 1, 2019
    Date of Patent: March 23, 2021
