  • Patent number: 11594658
    Abstract: A light-emitting element is provided, including a semiconductor structure, a reflective structure, first insulating structures, a conductive structure, and first and second pads. The reflective structure is disposed on the semiconductor structure. The first insulating structure includes first and second insulating portions covering first and second portions respectively, and a gap exposes a third portion between the first and second portions. The conductive structure includes first and second conductive portion. The first conductive portion is disposed on the first insulating portion to contact the semiconductor structure. The second conductive portion is disposed on the second insulating portion to contact the third portion through the gap. The first and second pads are respectively disposed on the first and second conductive portions. Each of the structures below the first and second pads are in flat-type bonding to enhance stress resistance.

  • Publication number: 20210280742
    Abstract: A light-emitting element is provided, including a semiconductor structure, a reflective structure, first and second insulating structures, a conductive structure, and first and second pads. The reflective structure is disposed on the semiconductor structure. The first insulating structure includes first and second protrusions covering first and second portions respectively, and a first recession exposes a third portion between the first and second portions. The conductive structure includes first and second conductive portion. The first conductive portion is disposed on the first protrusion to contact the semiconductor structure. The second conductive portion is disposed on the second protrusion to contact the third portion through the first recession. The first and second pads are respectively disposed on the first and second conductive portions. Each of the structures below the first and second pads are in flat-type bonding to enhance stress resistance.
