  • Patent number: 10177277
    Abstract: In a flip chip type light-emitting diode, a light-emitting diode structure possesses one unique layer with properties of both thermal conduction and electrical isolation disposed on its second contact metal layer. A first dielectric layer covers the light-emitting diode structure. A first-level metal interconnect is divided into three blocks, which are disposed on the first dielectric layer and are respectively connected to a first contact metal layer, the second contact metal layer, and the insulated heat-transfer layer. A first bonding pad structure, a second bonding pad structure, and a heat-dissipating pad structure, forming a second-level interconnect metal layer, are disposed on a second dielectric layer and respectively connected to the blocks of the first-level metal interconnect.
