Patent number: 8859311Abstract: A flip-chip light-emitting diode structure comprises a carrier substrate, a light-emitting die structure, a reflective layer, an aperture, a dielectric layer, a first contact layer and a second contact layer. The light-emitting die structure, located on the carrier substrate, comprises a first type semiconductor layer, a second type semiconductor layer and a light emitting layer. The light emitting layer is formed between the first type and the second type semiconductor layer. The reflective layer is located on the first type semiconductor layer. The aperture penetrates the light-emitting die structure. The dielectric layer covers an inner sidewall of the aperture and extends to a portion of a surface of the reflective layer. The first contact layer is disposed on the part of the reflective layer not covered by the dielectric layer. The second contact layer fills up the aperture and is electrically connected to the second type semiconductor layer.Type: GrantFiled: August 13, 2013Date of Patent: October 14, 2014Assignee: Lextar Electronics CorporationInventors: Chia-En Lee, Yan-Hao Chen
