LIGHT EMITTING DIODE MODULE FOR SURFACE MOUNT TECHNOLOGY AND METHOD OF MANUFACTURING THE SAME

摘要

An LED is provided to include: a first conductive type semiconductor layer; an active layer positioned over the first conductive type semiconductor layer; a second conductive type semiconductor layer positioned over the active layer; and a defect blocking layer comprising a masking region to cover at least a part of the top surface of the second conductive semiconductor layer and an opening region to partially expose the top surface of the second conductive type semiconductor layer, wherein the active layer and the second conductive type semiconductor layer are disposed to expose a part of the first conductive type semiconductor layer, and wherein the defect blocking layer comprises a first region and a second region surrounding the first region, and a ratio of the area of the opening region to the area of the masking region in the first region is different from a ratio of die area of the opening region to the area of the masking region in the second region.
