Patent ID: 7834368

Claim:
An light-emitting diode, comprising: a substrate; a primary stack structure being formed on the substrate; a secondary stack structure being formed on the substrate and surrounding the primary stack structure, the primary stack structure and the secondary stack structure both having a first conducting-type semiconductor layer, an illuminating layer, and a second conducting-type semiconductor layer sequentially formed on the substrate, wherein a plurality of pillar-like holes is formed in a top surface of the second conducting-type semiconductor layer of the secondary stack structure and the plurality of pillar-like holes protrudes into the first conducting-type semiconductor layer of the secondary stack structure; a transparent insulating material being filled into the plurality of pillar-like holes; and a transparent conducting layer being coated on the second conducting-type semiconductor layer of the primary stack structure, the transparent insulating material, and a surface of the second conducting-type semiconductor layer of the secondary stack structure.
