Abstract:
1. A light emitting diode (LED) structure, comprising: a first substrate having a first surface and a second surface; an adhering layer formed on the first surface; at least two first ohmic contact layers formed on the adhering layer; at least two epi-layers wherein a first trench is formed between each two adjacent said epi-layers, and each said epi-layer includes: a lower cladding layer formed on one of said first ohmic contact layers; an active layer formed on the lower cladding layer; and an upper cladding layer formed on the active layer; a first isolation layer covering exposed surfaces of the one of said first ohmic contact layers and the upper cladding layers, and formed between each two adjacent said first ohmic contact layers, wherein the first isolation layer has first openings and second openings formed at the exposed surfaces of the upper cladding layers and the first ohmic contact layers, respectively; at least two first electrically conducting plates, each formed in one said first opening and electrically connected to one said upper cladding layer; and at least two second electrically conducting plates, each formed in one said second opening and electrically connected to one of said first ohmic contact layers.
