LED Structure

An 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 each said epi-layer includes:
• a lower cladding layer formed on one said first ohmic contact layer;
• an active layer formed on the lower cladding layer;
• an upper cladding layer formed on the active layer;
• and
• a second trench vertically passing through the upper cladding layer and the active layer and entering a part of the lower cladding layer;
• a second isolation layer covering the upper cladding layers and formed between each two adjacent said epi-layers and between each two adjacent said first ohmic contact layers, wherein the second isolation layer has a third opening formed on each said upper cladding layer and a fourth opening formed at an inner side of each said second trench;
• at least two fifth electrically conducting plates, each formed in one said third opening and electrically connected to one said upper cladding layer;
• and
• at least two sixth electrically conducting plates, each formed in one said fourth opening, having an extending portion extending downward to vertically pass through the epi-layer and electrically connect with the first ohmic contact layer.
