Abstract
A light-emitting diode (LED) structure and a method for manufacturing the same. The LED structure includes an insulation substrate, a plurality of LED chips and a plurality of interconnection layers. Each LED chip includes an epitaxial layer and a dielectric layer stacked on a surface of the insulation substrate in sequence. Each LED chip is formed with a first conductivity type contact hole and a second conductivity type contact hole penetrating the dielectric layer, and a first isolation trench disposed in the epitaxial layer and between the second conductivity type contact hole of the LED chip and the first conductivity type contact hole of the neighboring LED chip. Each interconnection layer extends from the second conductivity type contact hole of each LED chip to the first conductivity type contact hole of the neighboring LED chip by passing over the first isolation trench to electrically connect the LED chips.
