ABSTRACT:
An LED structure includes a first substrate; an adhering layer formed on the first substrate; first ohmic contact layers formed on the adhering layer; epi-layers formed on the first ohmic contact layers; a first isolation layer covering the first ohmic contact layers and the epi-layers at exposed surfaces thereof; and first electrically conducting plates and second electrically conducting plates, both formed in the first isolation layer and electrically connected to the first ohmic contact layers and the epi-layers, respectively. The trenches allow the LED structure to facilitate complex serial/parallel connection so as to achieve easy and various applications of the LED structure in the form of single structures under a high-voltage environment.
