Light emitting diode structure

A light emitting diode structure comprising:

• a first electrode;
• a second electrode;
• and
• an epitaxial structure, the epitaxial structure divided into a base area and a structural supporting area, the base area comprising a bottom portion and a top portion, the bottom portion being wider than the top portion, the top portion protruding from a surface of the bottom portion along a single direction, the structural supporting area protruding from the surface of the bottom portion beside the top portion along the same single direction, the light emitting diode structure being substantially circular, the structural supporting area being annular and surrounding the top portion, a top of the structural supporting area aligned with a top of the top portion, the structural supporting area defining at least one slot parallel to a center axis of the light emitting diode structure, the bottom portion forming a bottom of each slot, the first electrode arranged on and electronically connected to the top of the top portion, the second electrode arranged at and electrically connected to the bottom of the slot and further arranged on the top of the structural supporting area, the second electrode arranged on the top of the structural supporting area forming an electrode contacting region, which is aligned with the first electrode, the second electrode arranged at the bottom of the slot forming a current injection region, the electrode contacting region and the current injection region have different heights.
