摘要: Exemplary embodiments of the present invention provide light emitting diode (LED) chips and a method of fabricating the same. An LED chip according to an exemplary embodiment includes a substrate; a light emitting structure arranged on the substrate, and an alternating lamination bottom structure arranged under the substrate. The alternating lamination bottom structure includes a plurality of dielectric pairs, each of the dielectric pairs including a first material layer having a first refractive index and a second material layer having a second refractive index, the first refractive index being greater than the second refractive index.
