摘要： A light-emitting diode (LED) structure and a method for manufacturing the same. The LED structure comprises an insulating substrate, a plurality of LED chips and a plurality of interconnection layers. Each LED chip comprises a first conductivity type semiconductor layer, an active layer and a second conductivity type semiconductor layer stacked in sequence on a surface of the insulating substrate. Each LED chip includes a mesa structure, an exposed portion of the first conductivity type semiconductor layer adjacent to the mesa structure, and a first isolation trench. The first isolation trench is disposed in the mesa structure. The interconnection layers respectively connect neighboring two of the LED chips.

摘要： A periodically structured substrate includes a slab and a periodic structure formed on the slab and including a plurality of spaced apart first surrounding elements and a plurality of spaced apart central elements. The first surrounding elements are periodically arranged in such a manner to form repeating polygonal patterns. Each of the central elements is disposed at a center of a respective one of the polygonal patterns. The periodic structure further includes a spacer medium that fills a space among the central element and the first surrounding elements of each of the polygonal patterns and that has a refractive index different from those of the central element and the first surrounding elements.
