    摘要： A semiconductor device having light-emitting diodes (LEDs) formed on a concave textured substrate is provided. A substrate is patterned and etched to form recesses. A separation layer is formed along the bottom of the recesses. An LED structure is formed along the sidewalls and, optionally, along the surface of the substrate between adjacent recesses. In these embodiments, the surface area of the LED structure is increased as compared to a planar surface. In another embodiment, the LED structure is formed within the recesses such that the bottom contact layer is non-conformal to the topology of the recesses. In these embodiments, the recesses in a silicon substrate result in a cubic structure in the bottom contact layer, such as an n-GaN layer, which has a non-polar characteristic and exhibits higher external quantum efficiency.

    摘要： A method of forming a circuit structure includes providing a substrate; forming recesses in the substrate; forming a mask layer over the substrate, wherein the mask layer covers non-recessed portions of the substrate, with the recesses exposed through openings in the mask layer; forming a buffer/nucleation layer on exposed portions of the substrate in the recesses; and growing a group-III group-V (III-V) compound semiconductor material from the recesses until portions of the III-V compound semiconductor material grown from the recesses join each other to form a continuous III-V compound semiconductor layer.
