20130285098 | PATTERNED SUBSTRATE AND LIGHT EMITTING DIODE STRUCTURE - A patterned substrate includes a substrate and a plurality of protrusions. The protrusions are formed on the substrate. Each protrusion has a top face and a base. Each pair of immediately adjacent protrusions is minimally parted by 0 to 0.2 μm. When the distance between the adjacent protrusions falls as 0 μm, the bases thereof contact each other. A horizontal and a vertical light emitting diode structures using the patterned substrate are also discussed. | 10-31-2013 |
20130181240 | COMPOSITE SUBSTRATE, MANUFACTURING METHOD THEREOF AND LIGHT EMITTING DEVICE HAVING THE SAME - The present invention relates to a manufacturing method of a composite substrate. The method includes the steps of: providing a substrate; providing a precursor of group III elements and a precursor of nitrogen (N) element alternately in an atomic layer deposition (ALD) process or a plasma-enhanced atomic layer deposition (PEALD) process so as to deposit a nitride buffer layer on the substrate; and annealing the nitride buffer layer on the substrate at a temperature in the range of 300° C. to 1600° C. | 07-18-2013 |
