摘要： In a method for fabricating a vertical light emitting device, the separation or lift-off of the substrate from the light emitting diode structure formed thereon is facilitated by forming voids at the interface between the substrate and the light emitting diode structure where the separation or lift-off occurs. A substrate assembly contains a substrate and an epitaxial layer, and voids are formed at the interface between the substrate and the epitaxial layer in a controlled manner. A light emitting diode structure is then formed on the epitaxial layer, followed by attaching the light emitting diode structure to a superstrate, separating the substrate from the epitaxial layer, and forming a conductive layer and a contact pad in place of the substrate, so as to form a vertical light emitting device.

摘要： A three-dimensional LED structure with vertically displaced active -region includes at least two groups of vertically displaced surfaces on a non-planar substrate. The first group of surfaces are separated from the second group of surfaces by a vertical distance in the growth direction of the LED structure.

The sidewalls can be inclined or vertical and have a sufficient height so that a layer such as an n-type layer, an active -region, or a p-type layer in a first LED structure deposited on the first group of surfaces and a corresponding layer such as an n-type layer, an active-region, or a p-type layer in a second LED structure deposited on the second group of surfaces are separated by the sidewalls. The two groups of surfaces may be vertically displaced from each other in certain areas of an LED chip, while merge into an integral surface in other areas. A method for fabricating the three-dimensional LED structure is also provided.

摘要： A strain balanced active-region design is disclosed for optoelectronic devices such as light- emitting diodes (LEDs) and laser diodes (LDs) for better device performance. Lying below the active-region, a lattice-constant tailored strain-balancing layer provides lattice template for the active-region, enabling balanced strain within the active-region for the purposes of 1) growing thick, multiple-layer active-region with reduced defects, or 2) engineering polarization fields within the active-region for enhanced performance. The strain-balancing layer in general enlarges active-region design and growth windows. In some embodiments of the present invention, the strain-balancing layer is made of quaternary In x A1 y Ga 1-x-y N (0 ≤x≤ 1, 0 ≤y≤ 1, x+y≤1), whose lattice-constant is tailored to exert opposite strains in adjoining layers within the active-region. A relaxation-enhancement layer can be provided beneath the strain-balancing layer for enhancing the relaxation of the strain-balancing layer.
