Abstract: 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.

In an embodiment of the invention, a group-III nitride film is grown on a surface of a lower layer. The nitride film is grown by first epitaxially growing a group-III metal film on the surface in a substantially nitrogen-free atmosphere.

This process can be repeated one or more times to form the layer. In another embodiment of the invention, islands are formed on a surface of a lower layer from a group-III nitride film. The islands can be used to subsequent group-III nitride growth to form the group-III nitride layer.
