    摘要: A method of forming a light-emitting diode (LED) device and separating the LED device from a growth substrate is provided. The LED device is formed by forming an LED structure over a growth substrate. The method includes forming and patterning a mask layer on the growth substrate. A first contact layer is formed over the patterned mask layer with an air bridge between the first contact layer and the patterned mask layer. The first contact layer may be a contact layer of the LED structure. After the formation of the LED structure, the growth substrate is detached from the LED structure along the air bridge.

    摘要: A system and method for manufacturing an LED is provided. A preferred embodiment includes a substrate with a distributed Bragg reflector formed over the substrate. A photonic crystal layer is formed over the distributed Bragg reflector to collimate the light that impinges upon the distributed Bragg reflector, thereby increasing the efficiency of the distributed Bragg reflector. A first contact layer, an active layer, and a second contact layer are preferably either formed over the photonic crystal layer or alternatively attached to the photonic crystal layer.

    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: Semiconductor wafer dicing methods are disclosed. These methods include forming etch patterns between adjacent semiconductor dice to be separated. Various etch processes can be used to form the etch patterns. The etch patterns generally reach a pre-determined depth into the wafer substrate significantly beyond the wafer top layer where pre-fabricated semiconductor dice are embedded. Semiconductor dice may be separated from a post-etch, large-sized, frangible wafer through wafer grinding, mechanical cleaving, and laser dicing approaches. Preferred embodiments result in reduced wafer-dicing related device damage and improved product yield.
