    摘要: Methods for fabricating a semiconductor light-emitting diode (LED) device with increased light extraction are provided. The method generally includes applying a mask to a surface of an LED wafer, etching the surface of the LED wafer such that etched pits are formed in the surface, removing the mask, and roughening or texturing the surface of the LED wafer including the etched pits. In this manner, the surface area of the LED device may be increased when compared to a conventional LED device, and less emitted light may experience total internal reflection (TIR) according to Snell's law, thereby leading to increased light extraction.

    摘要: A method for the separation of multiple dies during semiconductor fabrication is described. On an upper surface of a semiconductor wafer containing multiple dies, metal layers are deposited everywhere except where a block of stop electroplating material exists. The stop electroplating material is obliterated, and a barrier layer is formed above the entire remaining structure. A sacrificial metal element is added above the barrier layer, and then the substrate is removed. After the semiconductor material between the individual dies is eradicated, any desired bonding pads and patterned circuitry are added to the semiconductor surface opposite the sacrificial metal element, a passivation layer is added to this surface, and then the sacrificial metal element is removed. Tape is added to the now exposed barrier layer, the passivation layer is removed, the resulting structure is flipped over, and the tape is expanded to separate the individual dies.
