    摘要: A method includes providing an LED element including a substrate and a gallium nitride (GaN) layer disposed on the substrate. The GaN layer is treated. The treatment includes performing an ion implantation process on the GaN layer. The ion implantation process may provide a roughened surface region of the GaN layer. In an embodiment, the ion implantation process is performed at a temperature of less than approximately 25 degrees Celsius. In a further embodiment, the substrate is at a temperature less than approximately zero degrees Celsius during the ion implantation process.

    摘要: The present disclosure involves a method of fabricating a light-emitting diode (LED) wafer. The method first determines a target surface morphology for the LED wafer. The target surface morphology yields a maximum light output for LEDs on the LED wafer. The LED wafer is etched to form a roughened wafer surface. Thereafter, using a laser scanning microscope, the method investigates an actual surface morphology of the LED wafer. Afterwards, if the actual surface morphology differs from the target surface morphology beyond an acceptable limit, the method repeats the etching step one or more times. The etching is repeated by adjusting one or more etching parameters.
