Light-emitting diode device with a double-layer contact structure and a fabrication method thereof

摘要

The present invention provides a light-emitting diode (LED) device and a fabrication method thereof. The LED device has a double-layered contact layer structure with a surface of one contact layer being patterned to increase ohmic contact area of the double-layered contact layer structure to lower an operation voltage of the LED device, and hence reducing power consumption.
