  • Manufacturing method of high-efficiency LED
    Patent number: 8530251
    Abstract: A manufacturing method of a high-efficiency light-emitting diode (LED) is provided. A soft mold is used to transfer a microstructure or a nano-scale pattern thereon onto an imprinting material. The imprinting material is distributed all over an LED wafer; and the imprinting process may be performed through forward imprinting or reverse imprinting.
    Type: Grant
