Abstract:
1. A manufacturing method of a high-efficiency light-emitting diode (LED), comprising: cleaning a soft mold and an LED wafer having a hydrophilic surface; coating a demolding agent on a pattern surface of the soft mold; coating an imprinting material on the pattern surface of the soft mold so that a first surface of the imprinting material is closer to the soft mold than any other surface of the imprinting material; after the coating, bonding the imprinting material to the hydrophilic surface of the LED wafer with a second surface of the imprinting material disposed opposite to the first surface to perform pattern transfer, wherein a hydrophilicity exists between the imprinting material and the LED wafer; solidifying the imprinting material to form a pattern thereupon that is transferred from the soft mold; and demolding the soft mold from the pattern transferred imprinting material so that the LED wafer remains connected with the pattern transferred imprinting material.
