    Abstract: A method for manufacturing a perpendicular LED for preventing bending of a wafer while reducing the time required for manufacturing to improve the mass production yield of perpendicular LEDs includes: growing an LED compound semiconductor structure on a sapphire substrate; forming an adhesive layer which is stacked on the LED compound semiconductor structure in the order of a first solder layer, a heat-emitting layer, and a second solder layer; forming a conductive substrate on the adhesive layer; coupling the first solder layer and the second solder layer by means of the heat which is generated from reacting the heat-emitting layer; and removing the sapphire substrate.
