Abstract
A method of transferring a semiconductor light emitting device, and which includes positioning a transfer head having a head electrode facing a semiconductor light emitting device having an undoped semiconductor layer, the semiconductor light emitting device arranged on a carrier substrate; moving the head electrode of the transfer head close to the undoped semiconductor layer of the semiconductor light emitting device; applying a voltage to the head electrode to provide an attachment force to the undoped semiconductor layer by an electrostatic force; and picking-up the semiconductor light emitting device and transferring the semiconductor light emitting device to base substrate.
