Abstract:
A method for transferring a micro device is provided. The method includes: preparing a carrier substrate with the micro device thereon, wherein an adhesive layer is between and in contact with the carrier substrate and the micro device; picking up the micro-device from the carrier substrate by a transfer head; forming a liquid layer on a receiving substrate; and placing the micro device over the receiving substrate by the transfer head such that the micro device is in contact with the liquid layer and is gripped by a capillary force; and moving the transfer head away from the receiving substrate such that the micro device is detached from the transfer head and is stuck to the receiving substrate.
