Abstract:
A method for transferring a device includes the following steps: forming a pliable adhesive layer on a carrier substrate; placing the device over the pliable adhesive layer; contacting a transfer head assembly with the device, in which a pliable dielectric layer of the transfer head assembly is in contact with the device during the contacting and more pliable than the device, such that the pliable dielectric layer of the transfer head assembly deforms during the contacting, and the pliable adhesive layer is more pliable than the device, such that the pliable adhesive layer deforms during the contacting; actuating the transfer head assembly to create a grip force; picking up the device by the grip force created by the transfer head assembly; and placing the device onto a receiving substrate.
