Abstract:
A method of manufacturing an electro-optical device, said method comprising the steps of:providing a transfer substrate comprising a growth substrate layer and an electro-optical layer which can transfer an optical signal; implanting hydrogen ions or hydrogen ions in combination with other ions in the transfer substrate to form therein an intermediate hydrogen ion implant layer, defining an electro-optical layer portion of the transfer substrate which includes at least a portion of the electro-optical layer; providing a handle substrate having a bonding surface; bonding the transfer substrate to the bonding surface of the handle substrate to form a joined structure; heating the joined structure to a temperature sufficient to split the joined structure along the hydrogen ion implant layer thereby to transfer the electro-optical layer portion of the transfer substrate to the handle substrate and to form a splitting surface on the electro-optical layer portion; and providing an electrode in association with said electro-optical layer or a portion thereof.
