    摘要: The invention provides a method for forming a light emitting device. A first substrate is provided. A plurality of patterned masks is formed on the first substrate, or on a semiconductor epitaxial layer grown on the first substrate, or the first substrate is etched to form a plurality of trenches, followed by performing an epitaxial lateral overgrowth process to grow an epitaxy layer over the first substrate. A light emitting structure is formed on the epitaxy layer. A first electrode layer is formed on the light emitting structure. The light emitting structure is wafer bonded to a second substrate. A photoelectrochemical etching process is performed to lift off the first substrate from the epitaxy layer.
