PROBLEM TO BE SOLVED: To provide a method of fabricating a zinc oxide semiconductor epilayer on a patterned gallium nitride template.SOLUTION: The method comprises the steps of: (1) growing a gallium nitride layer 103 on a substrate 101 comprising a sapphire substrate 101a at or above 1000°C; (2) patterning a SiOmask 105 into openings 107 oriented on the gallium nitride 103; (3) performing epitaxial lateral overgrowth of (ELO) gallium nitride layers by controlling crystal planes via choosing a growth temperature and a reactor, to form a gallium nitride layer 109 (template) grown through an array of the openings 107 from the gallium nitride layer 103; and (4) depositing a single crystal zinc oxide semiconductor layer 111 on the gallium nitride template.
