Abstract:
1. A method of fabricating a ZnO film having a matching crystal orientation to a silicon substrate, comprising steps of: (a) obtaining a silicon substrate having a (111) crystal orientation, filling in a carrier gas, and running a thermal etching process on said silicon substrate by using a HCl gas; (b) filling in a carrier gas, transferring a III-group feedstock gas having Al and a V-group feedstock gas having nitrogen N (c) filling in a carrier gas, transferring a III-group feedstock gas having Al and Ga and a V-group feed stock gas having N (d) filling in a carrier gas, transferring a III-group feedstock gas having Ga and a V-group feedstock gas having N (e) filling in a carrier gas, transferring a III-group feedstock gas having In and Ga and a V-group feedstock gas having N (f) filling in a carrier gas, transferring chemical-reaction feedstock gases onto said In (g) putting said LT-ZnO/In (h) filling in a carrier gas, transferring chemical-reaction feedstock gases onto said LT-ZnO/In Wherein, through said epitaxies at high and low temperatures, layers of HT-ZnO/LT-ZnO obtain a matching single-crystal lattice to said silicon substrate.
