Abstract:
1. A gallium nitride epitaxial growth method, comprising the steps of: (1) providing a semiconductor laminated layer or a heterogeneous substrate; (2) forming a platform on the semiconductor laminated layer or the heterogeneous substrate to serve as a use of a flexible nano-imprint; (3) forming a nano-pillar or a nano-hole on the semiconductor laminated layer or the heterogeneous substrate; and (4) forming a heterogeneous epitaxy region on the semiconductor laminated layer or the heterogeneous substrate; wherein the step (3) of forming the nano-pillar or the nano-hole comprises: (i) using the flexible nano-imprint with a predetermined period on the semiconductor laminated layer or the heterogeneous substrate; (ii) performing a dry-etching process once on the semiconductor laminated layer or the heterogeneous substrate to transfer print a nano-pattern; and (iii) performing a peel off process so that the nano-pattern forms the nano-pillar or the nano-hole on the semiconductor laminated layer or the heterogeneous substrate.
