| 摘要 |
The present invention discloses a method for production of selective growth masks using imprint lithography. The method includes steps of: providing a sapphire substrate, forming a GaN layer, an insulation layer, and a photo-resistive layer, performing imprint lithography, performing exposure and development, performing dry etching, and removing the remained photo-resistive layer. The selective growth masks produced by the method of the present invention make the growth of nanowires cylindrical and perpendicular to the GaN layer, and each nanowire is parallel to one another.
