Nanosphere lithography is an efficient way to fabricate metallic nanostructures with large area. This paper presents the fabrication of metallic hexagonal nano-pyramid arrays by two dimensional nanospheres lithography assisted with O2 plasma treatment. By O2 plasma treatment, the gap and diameter of nanospheres can be modulated. After electron beam deposition, we can fabricate similar nanostructures with different pyramid gap distances. This method may be an easy way to modulate the geometric parameters of nanostructures.
