Nanosphere lithography has been studied as a general fabrication method to produce periodic particle array with nanometer scale features. This paper presents the first sub-100 ㎚ nanosphere lithography (NSL) with an optimized spin coating condition and a nano template structure. The spin coating condition was tuned to obtain the best possible crystal formation. The qualities of the crystal domain, i.e., regularity and coverage, were further improved when a nano-trench structure was used as a template. We demonstrate a sub-100 ㎚ nanohole array over 1㎟ area with subsequent fabrication steps.
