In this thesis, a new nano-patterning method to increase productivity by trans-scalable microfabrication has been introduced, by using 3D diffuser lithography, metal electroplating, and nano imprint. There are high demands for nano-patterning from various industry fields and special applications such as nano-probe, nano-sifter, optical gratings, and so on. The conventional micro-pattering method like contact lithography with broadband light sources has fundamental limitations in sub-㎛ resolution. Various kinds of nanofabrications have been proposed to overcome the limitations, but most of them are not compatible with the conventional microfabircations and have low productivity in industry-level. Among the previously reported nanofabrications, nano imprint has high productivity. However, other advanced nanofabrications like e-beam lithography are needed to fabricate the mold having nano-patterns required in nano imprint, and that is a drawback of productivity. Therefore, nano imprint can be sufficiently productive as an industrial technology if there is any method that can fabricate the mold productively using conventional microfabrication. In this research, the nano-patterning method using 3D diffuser lithography which uses contact aligner had been proposed, and the characteristics and quality of the fabricated patterns had been verified. The fabricated patterns on the photoresist mold had been replicated into the rigid metal mold by metal electroplating. The quality and uniformity of the metal mold had been measured and verified. The metal mold had been used to make advanced nano-patterns on target with thermal nano imprint, and the final imprinted patterns had been measured and estimated. The proposed nano-patterning method had been performed with microfabrication, which is highly productive. And the feasibility of the nano imprint with the metal mold had been investigated. The resolution of patterns in nano-scale had been focused and verified during t...
