| Outline of Research at the Start |
ナノスケールの3次元構造形成は部品組立が困難なため確立されていない．一方，3Dプリティングは組立不要で3次元構造を形成できるため，これを用いたナノ構造形成が期待されている．しかし，加工分解能は，最も高い光造形法でも光の波動性による原理限界により100nm程度が限界である．本研究では，ナノ厚さ液膜特有の性質に着目し，近接場光加工を2次元表面加工から3次元積層加工に拡張する方法を提案し原理確認を試みる．

| Outline of Final Research Achievements |
In this study, we tried to establish the basic technology for nano-3D structure formation by extending near-field optical fabrication from two-dimensional to three-dimensional processing. We have proposed and successfully demonstrated an original method for nano-thickness liquid film lamination, which is a key technology for realizing the nano-3D structure formation. In this method, we focused on the molecular interaction between the liquid film and the substrate surface, which provides unique properties of nano-thick liquid films.
