- 詳細技術說明
- Researchers led by Paul Weiss from the Department of Chemistry and Biochemistry at UCLA have developed a novel technique that solves the scalability issue in the fabrication of three-dimensional nanostructures. This work builds upon nanosphere lithography to allow for multiple uses of the nanosphere layer to create a variety of three dimensional structures. This allows the user to create and specify structures with different inner/outer diameters, heights/hole depths, and pitches. These new capabilities allow for the creation of variable and unique nanostructures while still enjoying the benefits of nanosphere lithography including high throughput and low cost.

Background
Configurable three-dimensional nanostructures have a wide range of applications spanning electronics, biotechnology, and optics due to favorable optical, electrical, mechanical properties as well as biocompatibility. However, issues of scalability and configurability prevent mass adoption of this technology. Current fabrication of nanostructures uses lithographic techniques using lasers and nanospheres. Lithographic techniques that use lasers, like electron-beam lithography, have higher costs, more complexity, and lower throughput than nanosphere lithography. Nanosphere lithography uses a layer of patterned nanospheres that act as a mask so that the surrounding material can be etched away forming 3D structures. However, this technique is limited in that each layer of nanospheres can only be used once, limiting the types of shapes that can be made. Multiple uses of this nanosphere layer would allow for the fabrication of structures that are more complex and desirable.
