Nanomanufacturing Using Solder Based Three Dimensional Self-Assembly

当今的纳米图案化技术本质上是二维的，构建任意图案化的三维纳米级组件是极具挑战性的。这项提议寻求开发一种简单和高通量的策略来制造这些精确图案化和单分散的纳米级组件。具体地说，将要开发的拟议策略涉及二维光刻图案化模板的自组装，以形成三维的、无拴系的多面体组件。除了展示该工艺在100纳米尺度上的适用性外，还将进行旨在了解缺陷容限和影响总产量的参数的调查。提出的低成本、大规模生产具有任意图案的纳米组件将使人们能够构建广泛的小型化和更有效的器件，用于纳米电子、生物分子成像、药物输送、传感和致动等应用。此外，该工艺与当今微芯片的制造兼容；因此，该工艺允许在组件内无缝集成电子模块，如晶体管和传感器。除了这项研究，还将共同努力加强巴尔的摩高中的本科生教育和外展。本科生、高中教师和学生，包括代表性不足的少数民族，将被邀请参加研究体验。此外，还将组织旨在提高学校、大学和公众对科学、工程和纳米技术的欣赏程度的活动。

Present day nanoscale patterning techniques are inherently two dimensional and it is extremely challenging to construct arbitrary patterned three dimensional nanoscale components. This proposal seeks to develop a simple and high-throughput strategy for fabricating these precisely patterned and monodisperse nanoscale components. Specifically, the proposed strategy that will be developed involves the self-assembly of two dimensional lithographically patterned templates to form three dimensional, untethered polyhedral components. In addition to demonstrating the applicability of the process at the 100 nanometer length scale, investigations directed at understanding defect tolerance and parameters that influence overall yield will also be carried out. The proposed low-cost, mass production of nanoscale components, with arbitrary patterning will enable a wide range of miniaturized and more effective devices to be constructed for applications such as nanoelectronics, biomolecular imaging, drug delivery, sensing, and actuation. Additionally, the process is compatible with present day fabrication of microchips; hence the process allows the seamless integration of electronic modules, such as transistors and sensors, within the components. Along with the research, a concerted effort will be made to enhance undergraduate education and outreach in Baltimore high schools. Undergraduate students, high school teachers and students, including under represented minorities, will be invited to participate in research experiences. Moreover, activities directed at increasing an appreciation for science, engineering and nanotechnology in schools, colleges and to the public will be organized.
