SNM: DNA-Directed Self Assembly of Nanoscale Integrated Circuits

这项可扩展纳米制造 (SNM) 赠款为建立纳米级电子电路元件的大规模并行和高吞吐量制造方法提供了资金。首先，合理设计的分子构件将被合成，并将它们按照预定的排列组装在类似DNA的模板上，形成有机半导体纳米线。经商业验证的技术，例如纳米压印光刻，将用于制备分子面包板。随后，将利用 DNA 的模板和自组装特性在这些面包板上形成纳米线阵列。作为这项努力的一部分，工业和学术合作者将合作建立一个纳米级制造暑期学校，为学生和研究人员提供我们开发的技术培训。半导体行业生产的电子设备不仅推动大多数现代技术，而且推动全球经济。由于传统光刻制造技术的局限性，该行业已经确定了对未来纳米级电子产品的可扩展纳米制造的迫切需求。尽管研究人员已经展示了分离分子电子器件的非凡例子，但此类器件的可扩展生产仍处于停滞状态，因为它们的活性组件无法以任意精度或高产量组装。通过有机化学、生物自组装和自上而下的纳米制造的跨学科组合，将制备出具有合理设计的电性能的有机纳米线，并在固体基底上组装此类结构的阵列。这种方法将使下一代纳米级集成电路元件能够以可重复的方式和低成本制造。

This Scalable NanoManufacturing (SNM) grant provides funding to establish a methodology for the massively parallel and high throughput manufacture of nanoscale electronic circuit elements. First, rationally designed molecular building blocks will be synthesized and assemble them in predetermined arrangements on DNA-like templates, forming organic semiconductor nanowires. Commercially validated techniques, such as nanoimprint lithography, will be used to prepare molecular bread boards. Subsequently, the templating and self-assembly properties of DNA to form arrays of nanowires at these bread boards will be leveraged. As part of this effort, industrial and academic collaborators will partner to establish a nanoscale manufacturing summer school for training students and researchers in the techniques that we develop.The semiconductor industry produces electronic devices that drive not only most modern technologies but also the global economy. Due to the limitations of traditional lithographic manufacturing techniques, this industry has identified a crucial need for the scalable nanomanufacturing of futuristic nanoscale electronics. Although researchers have demonstrated remarkable examples of isolated molecular electronic devices, the scalable production of such devices remains at a standstill because their active components cannot be assembled with arbitrary precision or in high yield. Through an interdisciplinary combination of organic chemistry, biological self-assembly, and top-down nanofabrication, organic nanowires will be prepared with rationally designed electrical properties and assemble arrays of such constructs at solid substrates. This approach will enable the fabrication of the next generation of nanoscale integrated circuit elements in reproducible fashion and at low cost.
