EPSRC Fellowships in Manufacturing: Additive nanomanufacturing via probe-based pick-and-place nanoparticle assembly

东京联合国大学估计，平均每2克硅芯片需要消耗1.6公斤化石燃料、73克化学品和32公斤水。这主要是因为迄今为止使用的纳米制造技术是一种逐层添加和减去的过程。到目前为止，纳米制造的创新主要集中在减小特征尺寸上，现在已经达到非常小的尺寸;进一步的缩放不一定会提高性能。这开启了更新现有电子设备的可能性，因为功能而不是缩放（或特征尺寸节点）是主要驱动力。同时，在学术界，对纳米颗粒自组装的研究也引起了人们的兴趣。这些技术对于理解如何使用化学使粒子以预定的模式排列非常重要。在这个奖学金，我打算推进这些发展对定向，添加剂纳米制造技术使用纳米探针，以挑选和放置纳米粒子。拟议的研究旨在让纳米级机械臂拾取和放置纳米颗粒，以制造具有更高功能的新设备，更新纳米级设备，并减少纳米制造中产生的减法废物。

The United Nations University in Tokyo estimates that an average 2g silicon chip costs 1.6kg of fossil fuel, 73g of chemicals and 32 kg of water. This is primarily because the nanomanufacturing technology used thus far is a layer-by-layer additive and subtractive process. Innovations thus far in nanomanufacturing have focused mostly on reducing feature sizes, which have now reached remarkably small dimensions; further scaling will not necessarily deliver increased performance. This opens up the possibility of updating existing electronics, as functionality rather than scaling (or the feature size node) is the main driver. Meanwhile in academia, considerable research into self-assembly of nanoscale particles has also been of interest. These techniques have been very important in understanding how to use chemistry to make particles arrange themselves in pre-determined patterns. In this fellowship, I intend to advance these developments towards a directed, additive nanomanufacturing technique using nanoscale probes to pick and place nanoparticles. The proposed research aims to have nanoscale robotic arms picking and placing nanoparticles to manufacture new devices with increased functionality, update nanoscale devices and to reduce the subtractive waste generated in nanomanufacturing.
