This Boosting Research Ideas for Transformative and Equitable Advances in Engineering (BRITE) Synergy award will support research which seeks to transform the way manufacturers perform electron-beam lithography by introducing a reactive gas that modifies the process chemistry. Electron-beam lithography is critical for nearly all manufacturing at nanometer length scales and is often the first step in fabricating devices in semiconductor electronics, digital imaging, communications, and healthcare. This innovation will enable patterning of new functional materials while also improving the performance of conventional materials. The research program seeks to understand the fundamental physical and chemical mechanisms underlying the effects of reactive gases on the lithographic process, and to use this knowledge to advance lithographic performance. A broad range of industries now relies on nanoscale manufacturing, and thus on electron-beam lithography. This award could thus impact multiple sectors of the U.S. economy while accelerating product development and increasing access to nanotechnology-enabled products. This effort will also expand diversity, equity, and inclusion in advanced manufacturing through workshops for middle-school teachers primarily serving underrepresented groups and multi-disciplinary training for graduate students recruited from underrepresented groups. Electron-beam lithography is the primary pattern generation technology for nearly all nanomanufacturing, from integrated circuit mask making to direct-writing of quantum devices. Focused electron-beam induced processing in gases and liquids provides nanoscale rapid prototyping with functional materials as well as nanoscale repair and editing capabilities. This effort synthesizes research outcomes in these two areas with established knowledge in radiation chemistry and electron-material interactions to enhance understanding of the influence of reactive gases on electron-beam lithography. Specifically, the research seeks to understand how reactive gases can alter radiation chemical processes to expand the range of materials that can be patterned and to improve lithographic performance for conventional electron-beam resists. A rigorous research synthesis program, Hybrid Monte Carlo-continuum simulations, and carefully designed nanopatterning experiments will build knowledge of the relationships between process conditions, such as gas composition and pressure, and lithographic performance metrics, such as sensitivity, contrast, and resolution. Success could transform electron-beam lithography because functional materials could be patterned with resolution and throughput comparable to conventional resists while the performance of conventional resists could be tuned by the reactive gas.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项促进工程转型和公平进步的研究想法奖(BRITE)协同奖将支持寻求通过引入改变过程化学的反应气体来改变制造商执行电子束光刻的方式的研究。电子束光刻对几乎所有纳米尺度的制造都至关重要，通常是制造半导体电子、数字成像、通信和医疗保健设备的第一步。这一创新将使新功能材料的图案化成为可能，同时还可以改善传统材料的性能。该研究计划旨在了解反应气体对光刻过程影响的基本物理和化学机制，并利用这些知识来提高光刻性能。许多行业现在都依赖于纳米级的制造，因此也依赖于电子束光刻技术。因此，这一奖项可能会影响美国经济的多个部门，同时加快产品开发，增加获得纳米技术产品的机会。这一努力还将通过为主要服务于代表性不足群体的中学教师举办讲习班，以及为从代表性不足群体招聘的研究生进行多学科培训，来扩大多样性、公平性和对先进制造业的包容性。电子束光刻是几乎所有纳米制造的主要图形生成技术，从集成电路掩模制造到量子器件的直接写入。聚焦电子束在气体和液体中的诱导处理为纳米级快速成型提供了功能材料以及纳米级修复和编辑能力。这项工作利用辐射化学和电子-材料相互作用方面的既定知识，综合了这两个领域的研究成果，以加强对反应气体对电子束光刻的影响的了解。具体地说，这项研究试图了解反应气体如何改变辐射化学过程，以扩大可图案化材料的范围，并改善传统电子束抗蚀剂的光刻性能。严谨的研究合成计划、混合蒙特卡罗连续谱模拟和精心设计的纳米粒子实验将建立工艺条件(如气体组成和压力)与光刻性能指标(如灵敏度、对比度和分辨率)之间的关系的知识。成功可以改变电子束光刻技术，因为功能材料的图案化分辨率和产量可以与传统抗蚀剂相媲美，而传统抗蚀剂的性能可以通过反应气体进行调整。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
