项目摘要

As predicted by Moore's "law", the past few decades have seen massive reductions in the size of integrated circuits, enabling the portable, handheld devices now in everyday use. However, the components that power these devices have not experienced a similar size reduction. For example, the power adapter of a laptop computer is only modestly smaller than that two decades ago, and the printed circuit board inside a smart phone must dedicate between 20% and 40% of the board area for power conversion and management. To date, efforts towards miniaturization have been limited by both materials and manufacturing challenges. To address this gap, this research will study nanomanufacturing processes to facilitate the scalable synthesis of high quality magnetic nanoparticles and nanocomposite core materials and the fabrication of compact power inductors and transformers through assembly of these nanomaterials in a manner that is compatible with current manufacturing processes, such as silicon wafer or printed circuit board fabrication. This compatibility will enable fully integrated and compact system-on-chip or system-in-package power solutions. This research will be accomplished by fostering collaboration among disciplines including materials science, chemical engineering and electrical engineering. It will foster diversity in the profession by involving high school and undergraduate students in research activities and by broadening participation through the inclusion and engagement of women and underrepresented groups.The overarching goal of this project is to study synthetic and nanomanufacturing processes that overcome existing integration challenges while affording breakthrough, high-frequency magnetic performance. An aim is to research materials that exhibit high magnetic saturation and low loss. This will be accomplished by leveraging the unique properties of magnetic materials at the nanoscale through a combination of nanomanufacturing approaches spanning bottom-up synthesis to directed assembly and nanocomposite formation. The specific objectives are to: (i) scale-up synthesis of high quality magnetic nanoparticles via thermal decomposition routes by elucidating the underlying correlations between synthesis parameters and nanoparticle properties, leveraging recent developments in the reproducible synthesis of near defect-free nanocrystals with magnetic properties approaching those of the bulk; (ii) study methods for large-scale directed assembly of magnetic nanoparticles via dielectrophoresis into compact power inductors/transformers; and (iii) demonstrate the formation of bi-phasic nanocomposite cores through large-scale electro-infiltration of an additional ferromagnetic material. An expected outcome of this project is to demonstrate scalability through the full-wafer batch-fabrication of microinductor devices using the developed methods on a silicon wafer. From a commercial standpoint, nanomanufacturing technologies providing process-integrable, high-performance magnetic components for power application have the potential to impact a nearly $12B/year market.

正如摩尔的“法律”所预测的那样，过去几十年来，综合电路的大小大大减少，使现在日常使用的便携式手持设备能够降低。但是，这些设备为这些设备供电的组件并未经历相似的尺寸降低。例如，笔记本计算机的电源适配器仅比二十年前小小，并且智能手机内的印刷电路板必须专用于董事会区域的20％至40％以进行电源转换和管理。迄今为止，小型化的努力受到材料和制造挑战的限制。为了解决这一差距，这项研究将研究纳米制造过程，以促进高质量磁性纳米颗粒和纳米复合核心材料的可扩展合成，以及通过与当前制造工艺相兼容的方式，通过组装这些纳米材料来制造紧凑型功率电感器和变压器，例如硅胶制造工艺，例如硅纤维制造工艺，例如硅焊料制造或打印的电路板。这种兼容性将使芯片或包装功率解决方案完全集成和紧凑。这项研究将通过促进材料科学，化学工程和电气工程等学科之间的合作来完成。它将通过让高中和本科生参与研究活动，并通过妇女的包容和参与来扩大参与的参与，从而促进该行业的多样性。该项目的总体目标是研究合成和纳米制造过程，以克服现有的集成挑战，同时具有突破性的磁性磁性，高频磁性能。一个目的是研究表现出高磁饱和度和低损失的材料。这将通过利用纳米制造方法的组合来利用纳米级的磁性材料在纳米级的独特特性来实现，从而跨越了自下而上的合成与有向组件和纳米复合材料的形成。具体目标是：（i）通过阐明合成参数与纳米粒子特性之间的基本相关性，通过热分解途径扩大高质量磁性纳米粒子的范围，利用了与近乎无缺陷的无磁性物质的可复制合成的最新发展，该磁性具有接近啤酒的磁性物质；（ii）研究方法，用于通过介电的磁性纳米颗粒将磁性纳米颗粒组装到紧凑的功率电感器/变压器中；（iii）通过大规模的电磁物质的大规模电渗透来证明双重纳米复合核心的形成。该项目的一个预期结果是通过使用硅晶片上开发的方法对微电导体设备的全块批量制作来证明可扩展性。从商业角度来看，为电力应用提供可提供流程综合性，高性能磁性组件的纳米制造技术有可能影响近12B美元/年的市场。
