High Performance Embedded Passive Components Based on Novel Ultrahigh-K and Ultrahigh-Q Nanocomposites for Microelectronics Systems

本研究的目的是从根本上了解新型聚合物基低温加工超高k和高q纳米复合材料的电、介电和磁性行为，并探索其在嵌入式无源器件中的应用。该方法是研究和优化炭黑与其聚合物基体之间的界面，以降低超高k（13000）聚合物/炭黑复合材料的介电损耗。介质损耗可以通过炭黑表面改性/处理、螯合剂包合、库仑阻断效应等多种方法来控制。另一种方法是合成和研究具有不同钝化性质的核壳结构纳米颗粒，模拟填充自钝化铝颗粒的超高k纳米复合材料。对于高q嵌入式电感，方法是合成和研究纳米相铁磁和软铁磁颗粒，并研究其复合材料作为高频应用的核心材料。本研究对聚合物基低加工温度超高k和高q纳米复合材料的基本理解将成为下一代电子产品低成本高性能组件应用的关键使能技术。这项技术可以很容易地转移到工业上。这肯定会加快微电子工业的发展步伐，并在美国保留大量的高科技工作岗位。拟议的研究还产生了更广泛的影响，包括在大学预科、本科和研究生阶段招募和指导学生，特别是那些在研究和教育活动中代表性不足的群体。PI将继续向大亚特兰大地区提供资源，重点关注那些代表性不足的群体。

The objective of this research is to fundamentally understand the electric, dielectric and magnetic behaviors of novel polymer-based low-processing temperature ultrahigh-k and high-Q nanocomposites and to explore their applications in embedded passive components. The approach is to study and optimize the interfaces between carbon black and its polymer matrix to reduce the dielectric loss of ultrahigh-k (13,000) polymer/carbon black composites. The dielectric loss will be controlled by various methods such as carbon black surface modification/treatment, and chelating agent inclusion, and Coulomb blockade effects. Another approach is to synthesize and study the core-shell structured nanoparticles with various passivation natures, mimicking ultrahigh-k nancomposites filled with self-passivation aluminum particles. For high-Q embedded inductors, the approach is to synthesize and study nanophase ferromagnetic and soft ferromagnetic particles and investigate their composites as the core material for high-frequency applications.The fundamental understanding of the polymer-based low-processing temperature ultrahigh-k and high-Q nanocomposites from this prosposed research will be a key enabling technology for the application of low cost and high performance components for next-generation electronics. This technology can be readily transferred to industry. This will certainly speed up the pace of microelectronic industry, and retain numerous high tech jobs in the US. The broader impacts also resulting from the proposed research include recruiting and advising students at pre-college, undergraduate and graduate levels, especially those from the underrepresented groups in the research and education activities. The PI will continue his practice of providing resources to the greater Atlanta area with an emphasis on those underrepresented groups.
