Seminar by Dr. Andy Lemmon of The University of Alabama
by Carte, Lori J 11 Oct '22

DATE: Tuesday, November 1, 2022, 11:00am LOCATION: WANG 1004 Enabling Next-Generation Power Electronics With Wide Band-Gap Semiconductors Dr. Andy Lemmon Associate Professor The University of Alabama During the last ten years, the maturity of wide band-gap (WBG) semiconductor technology has advanced rapidly. The most mature WBG semiconductor available today is the Silicon Carbide (SiC) MOSFET, which is now being deployed in commercial applications on a broad scale. SiC devices offer substantial performance advantages over traditional Silicon devices in terms of reduced losses, increased switching speed, and increased thermal capability. When this technology is properly implemented, these device-level performance advantages translate into converter-level and system-level benefits, such as increased efficiency and power density. For example, WBG converters have been demonstrated at ten times higher power density than legacy Silicon converters, without sacrificing conversion efficiency. In order to achieve such performance gains, SiC-based converters must be carefully optimized to take full advantage of the underlying semiconductor capabilities. Implementation of SiC-based converters using design principles developed for Silicon devices will yield sub-optimal performance. In some cases, this may produce converters that perform worse than legacy Silicon systems. Understanding the key design principles used to optimize converters for SiC devices is critical to attaining the performance entitlement of such systems. This talk will provide an overview of the concepts that must be understood to unlock the performance advantages of SiC semiconductors at the converter level. First, the characteristics of SiC devices will be explained, along with the procedures used to evaluate and quantify device-level performance. Second, guidance for implementing these devices in practical application circuits will be presented. Third, the metrology and instrumentation requirements for properly evaluating WBG converter implementations will be discussed. Fourth, future trends will be analyzed, including the challenges and opportunities associated with the implementation of medium-voltage (MV) SiC semiconductors. Case studies will be presented throughout this talk to demonstrate the concepts discussed, and to illustrate the presence of knowledge gaps that call for further investigation. Andrew N. Lemmon received the B.S. degree in electrical engineering from Christian Brothers University, Memphis, TN, USA, in 2000; the M.S. degree in electrical and computer engineering from The University of Memphis, Memphis, TN, USA, in 2009; and the Ph.D. degree in electrical engineering from Mississippi State University, Starkville, MS, USA, in 2013. >From 2000 to 2010, he was an Embedded Systems Design Engineer at FedEx Corporation in Memphis, TN, USA. From 2010 to 2013, he was a graduate research assistant in the Center for Advanced Vehicular Systems (CAVS) at Mississippi State University. He is currently an Associate Professor with the department of electrical and computer engineering at the University of Alabama, Tuscaloosa, AL, USA. His research interests include design and optimization of Silicon Carbide applications; development of compact behavioral models for power semiconductor devices; analysis, modeling, and design of power semiconductor packaging; and analysis, modeling, and mitigation of electromagnetic interference in power electronic systems. Dr. Lemmon is a Registered Professional Engineer and has been awarded four patents.

[Christopher Nordquist] Christopher Nordquist Sandia National Laboratories Monday, October 10, 2022 10:30am, WANG 1004 ABSTRACT Heterogeneous Integration for Next-Generation RF Microsystems. Heterogeneous Integration (HI) reduces size weight and power (SWaP) and provides high-density electrically short interconnect by eliminating the overhead of traditional packaging, thus enabling electronic microsystems to perform functions beyond that achievable with any single technology. A practical HI strategy must allow for a broad range of technologies and materials: state-of-the art electronics such as advanced node CMOS integrated circuits, specialty electronics such as compound semiconductor RF or power electronics, optoelectronic components in either silicon or compound semiconductors, microelectromechanical components, RF passives and antennas, high-density connectors, and advanced early-stage R&D prototypes in emerging technologies. In all cases, supply chain and economic realities force tradeoffs between realizing the smallest integrated microsystem with the tightest integration dimensions versus lower cost manufacturable approaches with somewhat relaxed interconnect densities. Given this diversity of materials and processes, our adaptable and scalable approach is to fabricate devices separately, through internal or external sources, followed by 2.5D integration of these devices onto high-density interposers. This approach allows access to a variety of technologies and components but is complicated by the dominance of the pure-play foundry model, prohibitive cost of full wafer runs, limited supplier options for given technologies, and small product quantities with limited learning cycles. To address some of these issues, we have been exploring single-die processing of underbump metals, interposers with solder and metal pillars for flip-chip integration, and other approaches targeting these technology sets. This presentation will start with an overview of Sandia, followed by a summary of Sandia's Microsystems capability and early-stage research activities in next-generation microsystem device technologies. Finally, the presentation will focus on RF miniaturization technology developments and a vision for an adaptable and scalable 2.5D approach for heterogeneous integration within practical limits of technology access, development costs, and turn-time.
