Over the last three decades we have witnessed the market acceptance of Si-based Power MOSFETs and IGBTs in power systems. Growth in demand was driven by the need to improve the energy efficiency of these systems, by the need to generate energy from renewable resources and by the development of better medical devices.
The performance envelopes for these new devices required new methods of assembly, new packages and integration that will add value and allow the full benefits of the new 'power chips' to be used by design engineers. The requirements included higher switching frequency operation, high thermal conductivity, high temperature and high voltage stability, electrical isolation and system integration at the device level. In this talk we summarize innovative assembly and packaging solutions that meet these requirements with cost reduction, size and weight reduction and suitability for automated production lines.
The key feature of the described technology is the use of DCB and DAB as the core substrate instead of the classical all-copper lead frame or baseplate.
- Speaker Biography:
Dr. Nathan Zommer founded IXYS in 1983, and has been Chairman and Chief Executive Officer since 1993.
He guided IXYS' development of its HiperFETTM technology, a key milestone in developing the legendary GM EV1 electric in 1989 and, later, the rugged IGBTs that assisted the development of the Tesla Roadster.
As the first fabless power semiconductor company, IXYS was conceived with the objective of bringing robust, high-current power MOSFETs, IGBTs, and control ICs to the market to facilitate the creation of higher-efficiency, high-frequency power systems.
Dr. Zommer started his career at HP Labs in Palo Alto. Following that he worked at Intersil-GE, where he was responsible for the development of the first commercial IGBT. He published the first technical paper about IGBT technology at the International Electronic Devices Meeting in 1982.
Since the earliest days of IXYS, Dr. Zommer has been an advocate of energy-efficient technologies as strategic investment opportunities. His focus has been on improved power conversion efficiency, leading to reduced monetary and environmental costs. He holds more than 75 patents, has authored numerous technical papers and articles in the field, and has been an advisor to numerous startups worldwide.
Dr Zommer received the PhD in Electrical Engineering from Carnegie Mellon University, with a research emphasis in power transistors.
