Awards

SSDM Award

The SSDM Award is awarded to researchers who contributed an outstanding paper at the past SSDM conferences.

The Insulated Gate Bipolar Transistor (IGBT) is currently the leading power semiconductor device. During initial development, however, the IGBT had an intrinsic problem. Latch‐up phenomena, which were caused by the thyristor structure inherent in the device, narrowly limited the Safe Operating Area (SOA) for voltage and current. This paper proposed and demonstrated the first tangible solution in the world to this problem. The concept became the theoretical guideline for designing IGBTs commercialized in countries around the world. It can be said that this paper was the starting point for such practical implementation.

Around 1980, research was actively being pursued on the MOS‐controlled thyristor which an MOS gate turns on and off, to be the power semiconductor that would globally succeed the high‐voltage bipolar transistor. Among those efforts, the discovery that a horizontal MOS thyristor could operate the transistor (1978) prompted greater interest in development of a device structure that would realize the operation. However, these attempts were unable to solve the problem of the thyristor easily latching up on account of the PNPN structure with its alternating P‐type and N‐type layer arrangement, which was essentially inherent in the device structure. As such, no practically applicable device ever resulted. Amid the focus of much research on the flow of electrons, this paper showed that it was possible to formulate conditions triggering latch‐up by focusing on the hole current supplied by P‐type layer on the back surface of the chip and that, based on this, a design which would prevent latch‐up could be worked out. The outcome of this paper was that the SOA of the IGBT expanded significantly up to a practical level, opening the way for commercialization as well as developing rapidly on high power IGBTs for industrial motors and other applications.

Currently, the IGBT has been developed to handle even higher current densities (for home appliances) and its high performance has been realized at overwhelmingly low cost. This has made it a core device in fields applying power semiconductors. It has also been projected the IGBT will be a key device in CO2 reduction and renewable energy adoption. The IGBT market continues to grow 10% annually and could conceivably reach 1 trillion yen.

As explained above, the results of the research published in this paper have made a substantial contribution from a fundamental perspective to the development of industrial applications for the IGBT, the most important power device of our day, and the paper's great contribution has also been acknowledged from the standpoint of constructing device design guidelines that fully utilize numerical simulations. Therefore, the SSDM Award is presented to the authors of this paper in recognition of their achievements.

  For the further spread of electric vehicles, it is essential to improve the performance of batteries. High‐rate charging is a particularly challenging issue. I believe that the results presented here will provide clues to solving this issue. I currently investigate the effects of carbon anode and solid electrolyte factors on charging and discharging, respectively.
