Grand Finale Panel: Challenges for the Sustainable Development of Semiconductor Industry

Friday, December 18 | 1:00 pm - 2:00 pm
Semiconductors have continued to grow over the past half century, and today they are a fundamental technology for all human activities. The unrelenting innovation should be the reason it has not become a commodity and kept it at the forefront of technologies. On the other hand, the world surrounding the industry is becoming increasingly divided, confrontational, and disparate due to the various issues that have been brought to light and accelerated by COVID-19, and as a result, the world is moving in the direction of greater social and economic distortion. Also, the COVID-19 crisis and the giga fires in Australia and the U.S. have raised global environmental awareness to an unprecedented level, and the introduction of a Carbon Boarder Tax is being discussed, especially in Europe. With the introduction of EUV lithography and the significant increase in energy consumption during semiconductor manufacturing, the semiconductor industry is expected to have an active debate on how to allocate the carbon credit across the supply chain and customers. A panel composed of executives of Japan semiconductor supply chain and a supervising ministry will discuss sustainable developments and innovations of our industry. Panelists are Hirohide Hirai, Deputy Director-General, Commerce and Information Policy Bureau, Ministry of International Trade and Industry, Atsuyoshi Koike, president of Western Digital Japan, Tetsuo Tsuneishi, chairman of Tokyo Electron and Mitsunobu Koshiba, chairman of JSR. ★This session will be delivered on demand from December 21th to January 15th, 2021.
