SEL was established in 1980, aiming to contribute to the world’s progress by transmitting fruits of innovative research and development pertaining to forthcoming needs of society. SEL’s core philosophy is “progress based on creation” which is a teaching of Dr. Yogoro Kato, the mentor of Founder Yamazaki.
SEL performs R&D process including simulation, design, fabrication, reliability evaluation, analysis, and measurement, and patent acquisition and enforcement to be completed in-house. Furthermore, we believe that technologies can contribute to the industry development only when utilized by others. We strive to develop technologies for practical use.
