About

Fujio Terai is a pioneering figure in robotics and semiconductor manufacturing, whose work bridges industrial automation and advanced materials processing. His research centers on two key areas: robotic inspection systems for heavy machinery and plasma-based wafer fabrication technologies. Terai’s most notable contribution is the development of a pushing control mechanism for generator inspection robots, which enables safe navigation through the narrow gap between a rotor and stator. This innovation reduces inspection time and extends maintenance intervals, addressing critical safety and efficiency challenges in power generation. The work has garnered 4 citations, reflecting its niche but significant impact. In parallel, Terai designed a hydraulic-and-electric double-arm robot tailored for cell production lines, where it handles heavy materials with human-like dexterity—a breakthrough for high-mix, low-volume manufacturing. Earlier in his career, he advanced semiconductor processing by developing a microwave-excited plasma asher using slot antennas for 300-mm wafers, achieving an ashing rate of 4.5 μm/min with exceptional uniformity. This work, cited twice, contributed to scaling wafer fabrication technologies. Terai’s interdisciplinary achievements highlight his ability to solve complex engineering problems across robotics and microelectronics, making him a notable innovator in applied industrial research.
