Professor Takaaki Suzuki is engaged in the design, analysis, and development of ultra-fine processing technology and its systems in units of micrometers and nanometers. The original processing technology he developed is called "Three-dimensional (3D) lithography," announced in 2006. It is an innovative photolithography method (light shaping) where the inclined substrate is rotated during exposure. Previously, there was no technology capable of processing the intermediate size between "small machinery/precision products" found in smartphones and the nanoscale precision of semiconductors, which roughly falls from a few micrometers to sub-millimeters. The 3D lithography method is the method aiming to fill this gap. He has received the Minister of Education, Culture, Sports, Science and Technology Award and obtained patents in Japan and the United States. 3D lithography has evolved into an innovative technology capable of processing three-dimensional microstructures previously unachievable with existing techniques. It is now applied in high-performance biotechnology, optics, and IoT (Internet of Things), advancing innovation in Japan's manufacturing sector.
