Yutaka Ohno of Nagoya University and his research team members developed a transparent semiconductor integrated circuit that transmits more than 90% of light. They employed carbon nanotube for transistors and wiring. It will be possible to build frameless electronic paper should the transparent semiconductor be put on a transparent display. The new product is the result of the joint research with Aalto University of Finland.
They built a logic circuit for computing, an oscillation circuit that divides signal transmission time, and a data storage circuit on trial. Each of the three components is about 0.5 mm square, and it is possible to build a micro processing unit by combining these three components. The research team used vacuum equipment for part of the production process. In the future, it plans to perform the whole production process in the atmosphere with the help of an ink-jet printer.
