Modern life is increasingly dependent on advanced semiconductor devices, as they are used in smartphones, cars, and AI-based technologies. Advanced semiconductors are also becoming more critical to Japan's economic security. Semiconductor devices are mainly made from silicon, and miniaturization has been proceeding to realize faster operation speeds as well as to reduce their energy consumption. Recently, ultrathin sheets down to atomic thickness, called two-dimensional (2D) materials, have attracted great interest as new materials for future semiconductor devices. In this talk, after reviewing the current status of semiconductor devices, I introduce the state-of-the-art in 2D semiconductors with their synthesis methods and discuss the development of the science of 2.5D materials, made of multiple 2D materials.
