The widespread adoption of chat-type AI has made it possible for anyone to easily generate texts, images, and music. As AI continues to advance, it is increasingly taking over many intellectual tasks traditionally performed by humans. This remarkable progress in AI has been significantly enabled by the advancements in nano CMOS VLSI technology.

In this talk, I will begin by exploring the role of ICT technology in human society and the contributions of CMOS technology to the field. I will then outline the evolution of transistor and CMOS technologies from their inception to the present day. Finally, I will discuss the potential limits of device miniaturization and future directions, including 3D integration and the integration of biotechnology.
