碩士 / 國立臺灣大學 / 電子工程學研究所 / 103 / Since Moore’s law was proposed in 1965, transistor numbers have been increased from thousands to billions on a single chip. While the size of the transistor is scaling, the operating frequency is also enhanced from MHz toward THz. To maintain the scaling path and benefit from both price and performance boosting, short channel effects (SCEs) must be solved in each generation. To suppress SCEs, except for improving gate oxides, it can be achieved by 3D structures, i....
