講義概要

This class provides the fundamentals of advanced nanoscale MOS transistors. Firstly, the operation of MOS transistors on bulk Si substrate will be explained. The impact of shrinking device dimensions on device performance will be discussed. Then, the concept of equivalent scaling, which is important in modern MOS transistors, will be introduced. As an example of the equivalent scaling, mobility booster technologies and high-k and metal gate stack will be shown.

講義の目的

The objectives of this class are 1) to understand the operation principle of MOS Transistors and 2) to know how to desing MOSFETs to achieve higher performance. Advanced technologies such as stress engineering, high-k gate dielectrics, metal gate electrode, and new channel materials will be introduced. For each technology, not only advantages but also technical issues which should be overcome will be addressed. By taking this class, students are expected to get familiar with technologies of modern, advanced CMOS devices and physics behind nanoscaled transistors.
