Course description and aims

This course focuses on the device characteristics of electron devices (semiconductor devices) used in integrated circuits such as pn diodes, MOS diodes, bipolar transistors, and MOS transistors. The device structures and basic characteristics are explained for two-terminal devices such as pn diodes and MOS diodes, and three-terminal devices such as bipolar transistors and MOS transistors. The importance of 3-terminal devices in integrated circuits is discussed, which enables students to learn how the devices are applied in integrated circuits. Furthermore, the instructor explains the basic characteristics of the complementary MOS transistors (CMOS) used as a basic gate in the integrated circuits, and power devices used for power conversion devices. Through lectures and exercises, students deepen their understanding of the operating characteristics of electron devices.
The integrated circuits used in electronics for information and communication technology are created by integrating a huge amount of electron devices such as diodes and transistors. In order to achieve high performance of integrated circuits, it is necessary to improve the characteristics of electron devices with an understanding of the device physics. Through this course, students learn how precisely controlling the behavior of electrons and holes in a semiconductor allows for creating the operating characteristics of electron devices.

Student learning outcomes

By the end of this course, students will be able to:
1) Explain the amplification of transistor.
2) Expand the band diagram of pn diode to explain the rectifying characteristic in current-voltage characteristic.
3) Explain the basic characteristics and design of high-speed bipolar transistor.
4) Expand the inversion characteristic of MOS diode to explain the basic characteristics and design of scaled MOS transistor.
5) Explain the structure and characteristics of CMOS consisting of p-channel MOS transistor and n-channel MOS transistor.
6) Explain the structure and characteristics of power devices.

Class flow

At the beginning of each class, solutions to exercise problems that were assigned during the previous class are reviewed. Towards the end of class, students are given exercise problems related to the lecture given that day to solve. To prepare for class, students should read the course schedule section and check what topics will be covered. Required learning should be completed outside of the classroom for preparation and review purposes.
