Course description
Electronic devices are used in a wide range of fields, from information equipment such as PCs and cell phones to home appliances, railroads, automobiles, and industrial equipment, and are indispensable to today's society. Electronic devices include a wide variety of products ranging from individual semiconductors such as diodes and transistors to LSIs, power devices, image sensors, and MEMS (Micro Electro Mechanical Systems). In this lecture, the physics of semiconductors, which are the basis of these products, and the basic structure and operation of diodes, bipolar transistors, and MOSFETs, which are elemental devices, will be explained. The lecture will also provide examples of actual products, explain the functions of electronic devices in those products, and deepen students' understanding of electronic device applications.
Purpose of class
In understanding natural science, it is extremely important to use simple models that can be explained to people without specialized knowledge. In this lecture, students will understand band theory, density of carriers such as electrons and holes, and electrical conduction in order to understand the behavior of electrons based on silicon crystals, the most commonly used material in electronic devices. Based on this, students will be able to explain the basic operation of diodes, bipolar transistors, and MOSFETs, which are elemental devices, using energy band diagrams. Furthermore, students should be able to outline the functions of actual electronic device products such as sensors, LSIs, and power devices.
Goals and objectives
  1. to explain the relationship among conductivity type, carrier density, resistivity and doping density of the semiconductor
  2. to explain the characteristics of pn junction using energy band diagram
  3. to understand the operation principle of bipolar transistor and explain the variety of bipolar transistors in connection with their device structure and electric characteristics
  4. to understand the operation principle of MOSFET and explain the variety of MOSFET's in connection with their device structure and electric characteristics
  5. to explain the basic function and role of various products od electron device
