Semiconductor engineering is one of the most important subjects in material science because various semiconductor devises are extensively used in electric appliances and essential to electric appliances. The purpose of this lecture is to introduce fundamental and application of electronic property of semiconductor from viewpoint of material science. This lecture starts from description of energy and density of electrons in solid and follow description of electric conduction mechanism in solid, pn junction, and metal-semiconductor contact. The letter half of the lecture is for fabrication process and application of representative semiconductor materials. The devices using pn junction such as diode, transistor will be also explained.
The purpose of this lecture is to understand basic theory of electric property of solid and its mechanism of electric conduction in solid as well as to become proficient at semiconductor materials and its application to electronic devices. Furthermore, this lecture aims to learn and acquire skills or knowledge to design functional semiconductor materials and develop new electronic devices.
