강의계획서

This class is an introduction to the physical principles of semiconductor devices and their fabrication technology. It is intended to incorporate the basics of semiconductor materials and conduction processes in solids, which arise repeatedly in the class when new devices are explained. One of the keys to success in understanding the semiconductor physics is to work problems that exercise the concepts. Therefore, three or four problems at the end of each chapter are assigned to the homework every week. In addition, we apply the knowledge learned in class directly to electronic devices such as pn junction and light-emitting diodes, through AMPS-1D Simulation. The class includes both silicon and compound semiconductors, to reflect the continuing growth in importance for compounds in optoelectronic and high-speed device applications.

차시별 강의

1.	Semiconductors: A general introduction	We begin the discussion by examining the general nature of semiconducting materials.
2.	Crystal structure	We examine how one goes about describing the spatial positioning of atoms within crystals.
3.	Semiconductor Models	We introduce and describe two very important models or visualization aids that are used extensively in the analysis of semiconductor devices.
4.	Equilibrium carrier concentrations	We develop to lead the relationships for the carrier distributions and concentrations within semiconductors under equilibrium conditions.
5.	Drift and diffusion	We describe each primary type of carrier action qualitatively and then quantitatively relate the action to the current flowing within the semiconductor.
6.	Recombination-generation	We focus on the recombination-generation which is a nature’s order-restoring mechanism, the means whereby the carrier excess or deficit inside the semiconductor is stabilized or eliminated.
7.	Fabrication processes	The fabrication processes constitute the final preparatory step before the consideration and analysis of specific devices. The goal is to develop a general feel for the physical nature of device structures.
8.	Introduction to pn junction	We examine devices whose operation is intimately tied to the one or more pn junctions built in the structure.
9.	pn junction electrostatics	We develop quantitative relationships for the electrostatic variables in the pn junction.
10.	Ideal diode equation	We work to modeling the steady state response of the pn junction diode.
11.	Reverse-bias breakdown	We compare experiment and theory to identify the major deviations from the ideal diode.
12.	pn junction diode: Capacitance	We examine and model the small signal response of the pn junction diode.
13.	Optics and photodiodes	We consider special diode structures that are specifically designed and built for optical applications.
14.	Solar cells	We study two groups of photodevices converting photo-energy into electrical energy. One is a photodetector, and the other is a solar cell. Especially, we use AMPS-1D, a solar cell simulation program, to understand solar cells.
