NEEI-6301 Integrated Circuit Devices (IC 520)

Course Description: This course will cover basic solid state physics concepts involving crystal structure, and the principles of quantum physics as it applies to semiconductor devices. It will cover the essentials of semiconductor physics including band diagrams, electrons and holes, density of states, Fermi statistics, carrier drift and diffusion. It will apply these concepts to pn junction diodes and metal-semiconductor junctions. This course will provide an overview of MOS and bipolar devices in terms of current-voltage and capacitance-voltage behavior, as well as scaling issues. We will cover basic circuit models and reliability physics. The course will also describe the operation and design issues of Si integrated circuits, point out applications and discuss some process integration, reliability and testing issues. It will also describe the operation and design issues of optoelectronic detectors and sources.
