MOS Device Physics and Transistor Fundamentals

Modern electronics rely entirely on the precise control of electrical current through silicon. To design, analyze, or work with integrated circuits, you must first comprehend the underlying physical principles governing semiconductor behavior. This text-based course guides you from the absolute basics of silicon structures to the operational mechanics of modern transistors. You will transition from a conceptual understanding of semiconductor physics to confidently analyzing device characteristics and anticipating the challenges of nanoscale scaling. What you'll learn: - Understand foundational semiconductor physics, charge carriers, and band diagrams. - Analyze the metal-oxide-semiconductor capacitor structure under accumulation, depletion, and inversion. - Evaluate the current-voltage characteristics of standard MOSFET devices. - Identify short-channel effects and modern mitigation strategies like FinFET and gate-all-around architectures. - Calculate key device parameters such as threshold voltage, subthreshold swing, and leakage currents. This course begins with essential terminology, material properties, and basic electrostatic principles. You will then progress through the step-by-step physics of MOS capacitors, transition into three-terminal transistor operations, and conclude with modern nanoscale device design challenges. This course is designed for beginners, engineering students, and professionals looking for a solid theoretical foundation in device physics, with no advanced prior semiconductor experience required.
