The Capacitance-Voltage (C-V) curve of an MOS capacitor is a powerful diagnostic tool. By measuring how the capacitance changes with gate voltage, engineers can extract critical information about the semiconductor's doping concentration, the thickness of the oxide, and most importantly, the density of defects and charges at the Si-SiO₂ interface.
: Occurs when the applied gate voltage attracts majority carriers to the semiconductor-oxide interface.
The field of MOS physics and technology stands as one of the towering achievements of applied science. It has transformed the world, enabling the digital age from personal computers to smartphones to artificial intelligence. The iconic text by E.H. Nicollian and J.R. Brews, MOS (Metal Oxide Semiconductor) Physics and Technology , remains the definitive guide to the fundamentals of this field, a tribute to the rigorous scientific and engineering work that made the revolution possible. The Capacitance-Voltage (C-V) curve of an MOS capacitor
Starting at the 45 nm node (Intel, 2007), HfO₂ (κ ~25) replaced SiO₂ (κ ~3.9). To avoid phonon scattering and Fermi level pinning, metal gates replaced polysilicon. HKMG enables thicker physical oxide while maintaining equivalent electrical thickness (EOT), drastically reducing leakage.
You might wonder why a text from 1982 is still a "hot" search term in the 2020s. The reason is simple: physics doesn't change. The field of MOS physics and technology stands
