The fabrication of MOS transistors involves several key steps:
As we look ahead to the challenges of the 3nm node and beyond, the core lessons of Nicollian and Brews—the critical importance of interfaces, the profound effects of electric fields, and the delicate dance between physics and technology—are more relevant than ever. They provide the foundational knowledge needed to engineer the next generation of electronic devices that will, once again, reshape our world.
In an era of automated simulation tools like TCAD (Technology Computer-Aided Design), engineers still return to classic texts. Why? Because automated tools are only as good as the physics programmed into them.
When a voltage ( V_G ) is applied to the metal gate relative to the semiconductor, the semiconductor surface enters one of three regimes: The fabrication of MOS transistors involves several key
Modern high-k metal gate (HKMG) processing introduces significant interface and bulk oxide trapping phenomena. Engineers use the exact frequency-dependent conductance and capacitance-voltage (C-V) profiling methods pioneered by Nicollian and Brews to characterize and minimize these defects.
dielectrics and multi-gate field-effect transistors (FinFETs/GAA), the mathematical models, admittance techniques, and instrumentation theories detailed by Nicollian and Brews remain essential for contemporary semiconductor device testing, characterization, and reliability physics. The Crucial Role of the MOS Architecture
The simplest MOS device is a capacitor. By applying a voltage to the metal gate, one can control the charge distribution in the underlying semiconductor. As the gate voltage is varied, the semiconductor surface can be driven into three distinct regimes: Nicollian and John R. Brews

Even though it was published in 1982, this text remains the standard reference for engineers and physicists working in semiconductor device manufacturing. It is famous for its rigorous mathematical treatment of the MOS capacitor and the detailed explanation of measurement techniques (C-V and I-V curves). It bridges the gap between theoretical solid-state physics and practical device engineering.
