However, as devices scaled below 45 nm, SiO₂ thickness reduced to <2 nm, leading to excessive gate leakage due to direct tunneling. This forced the industry to adopt high-κ dielectrics.

Nicollian and Brews delve into specific phenomena that define modern semiconductor device behavior: as devices scaled below 45 nm
When a voltage ( V_G ) is applied to the metal gate relative to the semiconductor, the semiconductor surface enters one of three regimes: SiO₂ thickness reduced to <
