Negative bias temperature instability (NBTI) is a degradation mechanism in p-channel metal-oxide-semiconductor field-effect transistors (MOSFETs) that leads to a threshold voltage increase and a decrease in drive current. It occurs when a negative bias is applied to the gate of a p-channel MOSFET at elevated temperatures, causing the breaking of Si-H bonds at the Si/SiO2 interface and the creation of interface traps, which capture holes and increase the threshold voltage. NBTI can significantly impact the performance and reliability of integrated circuits, leading to device failures and reduced circuit lifetime. Mitigation techniques include substrate bias optimization, high-κ dielectrics, and stress annealing.
