Comparison of Reaction-Diffusion and Atomistic Trap-Based BTI Models for Logi…

In deeply scaled CMOS technology, time-dependent degradation mechanisms (TDDMs), such as Bias Temperature Instability (BTI), have threatened the transistor performance, hence the overall circuit/system reliability. Two well-known attempts to model BTI mechanism are the reaction-diffusion (R-D) model and the Atomistic trap-based model. This paper presents a thorough comparative analysis of the …
