Unified self-heating effect model for advanced digital and analog technology and thermal-aware lifetime prediction methodology

Self-heating effect (SHE) has become a significant concern for device performance, variability and reliability co-optimization due to more confined layout geometry and lower-thermal-conductivity materials adopted in advanced transistor technology, which substantially impacts the integrated circuit (IC)'s design schemes. In this work, a new methodology for evaluation of SHE in both digital and analog circuits is demonstrated by using pulse-aware and existing sine-aware analytical models respectively. Correlating SHE to physics-based thermal-aware reliability models provides insights for design and sign-offs of advanced digital and analog ICs.
