Reliability studies of a 32nm System-on-Chip (SoC) platform technology with 2nd generation high-k/metal gate transistors

Extensive reliability characterization of a state of the art 32nm strained HK/MG SoC technology with triple transistor architecture is presented here. BTI, HCI and TDDB degradation modes on the Logic and I/O (1.2V, 1.8V and 3.3V tolerant) transistors are studied and excellent reliability is demonstrated. Importance of process optimizations to integrate robust I/O transistors without degrading performance and reliability of Logic transistors emphasized. Finally, Intrinsic and defect reliability monitoring for HVM are addressed.
