Some issues in advanced CMOS gate stack performance and reliability
2011
This paper summarizes and analyzes some of our previous works on the advanced gate stacks for CMOS transistors focused on the following two topics: 1. Frequency dependence of Dynamic Bias Temperature Instability (DBTI) and the transistor degradation mechanism, 2. A novel way for metal gate Effective Work Function (EWF) modulation by incorporation of lanthanum elements in HfO"2 gate dielectric.
