WebFig. 5. The resulting metal gate/high-K dielectric stacks have equivalent oxide thickness (EOT) of 1.0nm with negligible gate oxide leakage, and channel mobilities that are close to SiO2 (Figs. 6-7). 80nm physical-gate-length CMOS transistors with the new metal gate/high-K dielectric stacks have been fabricated to produce the WebThe residual stress can be controlled to slightly tensile by changing the annealing temperature. High tensile stress was observed during the annealing of high-frequency plasma-deposited films, leading to film cracks that limit the film thickness, as predicted by the strain energy release rate equation. Thick films without cracks were obtained
