- Abstract
- The effect of the surface roughness of strained Si grown on relaxed SiGe-on-insulator on the electrical characteristics of n-MOSFETs was investigated. The surface roughness-induced degradations of the driving current and leakage current were minimized by applying, after conventional rapid thermal annealing (RTA), an additional furnace annealing consisting of 30 min in a N-2 ambient at 500 degrees C. The improvements resulted from the post-RTA process decreasing the charge density of the interface state.
