Strain enhanced DC-RF performance of 0.13 µm nMOSFETs on flexible plastic substrate
A 14.3% saturation current Id,sat improvement and 0.75 dB minimum noise figure (NFmin) at 10 GHz were measured by applying ∼0.7% tensile strain for 16 finger, 0.13 µm RF MOSFETs with thin-body (40 µm) substrate mounted on plastic. These excellent results for mechanical-strain on DC-RF MOSFETs are better than those of SiN-capped 90 nm strained-Si nMOSFETs and consistent with device simulations.
