| 20080217700 | Mobility Enhanced FET Devices - NFET and PFET devices with separately stressed channel regions, and methods of their fabrication is disclosed. A FET is disclosed which includes a gate, which gate includes a metal in a first state of stress. The FET also includes a channel region hosted in a single crystal Si based material, which channel region is overlaid by the gate and is in a second state of stress. The second state of stress of the channel region is of an opposite sign than the first state of stress of the metal included in the gate. The NFET channel is usually in a tensile state of stress, while the PFET channel is usually in a compressive state of stress. The methods of fabrication include the deposition of metal layers by physical vapor deposition (PVD), in such manner that the layers are in stressed states. | 09-11-2008 |
