Abstract: We examine the technology options for the enhancement of electron mobility in n-channel metal-oxide-semiconductor field-effect transistors, focusing on channel strain engineering using lattice-mismatched source/drain (S/D) materials. Silicon-carbon (Si1-yCy) S/D induces lateral tensile strain in the Si channel for electron mobility and drive current improvement. This has been demonstrated on bulk planar transistors, silicon-on-insulator transistors, and multiple-gate transistors. Further performance enhancement is achieved by the combination of multiple-stressors, e.g. Si1-yCy S/D and silicon nitride liner stressor. Process integration issues and strain enhancement approaches are discussed. copyright The Electrochemical Society.
