In a metal gate replacement process, strain may be selectively induced in the channels of NMOS and PMOS transistors. For example, a material having a higher coefficient of thermal expansion than the substrate may be used to form the gate electrodes of PMOS transistors. A material with a lower coefficient of thermal expansion than that of the substrate may be used to form the gate electrodes of NMOS transistors.

A semiconductor device comprising a gate electrode formed on a gate dielectric layer formed on a semiconductor film. A pair of source/drain regions are formed adjacent the channel region on opposite sides of the gate electrode. The source and drain regions each comprise a semiconductor portion adjacent to and in contact with the semiconductor channel and a metal portion adjacent to and in contact with the semiconductor portion.

A method for fabricating double-gate and tri-gate transistors in the same process flow is described. In one embodiment, a sacrificial layer is formed over stacks that include semiconductor bodies and insulative members. The sacrificial layer is planarized prior to forming gate-defining members. After forming the gate-defining members, remaining insulative member portions are removed from above the semiconductor body of the tri-gate device but not the I-gate device. This facilitates the formation of metallization on three sides of the tri-gate device, and the formation of independent gates for the I-gate device.
