Abstract:
Stress is introduced into the channel of an SOI FinFET device by transfer directly from a metal gate. In SOI devices in particular, stress transfer efficiency from the metal gate to the channel is nearly 100%. Either tensile or compressive stress can be applied to the fin channel by choosing different materials to be used in the gate stack as the bulk gate material, a gate liner, or a work function material, or by varying processing parameters during deposition of the gate or work function materials. P-gates and N-gates are therefore formed separately. Gate materials suitable for use as stressors include tungsten (W) for NFETs and titanium nitride (TiN) for PFETs. An optical planarization material assists in patterning the stress-inducing metal gates. A simplified process flow is disclosed in which isolation regions are formed without need for a separate mask layer, and gate sidewall spacers are not used.

Claim (Index 19):
The method of  claim 16 , further including forming a first mask on the second gate dielectric.
