Abstract:
The present invention provides for a method of fabricating a semiconductor device, the method includes depositing a nitride layer on an ETSOI layer; forming a dummy gate over the nitride layer; forming nitride gate spacers from the nitride layer; growing a sacrificial layer on the ETSOI layer, the sacrificial layer composing a material that can be at least partially converted to a metal layer by a metal-bearing gas; forming refractory metal contacts using the sacrificial layer and a consumptive process; depositing an oxide protect layer on the refractory metal contacts; removing the dummy gate using a mask and etch process combined with chemical-mechanical polishing (CMP); etching the ETSOI layer to form a U-shaped channel; and depositing the final gate stack into the U-shaped channel.

Claim (Index 7):
The method of  claim 1 , wherein the sacrificial layer is fully converted to a metal layer by a metal-bearing gas.
