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 16):
A method of fabricating a semiconductor device comprising:\n depositing an ETSOI 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 a source region and a drain region from the sacrificial layer; forming a refractory metal layer using the sacrificial layer and a consumptive process; depositing a thick oxide hard mask layer on top of the ETSOI layer; forming a dummy gate on the top of the ETSOI layer; depositing a nitride layer over the source region and the drain region to form gate spacers; depositing an oxide protect layer on the refractory metal contacts and using chemical-mechanical polishing (CMP) to expose the dummy gate; removing the dummy gate and leaving a cavity; and removing the oxide protect layer and dummy gate dielectric layer to expose the source region and the drain region contacts.
