Abstract
A method of fabricating a semiconductor device is disclosed. A substrate is provided. A dummy gate stack is formed on the substrate. The dummy gate stack includes a gate dielectric layer and an amorphous silicon dummy gate on the gate dielectric layer. The amorphous silicon dummy gate is transformed into a nano-crystalline silicon dummy gate. A spacer is formed on a sidewall of the nano-crystalline silicon dummy gate. A source/drain region is formed in the substrate on either side of the dummy gate stack.
