Abstract:
A method for forming a FinFET device is described. The method includes the following steps. A substrate is patterned to form fins. Dummy gate stack is formed on the substrate and over the fins, wherein the dummy gate stack may be formed by the following steps: a dummy layer is formed; a first etching step is performed on the dummy layer with a bromine containing etching gas to form a dummy strip; a second etching step is performed on the dummy strip with a chlorine containing etching gas to form the dummy gate stack. The dummy gate stack is replaced with a gate stack.

Claim (Index 11):
The method for forming the FinFET device according to  claim 10 , wherein the source power of the second etching step is in the range of 1000 W to 1500 W.
