Abstract:
A FinFET device and a method of forming the same are provided. A method includes forming a fin extending above an isolation region. A sacrificial gate is formed over the fin. A first dielectric material is selectively deposited on sidewalls of the sacrificial gate to form spacers on the sidewalls of the sacrificial gate. The fin is patterned using the sacrificial gate and the spacers as a combined mask to form a recess in the fin. An epitaxial source/drain region is formed in the recess.

Claim (Index 15):
A method comprising:\n etching an isolation region to expose sidewalls of a semiconductor fin; forming a first oxide material on the sidewall and a top surface of the semiconductor fin; forming a conductive material over the first oxide material; forming a second oxide material over the conductive material; etching the second oxide material to form a patterned second oxide material; etching the conductive material using the patterned second oxide material as a mask to form a sacrificial gate over the semiconductor fin; forming a first dielectric material on sidewalls and a top surface of the patterned second oxide material, and over exposed portions of the first oxide material; performing a fluorination process on the patterned second oxide material and the exposed portions of the first oxide material, the fluorination process forming a fluorinated patterned second oxide material; removing the first dielectric material; selectively depositing a second dielectric material on sidewalls of the sacrificial gate; etching the semiconductor fin using the fluorinated patterned second oxide material, the sacrificial gate and the second dielectric material as a combined mask to form a recess in the semiconductor fin; and epitaxially growing a semiconductor material in the recess.
