Abstract:
Methods and apparatuses for selectively growing metal-containing hard masks are provided herein. Methods include providing a substrate having a pattern of spaced apart features, each feature having a top horizontal surface, filling spaces between the spaced apart features with carbon-containing material to form a planar surface having the top horizontal surfaces of the features and carbon-containing material, selectively depositing a metal-containing hard mask on the top horizontal surfaces of the features relative to the carbon-containing material, and selectively removing the carbon-containing material relative to the metal-containing hard mask and features.
