MOLYBDENUM DEPOSITION

Provided are methods of filling patterned features with molybdenum (Mo). The methods involve selective deposition of Mo films on bottom metal-containing surfaces of a feature including dielectric sidewalls. The selective growth of Mo on the bottom surface allows bottom-up growth and high quality, vo...

More Information
Summary:Provided are methods of filling patterned features with molybdenum (Mo). The methods involve selective deposition of Mo films on bottom metal-containing surfaces of a feature including dielectric sidewalls. The selective growth of Mo on the bottom surface allows bottom-up growth and high quality, void-free fill. Also provided are related apparatus.
