A method for forming films on particles of powder includes diffusing the powder by leading the powder into a jet nozzle and ejecting a jet flow of the powder; leading the diffused particles of powder, a raw material gas, and a reaction gas activated by atmospheric pressure plasma, into a reaction container, and forming a swirl flow in the container; and forming the films on the diffused particles of powder by reaction of a raw material gas and an activated reaction gas in the container. An apparatus is also disclosed having a reaction container with a peripheral wall having a round section in plan view and a jet nozzle for a powder source, raw material gas, and atmospheric pressure plasma sources are coupled to and enter the container at an angle with a radius thereof thereby forming a swirl flow to form a film on the powder.

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.
