Method and apparatus for decreasing deposition time of a thin film

摘要

A method and apparatus for decreasing deposition time of a thin film are disclosed. The apparatus includes a removable shield assembly disposed in a vacuum chamber. The shield assembly forms an enclosure to house a substrate during an ALD process. A gas line coupled to the shield assembly introduces a gas into the enclosure to form a thin film on a surface of the substrate. A final valve is associated with the gas line and located proximate the shield assembly such that placement of the final valve with respect to the shield assembly provides fast delivery of the gas into the enclosure.
