Abstract

Official abstract text for this publication.

A point-of-use valve (POU valve) manifold is provided that allows for multiple precursors to be delivered to a semiconductor processing chamber through a common outlet. The manifold may have a plurality of precursor inlets and a purge gas inlet. The manifold may be configured such that there are zero dead legs in the manifold when the purge gas is routed through the manifold, and may provide mounting location for the POU valves that alternate sides. One or more internal flow path volumes may include elbow features.

First claim

Opening claim text (preview).

What is claimed is: 1. A valve manifold for use in a semiconductor processing tool, comprising: a manifold body; a purge gas inlet; a manifold outlet, the manifold outlet located on a first side of the manifold body; a first valve interface, the first valve interface located on a second side of the manifold body different from the first side; and a second valve interface, the second valve interface located on a third side of the manifold body different from the first side…
