1. A point-of-use (POU)-valve manifold to control admission of a plurality of gases into a tool, the POU-valve manifold comprising:
a manifold body configured to couple to a chamber of the tool; and
for each of the plurality of gases, the POU-valve manifold further includes:
a gas valve coupled to the manifold body and configured to be coupled to a gas supply, the gas valve having a separate gas flow path internal to and separated from remaining ones of the gas flow paths within the manifold body with the gases only able to meet at a common outlet of the POU-valve manifold to prevent any of the plurality of gases to be mixed within flow paths of the POU-valve manifold; and
an annulus to at least partially surround the common outlet of the POU-valve manifold.
