Claim 12:
13. A point-of-use (POU)-valve manifold to control gases, the POU-valve manifold comprising:
a plurality of gas inlets and a corresponding number of gas outlets with each corresponding pair of the gas inlets and the gas outlets being coupled to a gas flow path within the POU-valve manifold that is separate from other gas flow paths, each of the plurality of gas inlets coupled to the POU-valve manifold to be controlled separately by at least one gas valve; and
a common outlet for the gas outlets, the gases flowing within the gas flow paths being configured to meet only at the common outlet of the POU-valve manifold to eliminate the possibility for any gases to be mixed within flow paths within the POU-valve manifold; and
an annulus to at least partially surround the common outlet for the gas outlets.
