Claim 10:
11. A semiconductor processing system, comprising:
a gas splitter defining a plurality of gas inlets and a plurality of gas outlets, wherein a number of the plurality of gas outlets is greater than a number of the plurality of gas inlets;
a plurality of valve blocks that are each interfaced with the gas splitter, wherein:
each of the plurality of valve blocks defines a number of gas lumens;
an inlet of each of the gas lumens is in fluid communication with one of the plurality of gas outlets; and
an interface between the gas splitter and each of the plurality of valve blocks comprises a choke having a diameter that is less than a diameter of each of the plurality of gas outlets and of each of the inlets of the gas lumens; and

a plurality of output weldments, each output weldment of the plurality of output weldments fluidly coupling an outlet of one of the gas lumens with one of a plurality of output manifolds.
