1. An ampoule for a semiconductor manufacturing precursor, the ampoule comprising:
a container defining a cavity configured to hold the precursor;
an inlet port and an outlet port, both in fluid communication with the cavity;
an inlet plenum located between the inlet port and the cavity;
an outlet plenum located between the outlet port and the cavity, wherein the outlet plenum is closer to a radial center of the container than the inlet plenum;
a plurality of elongate walls containing the precursor arranged to define flow channels including an outermost channel and an innermost channel, each of the elongate walls comprising an ingress opening; and
a flow path defined by the inlet port, the flow channels, the ingress openings, and the outlet port through which a carrier gas flows in contact with the precursor, the flow path configured to flow from the outermost channel to the innermost channel to the outlet port.
