  • Publication number: 20220411924
    Abstract: Ampoules for a semiconductor manufacturing precursors and methods of use are described. The ampoules include a container with an inlet port and an outlet port. Alternating first and second elongate walls in the container are arranged to define longitudinal flow channels containing a precursor material, and alternating first and second passages between each of the longitudinal flow channels permitting fluid communication between adjacent longitudinal flow channels, wherein the first passages are located in a lower portion of the precursor cavity and the second passages are located an upper portion of the cavity. A flow path is defined by the longitudinal flow channels and the passages, through which a carrier gas flows in contact with the precursor material. In one or more embodiments, the precursor material is a solid.
