Apparatuses including a plate having a recess and a corresponding protrusion to define a chamber
An example provides an apparatus including a plate having a nozzle orifice, a flat portion, and a first surface having a recess forming a corresponding protrusion extending from a second surface, opposite first surface, of the plate. A substrate may be in spaced relation to the flat portion of the plate such that the protrusion extends toward the substrate and such that the flat portion and the substrate define, at least in part, a chamber.
