Abstract

Exemplary substrate processing system faceplates may include a plate that is characterized by a first surface and a second surface opposite the first surface. The second surface may define a plurality of recesses that extend through a portion of a thickness of the plate. The plate may define a plurality of apertures through the thickness of the plate. Each aperture may extend through a bottom surface of one recess of the plurality of recesses. Each recess may have a greater diameter than the aperture extending through the bottom surface of the recess. The faceplate may include a plurality of shape-memory actuators. Each shape-memory actuator may be seated within a respective one of the plurality of recesses. Each shape-memory actuator may define an actuator aperture. A diameter of the actuator aperture each shape memory actuator may be variable.
