Abstract: A fluid ejector includes a fluid ejection module and an integrated circuit element. The fluid ejection module includes a substrate having a plurality of fluid paths, a plurality of actuators, and a plurality of conductive traces, each actuator configured to cause a fluid to be ejected from a nozzle of an associated fluid path. The integrated circuit element is mounted on the fluid ejection module and is electrically connected with the conductive traces of the fluid ejection module such that an electrical connection of the module enables a signal sent to the fluid ejection module to be transmitted to the integrated circuit element, processed on the integrated circuit element, and output to the fluid ejection module to drive the actuator.

Abstract: Processes for forming an actuator having a curved piezoelectric membrane are disclosed. The processes utilize a profile-transferring substrate having a curved surface surrounded by a planar surface to form the curved piezoelectric membrane. The piezoelectric material used for the piezoelectric actuator is deposited on at least the curved surface of the profile-transferring substrate before the profile-transferring substrate is removed from the underside of the curved piezoelectric membrane. The resulting curved piezoelectric membrane includes grain structures that are columnar and aligned, and all or substantially all of the columnar grains are locally perpendicular to the curved surface of the piezoelectric membrane.
