ABSTRACT:
A micro-electromechanical fluid ejection device includes a substrate that defines a fluid inlet channel and incorporates a wafer and drive circuitry positioned on the wafer. Nozzle chamber walls extend from the substrate and bound the fluid inlet channel to define a nozzle chamber in fluid communication with the fluid inlet channel and a fluid ejection port. An elongate actuator is connected at one end to the drive circuitry. An opposite end of the actuator is displaceable towards and away from the substrate on receipt of an electrical signal from the drive circuitry. The actuator includes an interconnect portion that defines a transversely extending face and is received through a complementary opening defined in the walls and a fluid ejection member that is fast with said face. The interconnect portion and said opening are shaped so that movement of the fluid ejection member is controlled.
