摘要： A method is provided for manufacturing an inkjet nozzle. The method includes the step of depositing a plastics material layer on a substrate incorporating heater actuator circuitry. The plastics material layer is etched to form a nozzle rim defining an ink port through which ink can be ejected and a plurality of elongate actuator arms extending radially with respect to the nozzle rim. A tapered ink chamber may be etched in the nozzle body so that the ink port and ink chamber are in fluid communication with each other.

摘要： A method of fabricating a printhead integrated circuit includes the step of forming a first layer of a polymeric material on a substrate that incorporates drive circuitry. A heater element is formed on the first layer of polymeric material to be connected to the drive circuitry. A second layer of a polymeric material is formed on the heater element and the first layer such that the heater element is embedded in polymeric material. The polymeric layers are etched to define a plurality of radially extending bridging portions which terminate in a nozzle rim and a plurality of actuators which each extend between a respective pair of adjacent bridging portions and each terminate in a free end proximal to the rim. The substrate is etched so that the substrate and the actuators define a nozzle chamber in fluid communication with an ink ejection port defined by the nozzle rim.
