Abstract (en)
A printhead integrated circuit comprises a substrate (1) having a plurality of inkjet nozzles assemblies (100) formed on a surface of the substrate. The substrate has drive circuitry for supplying power to the nozzle assemblies. Each nozzle assembly comprises: nozzle chamber (5) for containing ink, the nozzle chamber having a nozzle opening defined therein (13) and a wall of insulating material (4) defining a sidewall of the nozzle chamber; an actuator (10) for ejecting ink through the nozzle opening; a pair of electrodes (2) positioned at the surface of the substrate; and a pair of connector posts (8) electrically connecting a respective eledrode (2) to the actuator (10). Each connector post extends linearly from a respective electrode (2) to the actuator (10), and each connector post fills a via defined in the sidewall (4) of the nozzle chamber (5).
