Abstract
A nozzle assembly for an inkjet printhead is disclosed. The nozzle assembly includes an inkjet nozzle having an actuator for ejecting an ink droplet from the inkjet nozzle when a resistive element of the actuator is heated by an electrical current. A drive transistor provides an energy pulse to the resistive element of the actuator, and control logic controls the drive transistor. The drive transistor and control logic are formed on a silicon substrate, and the inkjet nozzle is formed over the drive transistor and control logic.
