  • Substantially planar fluid ejection actuators and methods related thereto
    Patent number: 7559630
    Abstract: Fluid ejection actuators, micro-fluid ejection heads, and methods relating thereto. One such fluid ejection actuator is provided by a conductive layer adjacent a substrate. The conductive layer has a substantially non-conductive portion. The substantially non-conductive portion includes a portion of the conductive layer which has been treated to have low conductivity properties. A resistive layer is adjacent the conductive layer. The substantially non-conductive portion of the conductive layer substantially defines the fluid ejection actuator.
