PRINTHEAD AND RELATED METHODS AND SYSTEMS |
摘要 |
<p>A printhead includes a moveable membrane, a piezoelectric actuator to move the membrane, and electronic circuitry disposed on the moveable membrane. A method of fabricating a printhead includes fabricating CMOS circuitry on a first side of a circuit wafer, and forming a chamber in a second side of the circuit wafer such that a bottom of the chamber forms a moveable membrane and the CMOS circuitry is disposed on the moveable membrane opposite the bottom of the chamber. A printing system includes a printhead having CMOS circuitry formed on a first side of a moveable membrane, a chamber having a bottom comprising a second side of the moveable membrane, and a piezoelectric actuator formed over the CMOS circuitry, configured to cause displacement of the moveable membrane into the chamber.</p> |
