ABSTRACT:
An inkjet printhead is provided comprising an array of microelectromechanical ink ejection devices formed on a wafer substrate. Each ink ejection device comprises an ink chamber defined by walls projecting from the wafer substrate to support a roof having an ink ejection port defined therein, and an electrically activated arm projecting from the wafer substrate into the ink chamber with one or more heat sinks formed thereon. Activation of the arm causes it to be displaced relative to the wafer substrate thereby causing ejection of ink from the ink chamber through the ink ejection port.
