Ink jet printhead chip with predetermined micro-electromechanical systems height |
摘要 |
The current invention provides for a nozzle arrangement for an inkjet printer. The nozzle arrangement includes a wafer substrate defining an ink supply channel therethrough, with side wall portions and a top wall portion arranged on the wafer substrate to define a nozzle chamber for operatively receiving ink, said top wall portion defining an ink ejection port and a plurality of etchant holes therein of sufficient diameter such that surface tension effects restrict ink being ejected from the chamber via the etchant holes. The nozzle arrangement also includes a thermal actuator cantilevered on the wafer substrate so that the actuator partitions the nozzle chamber, the actuator having a heater layer which produces thermal expansion of said actuator upon activation, thereby ejecting ink from the nozzle chamber via the ejection port. |
