Ink jet printer nozzle plate and process therefor |
摘要 |
The invention provides a printhead for an ink jet printer and a method for making a printhead for an ink jet printer. The printhead includes a semiconductor substrate containing ink ejection devices and a dry-etched ink via therein. A first photo-imaged polymer layer is applied to the semiconductor substrate, the first photo-imaged polymer layer being patterned and developed to contain ink flow chambers and ink flow channels corresponding to the ink ejection devices on the semiconductor substrate. A second photo-imaged polymer layer is applied to the first photo-imaged polymer layer. The second photo-imaged polymer layer is patterned and developed to contain nozzle holes corresponding to the ink chambers in the first photo-imaged polymer layer and corresponding to the ink ejection devices on the semiconductor substrate. The invention provides increased printhead manufacturing accuracy and elimination of alignment and adhesive attachment of a separate nozzle plate to an ink jet heater chip.
