METHOD OF MANUFACTURING AN INK-JET PRINTHEAD |
摘要 |
A method of manufacturing an ink jet printhead includes: providing a silicon substrate including active ejecting elements; providing a hydraulic structure layer; providing a silicon orifice plate having a plurality of nozzles for ejection of said ink; and assembling the silicon substrate with said hydraulic structure layer and said silicon orifice plate. Providing the silicon orifice plate comprises: providing a silicon wafer having a substantially planar extension delimited by a first and a second surfaces; performing a thinning step at the second surface so as to remove a central portion having a preset height; and forming in the silicon wafer a plurality of through holes, each defining a respective nozzle for ejection of the ink. |
