Abstract:
A method for producing an electrostatically-driven ink jet head, comprising the steps of:(A) etching a first surface of a silicon substrate to define an ink ejection chamber therein, the ink ejection chamber including a deformable diaphragm interposing the first and an opposing second surface of the silicon substrate;(B) patterning a gap-spacing section of a substantially uniform thickness on the second surface of the silicon substrate circumscribing the diaphragm;(C) bonding a first insulating substrate to the first surface of the silicon substrate;(D) forming an electrode on a surface of a second insulating substrate;(E) aligning the silicon substrate and the second insulating substrate such that the gap-spacing section disposed on the second surface of the silicon substrate and the surface of the second insulating substrate are juxtaposed with the diaphragm and the electrode substantially overlapping; and(F) anodically bonding the silicon substrate and the second insulating substrate together to form a multilayered structure having the diaphragm and electrode separated by a distance including the thickness of the gap-spacing section.
