ABSTRACT:
A method of fabricating a plurality of inkjet nozzles on a substrate. The method comprises the steps of: (a) providing a substrate having a plurality of trenches corresponding to ink inlets; (b) depositing sacrificial material so as fill the trenches and form a scaffold on the substrate; (c) defining openings in the sacrificial material; (d) depositing roof material over the sacrificial material to form nozzle chambers and filter structures simultaneously; (e) etching nozzle apertures through the roof material; and (f) removing the sacrificial material.
