Patent ID: 7086154

Claim:
A process of manufacturing a nozzle plate for an ink-jet print head, said nozzle plate including (a) a substrate having an outside surface which is to be opposed to a print media, an inside surface which is opposite to said outside surface and nozzle holes which are formed through said substrate so as to be open in said outside and inside surfaces, and (b) a non-wetting layer which has a non-wetting characteristic and which covers said outside surface of said substrate, said process comprising: a masking step of applying a resist on said inside surface of said substrate, and charging said nozzle holes with said resist such that portions of said resist protrude outwardly from openings of said nozzle holes on said outside surface; a non-wetting-layer forming step of forming said non-wetting layer on said outside surface in a plating operation; and an unmasking step of removing said resist from said nozzle holes after forming said non-wetting layer.
