Abstract

A fluid ejector having a first surface, a second surface, and an orifice that allows fluid in contact with the second surface to be ejected. The fluid ejector has a non-wetting layer exposed on at least a first surface of the fluid ejector, and a overcoat layer exposed on a second surface, the overcoat layer being more wetting than the non-wetting layer. Fabrication of this apparatus can include depositing a non-wetting layer on the first and second surfaces, masking the first surface, optionally removing the non-wetting layer from the second surface, and depositing an overcoat layer on the second surface.
