Abstract
A fluid ejector having an inner surface, an outer surface, and an orifice that allows fluid in contact with the inner surface to be ejected. The fluid ejector has a non-wetting monolayer covering at least a portion of the outer surface of the fluid ejector and surrounding an orifice in the fluid ejector. Fabrication of the non-wetting monolayer can include removing a non-wetting monolayer from a second region of a fluid ejector while leaving the non-wetting monolayer on a first region surrounding an orifice in the fluid ejector, or protecting a second region of a fluid ejector from having a non-wetting monolayer formed thereon, wherein the second region does not include a first region surrounding the orifice in the fluid ejector.
