Abstract
A method of forming a nozzle plate of a fluid ejection device includes etching a bore in the first side of the multi-layer substrate, depositing a liner in the bore, removing a layer from a second side of the multi-layer substrate, wherein the removing exposes a closed end of the liner, applying a non-wetting coating to the closed end of the liner and an area surrounding the closed end of the liner, and removing the closed end of the liner, wherein removing the closed end of the liner opens a nozzle.
