A liquid drop ejector includes a substrate and a plurality of liquid chambers. Portions of the substrate define a liquid supply. Each liquid chamber is positioned over the substrate and includes a nozzle plate and a chamber wall. The nozzle plate and the chamber wall include an inorganic material. The inorganic material of the nozzle plate and the chamber wall is contactable with liquid when liquid is present in each liquid chamber. A region of organic material is positioned over the substrate and located relative to the nozzle plate and the chamber wall such that the region of organic material is not contactable with liquid when liquid is present in each liquid chamber. The region of organic material is bounded by chamber walls of neighboring liquid chambers located on opposite sides of the liquid supply.
