ABSTRACT:
A fluid ejection device comprising a substrate having a first surface, and a fluid ejector formed over the first surface. A top layer is also formed over the first surface of the substrate and defines a chamber about the fluid ejector. The top layer also defines a fluid channel that directs fluid into the chamber. In one embodiment, a barrier feature is positioned within the fluid channel, and has a height that is less than the height of the fluid channel.
