ABSTRACT:
In one embodiment, a fluid ejection device comprises a substrate having a first surface, and a fluid slot in the first surface. The device further comprises a fluid ejector formed over the first surface of the substrate, and a chamber layer formed over the first surface of the substrate. The chamber layer defines a chamber about the fluid ejector, wherein fluid flows from the fluid slot towards the to be ejected therefrom. The chamber layer has a discontinuity, wherein the discontinuity is positioned over the fluid slot.
