Abstract:
In an embodiment, a fluid ejection device includes a substrate with a fluid slot formed therein, a chamber layer formed on the substrate defining fluid chambers on both sides of the fluid slot, a thin-film layer between the substrate and chamber layer that defines an ink feedhole (IFH) between the fluid slot and the chamber layer, and a chamber layer extension that forms a bridge across the IFH between two chambers.
