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.
Claims14
A fluid ejection device comprising:
- 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.

A fluid ejection device comprising:
- a thin-film layer on a substrate;
- a primer layer on the thin-film layer;
- a chamber layer on the primer layer that defines chambers;
- a slot extending through the substrate and into the chamber layer through an ink feedhole (IFH) in the thin-film layer;
