    Abstract: In an embodiment, a fluid ejection device includes a thin-film layer formed over a substrate. A primer layer is formed over the thin-film layer, and a chamber layer is formed over the primer layer that defines a fluidic channel leading to a firing chamber. The fluid ejection device includes a slot that extends through the substrate and into the chamber layer through an ink feed hole in the thin-film layer. The fluid ejection device also includes a particle tolerant extension of the primer layer that protrudes into the slot. In some implementations, the particle tolerant primer layer extension extends across a full width of the slot.

    Abstract: In an embodiment, a method of forming a printhead includes forming on a front-side surface of a substrate, a thin film layer and a plurality of fluidic channels and ejection chambers. The method also includes forming a slot through the substrate from the back-side surface to the front-side surface, where the back-side and front-side surfaces generally oppose one another. The slot has a length extending along a long axis of the substrate and a width extending along a short axis of the substrate. The method includes forming recessed regions into the back-side surface of the substrate at both ends of the slot that extend beyond the length of the slot.

    Abstract: In one example implementation, a printhead die includes a SiO2 layer grown into a surface of a silicon substrate, a dielectric layer formed on the surface over an interior area of the substrate, a first termination ring surrounding the interior area and defined by an absence of the dielectric layer, a berm surrounding the first termination ring and defined by the presence of the dielectric layer, a damage detection conductor formed under the berm on the SiO2 layer, and a second termination ring surrounding the berm and defined by an absence of the dielectric layer.
