Abstract: In some examples, a fluidic die includes fluidic actuators, switches, and electrically conductive lines in an electrically conductive layer of the fluidic die. The electrically conductive lines electrically connect the switches to respective actuators. A first dimension of a first electrically conductive line is different from a second dimension of a second electrically conductive line to match a first resistance of the first electrically conductive line having a first length to a second resistance of the second electrically conductive line having a second length different from the first length.

Abstract: In one example in accordance with the present disclosure, a fluidic die is described. The fluidic die includes a surface on which a number of nozzles are formed. An electrical interface on the fluidic die establishes an electrical connection between the fluidic die and a fluidic die controller. The electrical interface includes 1) a bond pad disposed within a bond pad region of the surface and 2) an electrical lead coupled to the bend pad to establish an electrical connection between the fluidic die and the fluidic die controller. The fluidic die also includes a beveled edge along an edge of the surface underneath the electrical lead.

Abstract: Fluid ejection devices with particle tolerant thin-film extensions are disclosed. An example apparatus includes a printer; a reservoir; and a printhead including: a firing chamber; a channel to receive fluid from the reservoir, the channel is coupled to the firing chamber, the channel having an opening; and a particle-tolerant film disposed adjacent the opening of the channel, the particle-tolerant film disposed between the channel and the reservoir, the particle-tolerant film to deter particles within the fluid from settling in an area adjacent the opening.

Abstract: A printhead die includes a SiO2 layer grown into a surface of a silicon substrate, and a dielectric layer deposited onto an interior surface area of a substrate. Multiple termination rings are formed around the interior surface area. Each ring is defined by an absence of the dielectric layer. A berm is located in between each termination ring. Each berm is defined by the presence of the dielectric layer.

Abstract: In an embodiment, a fluid ejection device includes a thin-film layer formed over a substrate, a chamber layer formed over the thin-film layer, the chamber layer defining a fluidic channel that leads to a firing chamber, a slot extending through the substrate and into the chamber layer through an ink feed hole in the thin-film layer, and a particle tolerant thin-film extension of the thin-film layer that protrudes into the slot from between the substrate and the chamber layer.

Abstract: In one example, a printhead structure includes a cover covering an underlying structure. The cover and the underlying structure define multiple chambers from which fluid may be dispensed through nozzles in the cover and the cover has a stepped edge profile along at least part of the perimeter of the cover.
