    摘要: 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.
