摘要： In one embodiment, a fluid ejection device comprises a substrate having a fluid slot defined from a first surface through to a second opposite surface; an ejection element formed over the first surface and that ejects fluid therefrom; and a filter having feed holes positioned over the fluid slot near the first surface. Fluid moves from the second surface through the feed holes to the ejection element. In a particular embodiment, the filter is formed of a first material that is surrounded by a second material. In another particular embodiment, the filter is formed from the back side and is formed of the same material as the substrate.
