Fluid ejection device having a substrate to filter fluid and method of manufacture

摘要

A fluid ejection device is described. One exemplary embodiment includes a substrate having a first surface and a second surface, the substrate defines a fluid supply conduit between the first surface and the second surface. This particular fluid ejecting device also includes a generally elastic filter layer formed over the first surface where the filter layer does not form sidewalls defining a fluid channel of the fluid ejection device.
