Barrier feature in fluid channel

摘要

A fluid ejection device 103 comprising a substrate 115 having a first surface, and a fluid ejector 201 formed over the first surface. A top layer 124 is also formed over the first surface of the substrate and defines a chamber 202 about the fluid ejector. The top layer also defines a fluid channel 203 that directs fluid into the chamber. In one embodiment, a barrier feature 300 is positioned within the fluid channel, and has a height that is less than the height of the fluid channel.
