Abstract
A micro-fluid ejection device structure, a multi-fluid cartridge containing the ejection device structure, and methods for making the ejection device structure and cartridge. The ejection device includes an ejection head substrate having a fluid supply side and a device side and containing two or more fluid flow paths therein for supplying fluid from the fluid supply side to the device side thereof. A multi-channel manifold is attached to the fluid supply side of the ejection head substrate for providing fluid from two or more fluid reservoirs to the fluid flow paths in the ejection head substrate. The multi-channel manifold has fluid flow channels therein in fluid flow communications with the fluid flow paths in the ejection head substrate and the manifold consists essentially of a patterned photoresist material.
