Abstract:
A method of forming a substrate for a fluid ejection device includes forming an opening in the substrate from a second side toward a first side, and further forming the opening in the substrate to the first side, including increasing the opening to the first side and increasing the opening at the second side, and forming the opening with substantially parallel sidewalls intermediate the first side and the second side and converging sidewalls to the first side.

Claim (Index 19):
The fluid ejection device of  claim 16 , wherein the substrate comprises a silicon substrate, and the converging sidewalls comprise <111> planes of the silicon substrate from the parallel sidewalls to the first side and the diverging linear sidewalls comprise <111> planes of the silicon substrate from the parallel sidewalls to the second side.
