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 22):
The fluid ejection device of  claim 21 , wherein the laser machining the substrate comprises laser machining the substrate a first width to a first depth followed by laser machining the substrate a second width for an additional, second depth to form a portion of the opening, wherein the first width is greater than the second width, and the second depth is less than the first depth.
