Abstract
Disclosed is a fluid ejection device for an inkjet printer that includes a substrate. The substrate includes at least one trench and a plurality of fluid flow vias configured in at least three parallel rows arranged over each trench of the at least one trench. Each row of the at least three parallel rows includes a set of fluid flow vias from the plurality of fluid flow vias arranged in one of a uniform manner and a non-uniform manner such that each fluid flow via of the set of fluid flow vias is configured in a spaced-apart relation with an adjacent fluid flow via. The each fluid flow via is configured in a diagonal relationship relative to a neighboring fluid flow via of an adjacent row of the at least three parallel rows. The fluid ejection device also includes a flow feature layer and a nozzle plate.
