A substrate for a fluid ejection device includes a first side, a second side opposite the first side, and a fluidic channel communicating with the first side and the second side. A first portion of the fluidic channel extends from the first side toward the second side, a second portion of the fluidic channel extends from the second side toward the first side, and a third portion of the fluidic channel extends from an interface between the first portion and the second portion of the fluidic channel toward the second side. |
