A fluid ejection device may include a fluid ejection die including nozzles and fluid feed holes. Each nozzle may have a nozzle orifice formed in a top surface of the fluid ejection die. The fluid feed holes may be formed in a bottom surface of the fluid ejection die and fluidly connected to the nozzles. The fluid ejection device may include a molded panel into which the fluid ejection die is at least partially embedded, the molded panel having a fluid slot formed therethrough such that the fluid slot is fluidly connected to the fluid feed holes of the fluid ejection die, the molded panel formed with a mold chase and a release liner coupled to and at least partially covering an interior surface of the mold chase, the mold chase having a fluid slot feature corresponding to the fluid slot.
