Abstract
One method of fabricating a fluid ejection device comprises forming a heating element on a first surface of a substrate. Adjacent the heating element, a hole is formed through the first surface to define a fill channel. The fill channel is filled with a filler material, and after filled, a fluid chamber is formed over the heating element. The filler material is removed. The fluid chamber is fluidically coupled with the fill channel, and is capable of ejecting fluid heated by the heating element.
