Inkjet printhead with supply ducts in reverse side of water

摘要

An inkjet printhead with an array of nozzles formed on and through a wafer substrate using lithographically masked etching and deposition techniques, each nozzle having a drop ejection actuator and an associated drop ejection aperture in order to eject drops of the liquid from one side of the wafer substrate. Each of the nozzles in the array are supplied with the liquid from ducting that is etched into the opposite side of the wafer substrate.
