Abstract

This invention is directed to a process for manufactur­ ing thermal ink jet printheads wherein a polymer barrier layer is employed between a thin film resistor (TFR) sub­ strate and a metal nozzle plate and serves as both the ink reservoir-defining material and the adhesive bonding mech­ anism for firmly securing these members one to another. The polymer barrier layer material is initially U.V. cured, then partially thermally cured in a heat staker and finally completely thermally cured in an oven. The surface contour of the barrier layer follows that of the nozzle plate and TFR substrate and thereby prevents any gaps from occurring in this composite structure. This feature in turn enhances the structural integrity of the printhead, enhances its lifetime to and improves its frequency response. Repeatability of manufacturing and a more consistent drop volume ejection from printhead to printhead is also achieved.
