Abstract: Provided is a method of manufacturing an inkjet printhead. The method includes: preparing a substrate having thereon a heater for heating ink and an electrode for supplying current to the heater; applying a negative photoresist composition to the substrate having thereon the heater and the electrode and patterning the same to form a passage forming layer that surrounds an ink passage; patterning the substrate having thereon the passage forming layer by photolithography at least twice to form a sacrificial layer having a planarized upper surface in a space surrounded by the passage forming layer; applying the negative photoresist composition to the passage forming layer and the sacrificial layer and patterning the same to form a nozzle layer having a nozzle; etching the substrate from the rear surface thereof to be perforated to form an ink supply hole; and removing the sacrificial layer, wherein the negative photoresist composition includes a prepolymer that has a glycidyl ether functional group or a ring-opened glycidyl ether functional group on monomer repeating units thereof and a phenolic novolak resin-based backbone, a bisphenol A-based backbone, or an alicyclic-based backbone. The sacrificial layer may be planarized using a chemical mechanical polishing process. Therefore, an upper surface of the sacrificial layer can be planarized, and thus, it is possible to easily control a shape and dimension of an ink passage, thereby improving uniformity of the ink passage.

Abstract: An inkjet printer head and method of fabricating the same includes a substrate having an ink-feed hole formed at a bottom surface of the substrate, a lower chamber formed at a top surface of the substrate, and a restrictor to fluid communicate between the ink-feed hole and the lower chamber, an oxide layer formed on the substrate, a heater formed on the oxide layer and disposed parallel to the surface of the substrate to cross the lower chamber, a lead electrically connected to the heater, and a nozzle layer disposed on the heater to configure an ink channel together with the lower chamber and having a nozzle at an upper portion of the nozzle layer. The inkjet printer head is capable of improving a thermal efficiency by heating the ink using both surfaces of the heater since the heater is disposed at a center of the ink chamber, and improving characteristics of the heater by making a current density and a current flow uniform since the heater is formed in a straight line without any bent or curved portion.
