Abstract
A method of manufacturing an inkjet print head simplifies a manufacturing process and uniformly forms an ink channel and includes forming a chamber layer using a low-speed optical hardening material on a substrate, hardening regions of the chamber layer for the wall of an ink channel by selectively exposing the chamber layer to light, forming a nozzle layer using a high-speed optical hardening material, having a higher optical reaction speed than that of the low-speed optical hardening material, on the chamber layer, hardening regions of the nozzle layer other than nozzles by selectively exposing the nozzle layer to light, and forming the ink channel and the nozzles by developing the chamber layer and the non-exposed regions of the nozzle layer.
