A method of manufacturing a liquid discharge head including a plurality of passages on a substrate, the passages communicating with a plurality of discharge ports configured to discharge liquid. The method includes the step of forming first, second, third, and fourth members, the first member having a shape of one passage, the second member having a shape of another member, the third member being formed near the first member, the fourth member being formed near the second member, the first to fourth members being formed on a surface of the substrate. The method also includes coating the substrate with a cover layer covering the first to fourth members, removing the first member to form the one passage, and removing the second member to form the another passage.

A method of manufacturing a liquid discharge head including a plurality of passages on a substrate, the passages communicating with a plurality of discharge ports configured to discharge liquid. The method includes the step of forming first to fourth patterns, the first pattern having a shape of one passage of the passages, the second pattern having a shape of other passage of the passages, the third pattern being formed near the first pattern, the fourth pattern being formed near the second pattern, the first to fourth patterns being formed on the substrate. The method also includes coating the substrate with a cover layer covering the first to fourth patterns, removing the first pattern to form the one passage, and removing the second pattern to form the other passage.
摘要:
A manufacturing method of an ink jet recording head includes steps of forming a liquid flow path mold material of a soluble resin on a substrate on which an energy generating element is formed, the energy generating element being configured to generate energy for use in discharging ink; forming a coating resin layer of a negative photosensitive resin on the substrate on which the mold material is formed; exposing and developing the coating resin layer to form an ink discharge port in the coating resin layer; and dissolving and removing the mold material to form a liquid flow path. During the exposing of the coating resin layer, a total amount of exposure energy per unit area applied to an exposure region other than a region of the coating resin layer positioned above the mold material is greater than that of exposure energy per unit area applied to the region of the coating resin layer positioned above the mold material.
