MONOLITHIC INK JET PRINT HEAD AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: A monolithic ink jet print head and a method for manufacturing the same are provided to improve linearity and an exhaust characteristic of exhausted ink by integrally forming a nozzle plate with a substrate. CONSTITUTION: A monolithic ink jet print head includes a substrate(110) formed with an ink chamber(132) filled with ink, a manifold(136) for guiding ink into the ink chamber(132), and an ink channel(134) for connecting the ink chamber(132) to the manifold(136). The manifold(136) is positioned at a lower portion of the substrate(110) such that the manifold(136) is located below the ink chamber(132). The ink channel(134) vertically extends by passing through the substrate(110). A nozzle plate(120) is provided at an upper portion of the substrate(110). The nozzle plate(132) forms an upper wall of the ink chamber(132).
