摘要:
An inkjet print head and method of fabricating the same. The inkjet print head includes: a substrate having an ink-feed hole, an interlayer dielectric layer formed around the ink-feed hole on the substrate, at least one metal layer formed on the interlayer dielectric layer, and an anti-moisture part formed between the ink-feed hole and the at least one metal layer to prevent ink moisture in the ink-feed hole from contacting the at least one metal layer. The inkjet print head and the method of fabricating the same are capable of preventing problems such as de-lamination between layers, electrical short-circuit, circuit malfunction, and corrosion of a metal interconnection layer, since it is possible to prevent penetration of ink moisture from layers having absorbent characteristics into the metal interconnection layer, a logic region, or a pressure driving part. Therefore, it is possible to improve the lifespan and reliability of the inkjet print head as well as to increase productivity and reduce manufacturing cost by increasing yield.
