    • An ink jet print head and a method of manufacturing method thereof are provided to prevent a nozzle layer from swelling during forming the nozzle layer on the chamber layer by forming a through-hole on the chamber layer. An ink jet print head includes a substrate(210), an ink feed hole(211), an ink chamber(213), a chamber layer(212), a through-hole(214), a nozzle layer(216), a nozzle(217), a and solid film resist. The ink feed hole is vertically formed on the substrate. The ink chamber fills with ink flowing through the ink feed hole. The chamber layer is formed on the substrate and confines the ink chamber. The through-hole is formed on the chamber layer and connects the ink chamber to outside for preventing the nozzle layer from swelling. The nozzle layer is formed on the chamber layer and has the nozzle through which the ink inside the ink chamber discharged outside. The nozzle layer and the chamber layer comprise solid film resists for precisely controlling thicknesses of the nozzle layer and the chamber layer respectively.
    • 提供一种喷墨打印头及其制造方法,以通过在腔室层上形成通孔来防止喷嘴层在腔室层形成喷嘴层期间膨胀。 喷墨打印头包括基板(210),供墨孔(211),墨室(213),腔室层(212),通孔(214),喷嘴层(216), 喷嘴(217),固体膜抗蚀剂。 供墨孔垂直地形成在基板上。 墨水室填充流过墨水供给孔的墨水。 室层形成在基板上并限制墨室。 通孔形成在室层上,并将油墨室连接到外部,以防止喷嘴层膨胀。 喷嘴层形成在室层上,并且具有喷嘴,油墨室内的油墨通过喷嘴排出到外部。 喷嘴层和室层包括固体膜抗蚀剂,用于分别精确地控制喷嘴层和室层的厚度。
