LIQUID DISCHARGE HEAD, MANUFACTURING METHOD THEREOF, AND MICROELECTROMECHANICAL DEVICE |
摘要 |
There is provided a liquid discharge head comprising a substrate, a ceiling plate connected to the substrate, a liquid flow path formed between the substrate and the ceiling plate, and a cantilever-like movable member having a fixed end fixed to the substrate and a free end extending into the liquid flow path, wherein the movable member is formed of a lower protective layer, a heat generating resistive layer, a lower electrode layer, an insulating layer, an upper electrode layer, and an upper protective layer stacked from the side of the substrate in the mentioned order, and wherein application of a voltage to a heat generating portion of the heat generating resistive layer causes bubbling of a liquid in the liquid flow path between the movable member and the substrate to discharge the liquid.
