Abstract:
1. A method of manufacturing an inkjet head, the method comprising: manufacturing an ink chamber substrate having pressure chambers, a diaphragm substrate having a diaphragm for pressurizing the pressure chambers, and an orifice substrate having nozzle holes for ejecting ink, each of ink chamber substrate, the diaphragm substrate, and the orifice substrate being formed from silicon material; forming a silicon dioxide (SiO forming a glass layer on a surface of the silicon dioxide (SiO forming an oxygen-deficient silicon oxide (SiO anodically bonding the diaphragm substrate, orifice substrate, and ink chamber substrate by sequentially laminating the diaphragm substrate, ink chamber substrate, and orifice substrate and applying a DC voltage across the ink chamber substrate, the diaphragm substrate, and the orifice substrate.
