摘要： A manufacturing method for a device having an electrostatic actuator for example inkjet head, whereby warping of the diaphragms does not occur as a result of anodic bonding is provided. The method comprises the steps of etching a first substrate on the first surface thereof to form a concave portion and a diaphragm provided in bottom walls of the concave portion, forming an electrode on a second substrate, and anodically bonding the second substrate to a second surface of the first substrate, opposite the first surface, such that the electrode is aligned adjacent to the diaphragm with a gap therebetween. The bonding temperature of the anodically bonding step is set within a temperature range whereby the contraction of the first substrate after bonding is equal to or greater than the contraction of the second substrate.

摘要： An electrostatic actuator comprising opposing electrode members displaced relatively by an electrostatic force is provided with improved durability so that electrostatic attraction between opposing members does not drop and the opposing electrode members do not stick together. Hydrophobic films of hexamethyldisilazane (HMDS) are formed on a surface of segment electrode and a bottom surface of a diaphragm (common electrode) of an eletrostatic actuator wherein the diaphragm forms a wall of an ink chamber in an ink jet head. HMDS molecules are smaller than PFDA molecules, and a uniform, variation-free hydrophobic film can therefore be formed even when the gap between opposing electrodes is narrow. Durability and film stability of a HMDS hydrophobic film are also high. An electrostatic actuator with high durability and operating stability can thus be achieved.

摘要： Methods for manufacturing an electrostatic actuator that comprises electrode members having opposing surfaces with a gap disposed therebetween. In an ink jet head, a bottom surface of a diaphragm may be one of the electrodes (common electrode) of an eletrostatic actuator, the diaphragm forming a wall of an ink chamber in the ink jet head that is displaced relatively by an electrostatic force. A hydrophobic film, preferably hexamethyldisilazane (HMDS), is formed on at least one of the opposing electrode surfaces to improve the durability of the electrostatic actuator so that electrostatic attraction between opposing electrode members does not decrease and the opposing electrode members do not stick together. HMDS molecules are smaller than PFDA molecules, and a uniform, variation-free hydrophobic film can therefore be formed even when the gap between opposing electrodes is narrow. Durability and film stability of a HMDS hydrophobic film are also high. An electrostatic actuator with high durability and operating stability can thus be achieved.
