摘要： In an ink jet head using a thermal energy for ejecting ink, this invention aims to reliably and uniformly remove kogations deposited on a heat application portion in contact with the ink. To realize this objective, the upper protective layer is arranged in an area including the heat application portion so that it can be electrically connected to serve as an electrode which causes an electrochemical reaction with the ink. The upper protective layer is formed of a material containing a metal which is dissolved by the electrochemical reaction and which does not form, on heating, an oxide film which hinders the dissolution. With this arrangement, a reliable electrochemical reaction can be produced to dissolve a surface layer of the upper protective layer, thereby removing kogations on the heat application portion reliably and uniformly.

摘要： In an ink jet head circuit board including a heater for generating thermal energy used for ejecting ink in response to application of electricity, a drop in thermal energy efficiency is prevented while reducing an area of the heater to achieve higher-resolution and higher-image-quality printing, and damages on the heater attributable to a manufacturing process are avoided. To achieve this, a resistor layer is disposed on an electrode wire layer; and two protective layers are disposed thereon. Then the upper protective layer is removed in a site above the heater. Accordingly, it is possible to dispose the protective layers without causing a decrease in an effective bubble generating region, and to improve thermal energy efficiency by reducing the effective thickness of the protective layer above the heater. Moreover, the resistor layer is covered with the first protective layer and is thereby prevented from adverse effects in the manufacturing process such as etching processes.

摘要： The present invention provides a substrate for ink jet including a heating resistor generating thermal energy for discharging an ink from an ink discharge port and an upper protective layer which is formed above the heating resistor and has a contacting surface with the ink. Furthermore, the upper protective layer is made of an amorphous alloy consisting of Ta and Cr in which the content of Ta is more than that of Cr. This constitution allows for the substrate excellent in cavitation resistance and corrosion resistance, and capable of high durability while having similar discharge performance to that of a conventional protective layer made of a Ta film. The present invention further provides an ink jet head comprising the above-mentioned substrate, and a manufacturing method thereof.

摘要： An ink jet head circuit board is provided which has heaters to generate thermal energy for ink ejection as they are energized. This circuit board has the heaters formed with high precision to reduce their areas. It also has provisions to protect the electrode wires against corrosion and prevent a progress of corrosion. The substrate is deposited with the thin first electrodes made of a corrosion resistant metal. This is further deposited with the resistor layer. The second electrodes made of aluminum are deposited to overlap the first electrodes to form the heater without causing large dimensional variations among the heaters. With this construction, if a defect should occur in a protective layer on or near the heater, a progress of corrosion can effectively be prevented because the material of the resistor layer is more resistant to encroachment than aluminum and the first electrodes are corrosion resistant.
