Abstract: 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 reduces areas of the heaters to achieve higher printing resolution and image quality. This board also prevents a degradation of thermal energy efficiency and reduces power consumption. The protective insulation layer for the electrode wire layer (103) is formed of two layers (108a,108b) and one of the two layers, (108a), is removed from above the heater (102) to improve the heat energy efficiency. The resistor layer (107) is deposited over the electrode wire layer (103). The patterning for removing the protective insulation layer (108a) is done in a wider range than a gap of the electrode wire layer (103), the gap being used to form the heater. Further, by forming the electrode wires in two layers, a possible reduction in an effective bubble generation area of the heater (102) can be prevented.

Abstract: An ink jet head circuit board is provided which has heaters to generate thermal energy for ink ejection. This board has the heaters formed with high precision to reduce their areas. It has provisions to protect the electrode wires against corrosion and prevent a progress of corrosion. The substrate is deposited with the thin first electrodes (101) made of a corrosion resistant metal. Over the first electrodes the second electrodes (103) made of aluminum are formed. The second electrodes are deposited with a resistor layer (107). The heater is formed in the gap between the first electrodes. With this construction, the heaters are formed without large dimensional variations among them. Should a defect occur in a protective layer above or near the heaters, 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.

Abstract: 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.

Abstract: This invention relates to a printhead substrate capable of suppressing an increase in wiring width and an increase in the size of a substrate formed by a film forming process while increasing the number of simultaneously driven printing elements in order to improve the printing performance, a printhead using the substrate, and a printing apparatus using the printhead. The wiring lines of the substrate are formed into a common wiring line, and energy applied to a heating resistance element is prevented from deviating from a stable ink discharge range owing to the difference in the number of simultaneously driven heating resistance elements. For this purpose, a driving element is greatly downsized in comparison with a conventional one, and the operation region of a MOS transistor is shifted from the non-saturation region to the saturation region.
