Abstract: An ink jet head circuit board is provided which has heaters to generate thermal energy for ejecting ink as they are energized. This circuit board is so constructed as to reduce wire resistances for the heaters while at the same time preventing an increase in the size of the board and realizing a high-density integration of the heaters required for high resolution printing. This construction is made possible by forming electrode wires of first and second electrode wire layers to reduce an area that the wire patterns for the heater occupy on the circuit board. In reducing the effective thickness of protective insulation layer formed on the heater to prevent a possible degradation of thermal efficiency, one of the protective insulation layers over the electrode wires is removed from the heater, depending on the thickness of the electrode wires.

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 is formed of two layers and one of the two layers is removed from above the heater to improve the heat energy efficiency. The resistor layer is deposited over the electrode wire layer. The patterning for removing the protective insulation layer is done in a wider range than a gap of the electrode wire layer, 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 can be prevented.

Abstract: A semiconductor device includes a lateral end surface and a connection electrode for external electrical connection. The connection electrode is exposed at the side surface. A manufacturing method of the semiconductor device includes steps of forming a linear recess in a silicon substrate between adjacent semiconductor devices, forming, on an inner surface of the recess, the electrode for external electrical connection of one of the semiconductor devices, and a step of separating the one semiconductor device from another on the silicon substrate by cutting the silicon substrate along the linear recess. Forming the electrode includes steps of forming a metal thin film astride a cutting line at which the silicon substrate is to be cut, forming a resist layer and patterning the resist layer on the metal thin film, growing metal at a portion not having the patterned resist layer, and removing the patterned resist layer and the metal thin film below the patterned resist layer.

Abstract: 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.

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 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.
