    摘要： A method for manufacturing an orifice plate used for a liquid discharge provided with discharge port for discharging liquid comprises the steps of preparing a non-conductive plate having recessed portion formed on the circumference of the flat portion corresponding to the discharge port, forming a first conductive material peelable from the non-conductive plate only in the recessed portion of the non-conductive plate, forming a plate member by plating the first conductive material with a second conductive material by electroforming method after the formation of the first conductive material, and obtaining the orifice plate having the discharge port by peeling off the plate member from the non-conductive plate. With the method thus arranged, it is possible to materialize the same precision as in the glass mask used for photolithography, and make the variation of orifice areas smaller for the formation of highly densified orifices.

    摘要： Patterning is performed to thermal oxide films 12a and 12b formed on both surface sides of a silicon substrate in which crystal orientation of a surface is (100) or (110), a liquid chamber pattern and a liquid supplying port pattern are formed, and a liquid chamber and a liquid supplying port are formed separately by anisotropically etching the silicon substrate from both surface sides at the same time. Then, a silicon nitride film is deposited with a low pressure chemical vapor deposition to both surface sides of the silicon substrate and all faces of the liquid chamber and the liquid supplying port which are formed by etching. As a result, when the silicon substrate is used for a top plate, stiffness of the top plate is improved, design freedom of the liquid chamber and the liquid supplying port is increased, misalignment is prevented in bonding to the substrate, degradation of ejecting performance is prevented, and a liquid discharge head having high preciseness and high reliability can be provided.

    摘要： A method for manufacturing liquid discharge heads is provided with discharge ports for discharging liquid, liquid flow paths communicated with the discharge ports for supplying liquid to the discharge ports, a substrate having heat generating members for creating bubbles in liquid, and movable members facing the heat generating members, each being arranged in each liquid flow path, having the free end on the discharge port side with a specific gap with the heat generating member. This method comprises the steps of forming the boundary layer used for providing a gap between the movable member and the substrate above the heat generating member on the substrate, of laminating the movable member on the boundary layer so as to position the free end above the heat generating member, at the same time fixing the movable member on the substrate, and of forming the gap between the movable member and the heat generating member by use of the boundary layer. With the structure thus arranged, there is no need for the step to position the movable member with the substrate, and also, the movable portion of the movable member is separated from the substrate after the movable member is formed on the substrate and incorporated in the liquid discharge head so as to implement arranging the interior of each liquid flow path finer and more precisely.

    摘要： A liquid ejection head cartridge includes a liquid ejecting head and a liquid container. The liquid ejection head includes an ejection outlet, a bubble generation region, and a movable member disposed faced to the bubble generation region and displaceable between a first position and a second position further from the bubble generation region than the first position. The movable member moves from the first to the second position by pressure produced by the generation of a bubble to permit expansion of the bubble more in a downstream side closer to the ejection outlet. The liquid container includes a substantially prism-like outer wall provided with a substantial air vent portion and having a corner, and an inner wall having a prism-like shape with outer surfaces substantially equivalent to inside surfaces of the outer wall and having a corner portion corresponding to the corner of the outer wall, the inner wall being separable from the outer wall and defining a liquid accommodating portion for containing liquid, the inner wall further having a liquid supply portion for supplying the liquid out of the liquid accommodating portion to the liquid ejection head. The inner wall has a thickness which is smaller in the corner portion than a thickness of a central portion of the outer surfaces of the inner wall.
