Abstract: 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.

Abstract: An Al layer of wiring material is etched using an alkaline aqueous solution. There are provided a method for producing a thin film resistor, in which only the Al layer can be selectively etched independent of a resistor layer using the alkaline aqueous solution, an anti-sticking means for film-forming apparatus having the structure which can prevent a drop in yield due to particles, even with less frequency of cleaning for a film-forming chamber, and a film-forming apparatus provided with the anti-sticking means. When the wiring electrode layer mainly containing Al is etched by the alkaline aqueous solution, only the Al layer can be selectively etched without etching the resistor layer, which can reduce a change in resistance of resistor, improve the yield and the productivity, and raise the reliability of the thin film resistor. Also, when the anti-sticking means having a tongued-and-grooved surface is set in the film-forming chamber of the film-forming apparatus, the film-forming material is deposited in a discontinuous manner on the anti-sticking means, which can delay the time of film exfoliation, in turn extend the cycle of cleaning for the anti-sticking plate, and prevent the drop in yield due to the film exfoliation.
