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.

Abstract: A method for manufacture of an ink jet head comprises the process of forming a head main body by providing a positive resist layer to constitute ink passages for a substrate having ink ejection pressure generating means and then a ceiling member therewith; forming a carbon-contained film for the surface where the ink discharging ports of the head main body are formed; conducting a fluoric plasma treatment given to the carbon-contained film by utilizing a hydrofluoride compound; and removing the positive resist layer. With this method, an F-C coupled water repellent film is formed on the discharging port formation surface of an ink jet recording head evenly with a desirable bonding capability to enhance the reliability of water repellency.
