所定のパターン膜を得る方法が知られている。In recent years, precise patterns have become necessary for precision mechanical parts and electronic parts, and the processing method for this is called photolithography, in which the unprocessed parts of the material surface are coated with a chemical-resistant film and the unnecessary parts are removed. There is a method of forming patterns by etching, and a method called 7-o-7-oh mink.
A method is known in which a desired pattern film is obtained by depositing a desired material on a film of a negative pattern by a method such as electroplating or chemical plating, and then removing the film.

There are problems such as slow etching speed, high cost, difficulty in controlling etching conditions and treatment of etching solution, and unavoidable side etching effects. In addition, with the conventional 70 to 7 ohming method, it is difficult to form patterns on metals that hardly exhibit an electrodeposition reaction, metals that are difficult to chemically plate, ceramics, and the like.

ができる。FIG. 1 is a plan view of a print head portion of a printer (discharge printer or current transfer printer) having an electrode 1 made of a tungsten layer on a substrate 2. As shown in FIG. Conventionally, when forming such an electrode, a tungsten layer 3 is formed on the substrate 2 (see FIG. 4) as shown in FIG.
A fine pattern 4 of photoresist (polyimide) was formed (a) in the same figure, unnecessary portions were removed by etching (b), and 7e) renost was removed (c). In contrast, in the present invention, as shown in FIG. 2, a fine pattern 4 of photorenost is formed directly on the substrate 2.
Next, tungsten plasma spraying is carried out to form a tungsten layer 5 (FIG. 2B), and then the othrenost layer 7 is peeled off (FIG. 1C). According to this process, a fine pattern of high quality can be obtained with high efficiency.

冷却装置15からなる。Thermal spraying is a method of melting or semi-melting a coating material and spraying it onto a substrate at high speed to form a film on the substrate surface. Plasma spraying involves ejecting plasma (a highly ionized, high-temperature gas that is electrically neutral as a whole) from a thin nozzle, then injecting a powdered material into the plasma jet, which melts and flies the jet. , which is adhered to and laminated on the surface of a substrate to form a film. As shown in Fig. 61 or @5 of this device,
Plasma spraying that generates a plasma jet〃10,
A high frequency starter 11 for starting arc generation, a DC power supply 12 as an energy supply source for sustaining the arc, a control VC device 13 for supplying and controlling the arc gas and controlling the electrical system, and supplying powder material to the plasma jet. It consists of a hopper 14 and a cooling device 15 to protect the hopper from high temperatures.

ストで皮膜を得ることが出来るものである。This plasma spraying can coat high-melting point materials because the plasma jet temperature is high, and because the plasma jet flow rate is high, the collision energy of the molten particles is large and a dense coating with strong bonding force is obtained, which does not deteriorate the mechanical strength of the material. Since it does not cause thermal distortion and the coating speed is fast, it is possible to obtain a film at low cost.

A plating film of nickel, copper, etc. is formed on the photoresist,
In order to obtain a stable film, it is extremely preferable to pattern the plating film by removing the photorenost and then perform the plasma spraying on top of the pattern.
