The present invention relates to a heat treatment method for stably retaining particles to a certain degree.

Ni-P alloy film with 1% weight is formed in a microcrystalline or amorphous phase and has high resistivity and low temperature coefficient of resistance (TCR), so it is used as a discrete gold jIW/III type electrical resistance material. It is used in parts and hybrid ICs.
ただし、この良好な電気抵抗特性はNi−P合金の微結

これらの構造は熱h学的に準安定状態なので耐熱性に劣

過程が存在することを考慮すると極めて重要な問題であ
る。However, this good electrical resistance property is obtained due to the microcrystalline structure or amorphous structure of the Ni-P alloy.
Since these structures are thermally metastable, they have the disadvantage of poor heat resistance. This is because the resistive material itself becomes a heating element when energized (e.g., a heating resistor typified by a thermal head, which is a printing element for heat-sensitive recording), and its manufacturing and assembly processes are essential. This is an extremely important issue considering that there is a heating process.

温度までの抵抗特性の安定化がなされる。To deal with this problem, eutectoiding (eutectoid) high melting point metals such as W and Mo as third elements into Ni-P alloys is being considered. In particular, eutectoiding of Mo is extremely effective;
In the case of Ni-P alloy, heating up to 300°C reduces the specific resistance, increases TCP and deteriorates the resistance properties, whereas in the case of Ni-Mo-P alloy film, heating up to 300°C - 70°C
Heating at 0° C. increases the specific resistance, and by decreasing TCP, the resistance characteristics are rather improved, and the resistance characteristics are stabilized up to the heating temperature.

The graph shows the results of heating the i-P alloy film and the Ni-Mo-P alloy film in a vacuum furnace at each temperature setting for 1 hour, and measuring the v1 resistance after cooling.

に維持させることを目的としている。The present invention for solving the problems was created based on such technical knowledge, and is formed on a base material by electroless plating with a molybdenum content of 10 to 25% by weight and a phosphorus content of 0.5%. In the method of heat-treating a Ni-Mo-P alloy film with a concentration of ~2.0%, it shortens the heat treatment time, enables local heat treatment of the film, eliminates the effect of heat treatment sealing on the film, and reduces the base density caused by heat treatment. The purpose is to maintain the resistance characteristics of the material stably up to high temperatures while preventing deterioration of the material.

I conducted research related to my work. In general, a pristine Ni-Mo-P alloy film produced by electroless plating shows a crystalline structure in X-ray diffraction, but it actually consists of a crystalline Ni-Mo solid solution phase ([). Non-quality Ni-Mo-
It is composed of two phases: P phase (■ phase}. However, long-term heating using a normal electric furnace etc.
Figure 11 shows the change in resistance characteristics when applied to the o-P alloy film (hereinafter referred to as steady heating).
In this case, the reason why the resistivity increases in heat treatment up to 500° C. is that N1 diffuses from phase 2 to phase 2 and a locally concentrated portion of Mo is generated near the boundary between the two phases. For details, see ■J. Electrochem. Soc.

The development of the present invention was carried out with the view that similar effects could be expected in o-P alloy films, and the following results were obtained.

実用範囲内においては全く同様な効果が得られると言え
る。The present inventors investigated the resistance characteristics and xI! of a sample in which the Ni-Mo-P alloy film was subjected to extremely short pulse heating using Joule heating. When we investigated the compositional change of the phase due to diffraction, we observed a behavior of the resistance characteristics that was almost the same as that of the steady heating method described by Tosho. However, the change in the composition of the phase II due to pulse heating occurs more markedly than during steady heating, and furthermore, the decrease in resistivity G due to heating at a higher temperature after the resistivity reaches its maximum is greater than that during steady heating. However, since it is better for a resistive material to have as high a resistivity as possible, this is not actually a problem because the heat treatment is carried out in a temperature range where a resistivity smaller than this maximum value can be obtained. Therefore, although it is assumed that the mechanism of the effect obtained by pulse heating is slightly different from that of steady heating,
It can be said that exactly the same effect can be obtained within a practical range.

る。Also, although the details will be described later, the highest specific resistance (maximum value described in wJ) obtained by steady heating is 5% with respect to subsequent heating.
The maximum value obtained by pulse heating was stable up to 700°C with respect to subsequent heating. This seems to be the result of a slight difference in the Ni-Mo-P alloy structure obtained by steady heating and pulse heating working in a positive direction. Furthermore, since the processing time is extremely short in pulse heating, the resistance characteristics after heating can be measured immediately, and it has become clear that finer physical properties II and III can be obtained compared to steady heating. Further, physical property v4m by steady heating must be performed before assembling parts, whereas pulse heating allows local heating and can therefore be applied after assembling parts.

る。Effects of the Invention As is clear from the above explanation, according to the method of the present invention in which a Ni-MoP alloy film is subjected to pulse heating, the processing time becomes almost zero compared to the normal heat treatment method.
Since the heating time is 1 hour, the influence of the processing atmosphere can be largely ignored, and there is a great deal of freedom in selecting the material of the base material to be used, for example, the use of synthetic wood Wi base material is also allowed.
In particular, if a laser beam irradiation method or an electron beam irradiation method is used, it is possible to easily heat treat only a local area of the film. ■The physical properties of the film obtained by heat treatment are better than that of conventional long-term heat treatment methods! ■Conventional heat treatment methods require the use of a heat treatment furnace and the need to adjust the heat treatment temperature, resulting in increased heat energy consumption, equipment costs, and other disadvantages; however, the present invention This method simplifies the heat treatment process and also enables post-mounting (post-assembly) heat treatment, which can reduce heat energy costs and equipment costs, as well as improve productivity. Not only does it have the advantage of
-High thermal stability of the resistance properties of the P alloy can be obtained.
