It is also known that similar electrical properties are found in transition metal oxides, such as hematite, magnetite, nickel ferrite, nickel zinc ferrite,
Nickel oxide etc. have been reported. These conventional nonlinear resistance elements use materials in the form of thin films or sintered bodies, but it is advantageous to construct them with thin films from the viewpoint of low threshold voltage, and they exhibit relatively stable characteristics. Most amorphous semiconductor devices are of the thin film type.

In either case, the active layer is usually formed by vacuum evaporation or sputtering.

合物を見出し、これをアクティブ層に用いた。Means for Solving the Problems In order to achieve the above object, the present invention adopts a method of applying a solution of a metal compound and thermal decomposition to form an active layer. As a metal compound, it dissolves in an appropriate solvent,
It only needs to form a film when the solution is applied and dries.
For example, inorganic acid salts such as nitrates, organic acid salts such as acetates,
Complexes and organic metals with an alkyl group attached to the metal can be used. Although there are many compounds that can be used to form thin films using this method, the inventors found a mixture of manganese oxide and tin oxide as a compound that exhibits switching properties, and used this for the active layer.

Since methods such as dipping, spraying, and printing can be used, a uniform film can be manufactured over a large area with high productivity and at low cost. In addition, the thin film obtained by pyrolysis exhibits switching characteristics in which the threshold voltage and sustaining current change depending on the film thickness, distance between electrodes, composition, etc., and the stability of these characteristics is very good.

A coating solution for forming a thin film of a mixture of manganese oxide and tin oxide was prepared with the composition shown in the table. As the compound of manganese and tin, 2-ethylhexanoate, which is very easy to form into a film, was used, and as the solvent, methyl in butyl ketone was used. These coating solutions were spin-coded onto a glass substrate on which a thin gold film was formed as an electrode, dried at room temperature, and exposed to air for 65 minutes.
The active layer is formed by heating and baking at 0°C for 60 minutes,
Furthermore, a gold thin film was formed on this thin film. When the I-4 characteristics of these elements when a voltage is applied are measured with a curve tracer, a sharp I-4 curve shown in FIG. 1 is obtained.

The manufacturing method other than the electrodes is the same as in Example 1. When these I-y characteristics were measured with a curve tracer, an IV curve as shown in FIG. 1 was similarly obtained, and the results are shown in Table 2. The sample magnets in the table correspond to those in Table 1, and the same ones indicate that the active layer was formed using the same coating solution. The sweep frequency is cs

An active layer was formed using the same coating solution as in Example 1. The formation conditions are the same as in Example 1. In this way, the Brehner type element shown in FIG. 3 was produced. When DC voltage was applied to these and the IV characteristics were measured, the first
An I-4 curve as shown in the figure was obtained. The results are shown in Table 3. Similarly, the sample locus corresponds to that of Example 1. It can be seen that the threshold voltage increases in response to the larger inter-electrode spacing compared to the sandwich type element. It was confirmed that the stability of the properties in these cases was sufficient for practical use.

化物、あるいはカーボンなども使用することができる。In Examples 1 to 4, the firing temperature was 600 to 550'C in view of the heat resistance of the substrate and electrode materials used.
For example, when using a heat-resistant substrate such as alumina, this temperature can be raised to the heat-resistant temperature of the substrate. Regarding the compounds to be used, any inorganic acid salts such as nitrates and sulfates, organic acid salts such as acetates, complex salts, metal alkoxides, etc., which can be dissolved in an appropriate solvent, can be used without any problem. Further, as the electrode material, metals other than those used in this embodiment such as copper, aluminum, and zinc, conductive oxides such as cadmium stannate and antimony-doped tin oxide, or carbon can also be used.

大きい。Effects of the Invention As described above, the nonlinear resistance element of the present invention consists of a thin film of a mixture of manganese oxide and tin oxide and an electrode for taking electrical leads from the thin film of a mixture of manganese oxide and tin oxide. By applying a solution of a compound dissolved in a solvent onto a substrate, drying it, and then baking it in the atmosphere, it is possible to provide a nonlinear resistance element with switching characteristics at a high productivity and at a low cost. Its practical usefulness is great in that it can be easily manufactured even over a large area.
