膜を形成する方法がある。Conventional wet ferrite film manufacturing methods include, for example, as disclosed in Japanese Patent Application Laid-Open No. 59-111929, in which a water bath solution containing at least ferrous ions as metal ions is brought into contact with a solid surface. Then, FaOH+ or other hydroxide metal ions are adsorbed onto the solid surface, and then the adsorbed FeOH is oxidized to obtain FeOH, which undergoes a ferrite crystallization reaction with the hydroxide metal ions in the water bath liquid. There is a method in which a ferrite film is formed on the solid surface.

るという特徴がある。Based on this technology, we aim to homogenize the plating film or improve the reaction rate by eliminating the reaction in the aqueous solution as much as possible (Japanese Unexamined Patent Publication No. 140713/1983), and impart surface activity to the solid surface. (Japanese Unexamined Patent Publication No. 61-30674), or those related to improving the rate of ferrite production (Japanese Unexamined Patent Publications No. 179877/1983 or 1983-1983). 2229
Publication No. 24). (In the present invention, all of these methods are collectively referred to as ferrite plating.) Ferrite plating may be any method as long as the solid on which the film is to be formed is resistant to the above-mentioned aqueous solution.
Since the reaction is carried out through an aqueous solution, it is characterized in that a spinel-type ferrite film can be produced at a relatively low temperature (below the boiling point of the aqueous solution).
そのため、他のフェライト膜作製技術に比べて、固体の
限定範囲が小さい。Therefore, compared to other ferrite film manufacturing techniques, the limited range of solids is small.

Both methods were inadequate. In other words, sufficient magnetic properties as a spinel type ferrite, especially soft properties, are not obtained. Therefore, there have been major issues regarding its application to various electronic components, etc.

This method involves depositing a ferrite film on the surface of a substrate by bringing it into contact with the substrate in a neutral atmosphere.

る。Effect: By the method described above, that is, in ferrite plating, at least ferrous ions and ferrous ions are added as metal ions.
In addition to an oxidizing agent for oxidizing iron ions, a liquid containing at least sugars is brought into contact with the substrate in a non-oxidizing atmosphere to deposit a ferrite film on the surface of the substrate. It is possible to form a ferrite film with soft magnetic properties (low coercive force, high magnetic permeability) that are not found anywhere else in the world.
実施例 以下、本発明の実施例について説明する。Example Examples of the present invention will be described below.
本発明のフェライトメツキ膜の形成方法の基本的な部分

詳細原因はまったく不明である。However, in the present invention, a saccharide-containing liquid is supplied to the substrate during the ferrite plating reaction, so a ferrite film with a relatively small coercive force (high magnetic permeability) can be obtained compared to conventional methods. Unrecognized phenomenon (
(softening of the membrane). At present, the detailed cause is completely unknown.

思われる。From the results, sugars and 1v carbohydrates are general
2yoy, but by dispersing and incorporating these carbohydrates into the ferrite-plated film, the internal strain or stress of the film is relaxed compared to a ferrite-plated film that does not contain any sugars, resulting in softer magnetic properties (lower retention). It is thought that this may contribute to the magnetic force (or high magnetic permeability).

り、非酸化性雰囲気にする。Since a liquid containing at least ferrous ions as metal ions, an oxidizing agent for oxidizing the ferrous ions, and at least saccharides is used, the liquid should be at least 2.0 mol of iron to prevent oxidation of ferrous ions as much as possible until the plating reaction. It needs to be separated and prepared. Therefore, the figure shows the case where the liquid is separated into two liquids. 1 and 2 are nozzles for supplying plating liquid to the substrate 3. By selecting an appropriate nozzle 1 or 2, the liquid can be supplied in drops or in the form of a spray. 5 and 6 are tanks for storing the separated plating liquid. Further, as shown in the figure, the parts where the ferrite plating reaction is performed, such as the substrate 3 and the rotary table 4, are partitioned off by a case to create a non-oxidizing atmosphere.
