The purpose is to

は厳しく要求されている。 In recent years, polymer thin films have been required and used in various electronic components such as insulating films for semiconductor devices and alignment films for liquid crystal display devices. Generally, these thin films are used with a thickness of 100 Å to 3000 Å, but uniformity of the film thickness and precision of the shape and size of the pattern are strictly required.

展色を行うことができないからである。 Conventionally, a printing method has been considered as a method for forming the thin film (for example, Japanese Patent Application Laid-Open No. 1983-1999)
(See Publication No. 37314). This method uses an offset proofing machine used in lithographic offset printing to print a polymer solution as a printing ink onto a substrate with a smooth surface such as a glass plate using a blanket cylinder equipped with a relief plate, and then prints a thin polymer film. This is a printing method.
This method has the following drawbacks. That is,
The polymer solution used for this purpose has a viscosity of
Since the solution has a very low viscosity of 2000 cp to 10 cp, it is difficult to obtain a sufficiently uniform film thickness when printing using an offset proofing machine. Furthermore, it has been difficult to stably print a thin film of desired thickness. This is because offset proofing machines use a roll kneading method to knead and spread the ink, but compared to general offset printing inks, a polymer solution with a much lower viscosity and less stickiness is used, so the ink can be printed evenly. In addition, the ink flows out from the gap between the rolls, making it impossible to spread the color uniformly. Furthermore, it is difficult to constantly and quantitatively supply ink to the rolls, and therefore it is not possible to perform quantitatively stable color development.

The ink used is of low viscosity, with a viscosity of 2000 cp to 10 cp. Usable resins or resin precursors include polyamic acid, phenol, novolak, polyester, epoxy, urethane, silicone, melamine resin or resin precursor, polyvinyl chloride, polyvinyl acetate, polymethyl methacrylate, polystyrene, polyvinyl alcohol. , thermoplastic resins such as polyvinyl butyral, polyimide, polysulfone, natural rubber, styrene-butadiene rubber, polyisobutylene, and nitrile rubber.

宜選択する。 The intaglio plate 2 used has a large number of small holes 1 in a desired pattern on its surface (see FIG. 1). This group of small holes is called a cell in the printing industry, and the shape of each of the holes may be an inverted pyramid shape, etc., and the arrangement type may be a lattice shape, a diagonal shape, etc., and the shape is appropriately selected.

従つて前記各範囲の小孔が形成された凹版を用い
ると均一な厚さの薄膜を形成できる。 The depth of small hole 1 is 3 μm to 50 μm, the average diameter of the opening is 10 μm to 500 μm, and the opening area is 5% to 80%.
Total recess volume per cm 2 is 0.05mm 3 ~ 5mm 3 , small hole 1
The average shortest distance between them is 10 μm to 2000 μm. This specification is made in order to form a thin film of uniform thickness. In other words, if the small holes have a value larger than each of the above ranges, the amount of ink filled in the intaglio plate is too large, and when the roller presses against the surface of the printing material, the ink protrudes around the roller, and as a result, the printing material The thickness of the thin film formed on the surface is not constant. In addition, if the small holes are smaller than the above range, the amount of ink filled and transferred is too small, and the ink transferred from each small hole tends to be transferred independently to the surface of the printing material. Therefore, it is not possible to form a continuous thin film of uniform thickness.
Therefore, by using an intaglio plate in which small holes are formed in each of the above ranges, a thin film of uniform thickness can be formed.

The thickness of the thin film to be formed can be adjusted by selecting and using an intaglio plate 2 in which the total concave volume of the small holes 1 and the average shortest distance between the small holes 1 are set appropriately. In addition, when filling ink into the intaglio 2,
A more accurate amount of ink can be applied using a doctor or the like.

離が1.0μｍ〜1000μｍである。 Incidentally, the intaglio plate 2 may be provided with a group of grooves of appropriate length instead of one group of small holes. In this case, the depth of the groove is 3 μm to 50 μm, and the average width of the opening is 1.0 μm.
~500 μm, the opening area is 5% to 80%, the total recess volume per cm 2 is 0.05 mm 3 to 5 mm 3 , and the average distance between grooves is 1.0 μm to 1000 μm.

Thereafter, the roller 4 is brought into pressure contact with the dry offset plate 5 on which a pattern has been provided in advance. Due to this pressure contact, the ink 3 is transferred only to the pattern portion of the dry offset plate 5 (see FIG. 3).
Next, the blanket roller 6 and the surface of the dry offset plate 5 are brought into pressure contact, and the ink 3 on the pattern portion is transferred to the surface of the blanket roller 6 (see FIG. 4). Thereafter, the blanket roller 6 is applied to form a thin film 8 on the surface of a printing medium 7 such as a glass plate (see FIG. 5).

る。 Since the present invention is a thin film printing method as described above, it is possible to accurately and stably fill an intaglio plate with ink even if it is a low viscosity ink, so it is easy to form a thin film with a uniform thickness. It is possible to form a film with an accurate film thickness in a stable manner. Further, the dimensional accuracy of the desired pattern shape can also be accurately obtained. Therefore, it is expected that it will be widely used for forming polymer thin films for various electronic components.

囲第１項記載の薄膜印刷方法。[Claims] 1. The depth is 3 μm to 50 μm, and the average diameter of the opening is 1 μm.
~500 μm, the opening area is 1% to 80%, the total concave volume of the small holes per 1 cm2 is 0.05 mm3 to 5 mm3 , and the average shortest distance between the small holes is 10 μm to 2000 μm. After filling the ink made of a resin or a resin precursor and a solvent with a viscosity of 2000 cp to 10 cp into the concave plate provided on the entire surface or in necessary parts, a roller is brought into pressure contact with the intaglio surface, and the ink is applied to the roller. The ink is transferred to the surface of the dry offset plate, and then the roller is brought into pressure contact with the surface of the dry offset plate on which a pattern has been provided in advance, and the ink is transferred to the patterned portion of the dry offset plate. 1. A thin film printing method comprising the steps of: bringing the blanket roller into pressure contact with the blanket roller to transfer the ink onto the surface of the blanket roller; and then bringing the blanket roller and the surface of the printing material into pressure contact to form a thin film on the surface of the printing material. 2. The thin film printing method according to claim 1, wherein the roller is made of butyl rubber. 3. The thin film printing method according to claim 1, wherein the roller is made of nylon resin. 4 Depth is 3 μm to 50 μm, average width of opening is 1 μm
-500 μm, opening area of 5% to 80%, total recessed volume of grooves per 1 cm2 of 0.05 mm3 to 5 mm3 , average distance between grooves of 1.0 μm to 1000 μm. 2. A thin film printing method according to claim 1, characterized in that a thin film printing method is used.
