The elements of 3B, 4A and 4B may be contained in one or two or more. Here, x, y, z, s, and t, which are the ratios of the respective elements, are not particularly limited in the range in which oxides can be obtained and can be arbitrary numbers depending on the desired complex oxides, but are usually set in the range of 0.1 to 5, The molar ratio of each compound of the above general formulas (1) to (8) may be adjusted so as to obtain a composition. In this composite oxide, it is possible to prepare such an oxygen-deficient compound and the like, and other composition ratios are not limited to the integer ratios but can be prepared by adjusting the addition amount of each element.

Examples of the elements other than Zn, 3B, 4A and 4B of the present invention include alkaline metals such as Group 1A elements, alkaline earth metals such as Group 2A elements, rare earths such as lanthanoids and arctinoids, and Group 3A, 5A, 6A and 7A A composite oxide containing elements of Zn to 4B and elements other than these elements may be formed by coexisting a metal compound capable of forming an oxide such as a noble metal, a transition metal, a 5B group element, .
Particularly, the composition of the present invention is a zinc-containing compound prepared as described above, which is obtained by partial hydrolysis of an organic zinc compound represented by the following general formula (1) and an organic zinc compound such as diethyl zinc and water Products can be used. This addition is a hydrolysis of the composition in which the alkyl group R < 1 > bonded to the product obtained by partial hydrolysis of the organozinc compound and the organozinc compound with water Is confirmed by the classification, determination of hydrocarbon R 1 H to produce mainly from (wherein, R 1 is straight or branched alkyl group having a carbon number of 1 to 7).

The solution prepared by the above method can be used as it is as a coating solution for forming a composite oxide thin film. Alternatively, it may be appropriately diluted or concentrated. However, from the viewpoint that the production process can be simplified, it is preferable that the solution prepared by the above-described method is a concentration that can be used as a coating solution for forming the oxide complex oxide.
[Production method of composite oxide thin film]
A method for producing the composite oxide thin film of the present invention will be described. The method for producing a composite oxide thin film of the present invention is a method for producing a composite oxide thin film using the composite oxide thin film forming composition of the present invention. In this manufacturing method, the composition for forming a composite oxide thin film of the present invention is applied to the surface of a substrate, and then the obtained coating film is heated to obtain a composite oxide thin film.
Application to the surface of the substrate can be carried out by conventional means such as dip coating method, spin coating method, spray pyrolysis method, ink jet method, and screen printing method. When the application is carried out by, for example, a spin coating method, a dip coating method or a spray pyrolysis method, a composite oxide thin film having an average transmittance of 80% or more with respect to visible light can be formed. In other words, from the viewpoint of forming a composite oxide thin film having an average transmittance of 80% or more with respect to visible light, the coating method is preferably carried out by, for example, a spin coating method, a dip coating method, or a spray pyrolysis method.
The application of the composition to the substrate surface can be carried out under an atmosphere of inert gas such as nitrogen or the like in an air atmosphere containing a large amount of water vapor and a high relative humidity in an atmosphere of an oxidizing gas such as oxygen, Or in a mixed gas atmosphere thereof, under atmospheric pressure or under pressure.
The application of the composition to the surface of the substrate is preferably carried out in an inert gas atmosphere such as nitrogen. The pressure in the coating film forming atmosphere can be carried out under atmospheric pressure or under pressure, or under reduced pressure. In this inert gas atmosphere, a small amount of oxygen or moisture may be used as an oxygen source necessary for formation of the oxide, and a gas component containing oxygen such as oxygen or moisture may be added in an amount that does not affect the film quality of the inert gas thin film Even if it is included.
The spin coating method and the dip coating method may be carried out under an inert gas atmosphere or by mixing an inert gas and water vapor in an atmosphere having a relative humidity of 2 to 15%.
The spray pyrolysis method is a method which can be carried out while heating the substrate. Therefore, the solvent can be dried in parallel with the application, and in some cases, heating for solvent drying is unnecessary. Depending on the conditions, the reaction of the composition of the present invention to the composite oxide may be at least partially proceeded in addition to the drying. For this reason, the composite oxide thin film can be formed more easily by heating to a predetermined temperature, which is a subsequent step. The heating temperature of the substrate may be, for example, in the range of 50 to 550 占 폚.
Fig. 1 shows a spray-coating apparatus usable by spray pyrolysis. In the figure,
Spraying of the coating liquid is carried out by spraying the coating liquid so that the size of the liquid droplet is in the range of 1 to 15 mu m from the spray nozzle while the distance between the spray nozzle and the substrate is within 50 cm, Is preferable from the viewpoint of production of a composite oxide thin film.
Considering the adhesion to the substrate and the ease of evaporation of the solvent, it is preferable that the size of all liquid droplets ejected from the spray nozzle is in the range of 1 to 30 mu m. The size of the droplet is more preferably in the range of 3 to 20 mu m.
It is preferable that the distance between the spray nozzle and the substrate is within 50 cm, considering that the solvent evaporates slightly from the spray nozzle until reaching the substrate and the size of the droplet decreases. The distance between the spray nozzle and the substrate is preferably in the range of 2 to 40 cm from the viewpoint that the formation of the composite oxide thin film can be favorable.
In the spray pyrolysis method, it is preferable from the viewpoint of forming a composite oxide thin film that satisfactory film characteristics are obtained by introducing water vapor from the water
The method of introducing water vapor can be introduced into a composite oxide thin film production apparatus according to all common methods. The water vapor and the composition are preferably reacted in the vicinity of the heated substrate, and for example, an inert gas containing water vapor produced by bubbling water with an inert gas is introduced into the tube near the heated substrate.
After coating the surface of the substrate with the coating solution, the substrate is heated to a predetermined temperature as required, the solvent is dried and then heated to a predetermined temperature to form a composite oxide thin film.
The temperature at which the solvent is dried may be, for example, in the range of 20 to 200 占 폚, and may be set in a timely manner depending on the kind of coexisting organic solvent. The heating temperature for forming the complex oxide after solvent drying is, for example, in the range of 50 to 550 占 폚, preferably in the range of 50 to 500 占 폚. It is also possible to perform the solvent drying and the complex oxide formation at the same time by setting the solvent drying temperature to the same heating temperature for forming the complex oxide thereafter.
If necessary, the heating is carried out in a plasma atmosphere of hydrogen, argon, oxygen or the like in a reducing gas atmosphere such as hydrogen under an oxidizing gas atmosphere such as oxygen to promote the formation of zinc oxide, It is also possible to improve. The thickness of the composite oxide thin film is not particularly limited, but it is preferably in the range of 0.05 to 2 탆 in practical use. According to the above manufacturing method, in the case other than the spray pyrolysis method, the coating (drying) heating is repeated one or more times, so that a thin film having the film thickness within the above range can be suitably manufactured.
The composite oxide thin film formed by the above production method varies depending on the application method and subsequent drying conditions and heating conditions. The volume resistivity is a resistance per unit volume, which can be obtained by multiplying the surface resistance by the film thickness. The surface resistance is measured by, for example, the 4-probe method, and the film thickness is measured by, for example, SEM measurement, a stylus type step film thickness meter or the like. Since the volume resistivity changes (increases) by the degree of formation of the composite oxide upon application of the spray or after coating, the volume resistivity is preferably controlled so that the volume resistivity of the thin film becomes a desired resistance value, Time) is preferably set.
The composite oxide thin film formed by the above production method preferably has an average transmittance of 80% or more with respect to visible light, more preferably an average transmittance of 85% or more with respect to visible light. The " average transmittance to visible light " is defined and measured as follows. The average transmittance to visible light is the average of the transmittance of light in the range of 380 to 780 nm and is measured by an ultraviolet visible spectrophotometer. The average transmittance to visible light can also be expressed by showing the transmittance of visible light at 550 nm. Since the transmittance to visible light is changed (increased) by the degree of formation of zinc oxide upon application of the spray or after coating, the transmittance of the thin film to visible light is preferably 80% or more, It is desirable to set the heating conditions (temperature and time).
The substrate used may be, for example, an alkali glass, an alkali-free glass, or a transparent substrate film, and the transparent substrate film may be a plastic film. However, the present invention is not intended to be limited to these examples.
[Use of composite oxide thin film]
The composite oxide thin film produced by the above method has excellent transparency and mobility, and thus can be used as an antistatic film, an ultraviolet ray cut film, a transparent conductive film, and the like. The antistatic film can be used, for example, in fields such as solid electric field capacitors, chemically amplified resistors, construction materials such as glass windows, and the like. The ultraviolet cut film can be used, for example, in fields such as a front filter of an image display apparatus, an imaging apparatus such as a drive recorder, a lighting apparatus such as a high-pressure discharge lamp, a cover glass for a clock, Further, the transparent conductive film may be formed of a material such as an FPD, a resistive film touch panel, a capacitive touch panel, a thin film silicon solar cell, a compound (CdTe, CIS) thin film solar cell, It is available in the field.
Particularly, the composite oxide such as ZTO or ATO is an oxide semiconductor film made of them and is characterized in that it has higher mobility than an amorphous Si film together with an oxide semiconductor film made of oxide (IGZO) of In, Ga and Zn, (Thin film transistor) such as an electroluminescent display device and the like. Such a field effect transistor such as a thin film transistor (TFT) is widely used as a unit electronic element, a high frequency signal amplifying element, a liquid crystal driving element, and the like of a semiconductor memory integrated circuit, and is an electronic device which is most practically used at present. However, it is not intended to be limited to these fields.
