- Drying of the film formed on the substrate can be in the range of room temperature to 150 ° C., and preferably 50 to 100 ° C. If the temperature is lower than room temperature, not only does it take much time to dry the coating film, but also in the subsequent step, when the resist is applied, mixing of the resist and the dried film occurs, and a good pattern cannot be obtained. At temperatures above 150 ° C, The solubility in the alkali developing solution becomes poor, and a residual film remains in the etching portion, so that a good pattern cannot be obtained.

- the firing atmosphere may be changed to an oxygen atmosphere, a nitrogen atmosphere, a reducing atmosphere, or the like as necessary.
- irradiating the pattern film before firing with ultraviolet rays promotes the densification of the film and has an effect of lowering the resistance. Therefore, in some cases, irradiation with ultraviolet rays may be acceptable.
- the present invention focuses on the tin oxide (IV) -based thin film patterning method, which has been difficult to etch and cannot obtain a good pattern, and discovers that the chemical resistance of the coating film is different due to the irradiation of ultraviolet rays. Since a photoresist film was not used, the process was simplified, and then firing was performed, so that a transparent conductive tin oxide pattern film was obtained simply and efficiently.
