欠点がある。 Methods for forming such transparent electrodes include vacuum evaporation, in which a metal oxide is directly coated on a substrate to form a film, and a transparent electrode forming liquid containing an organometallic compound is applied to a substrate and baked to form a film. Screen printing methods, dipping methods, and the like are known. However, the vacuum evaporation method requires special equipment and is a batch method, which has disadvantages that make it unsuitable for mass production. On the other hand, the screen printing method and dipping method do not require relatively large-scale equipment and are suitable for mass production, but have the disadvantage that it is difficult to obtain uniform film thickness and film quality.

In the next firing step, the organic components become more flammable and the film quality can be made uniform. In addition, by irradiating near-infrared rays and performing baking, it is possible to directly heat the substrate by radiation or by radiation method, so the heating rate can be increased.

In order to adjust the boiling point, a trace amount of a low boiling point solvent may be added in the case of a screen printing paste, or a trace amount of a high boiling point solvent may be added in the case of a dipping liquid.

る効果が乏しくなる。 Finally, near-infrared rays are irradiated onto the substrate, preferably
Firing is carried out at a temperature of 400-600°C. Here, near-infrared rays are infrared rays that are close to visible light, and have a wavelength of 0.8μ.
It refers to something about 2.5μ. The substrate is directly heated by radiation or radiation by infrared irradiation,
The heating rate (the time it takes for the substrate surface temperature to reach 500°C from 100°C) is shortened. This prevents the volatilization of the solvent and organic binder components,
Thermal decomposition of organometallic compounds proceeds almost simultaneously,
The film quality and thickness are further made uniform. Preferably, the heating rate is adjusted between 0.5 and 3 minutes. If the heating rate is less than 0.5 minutes, there is a risk that the substrate will break if a substrate such as glass is used, and if it exceeds 3 minutes, the effect of making the thickness of the transparent electrode uniform will be poor.

Try to do it in a 9:1 gas. in this case
To set N 2 :O 2 =9:1, since air contains 80% N2 , the ratio of air:nitrogen may be set to 1:1. In this way, by changing the oxygen content between the first half and the second half of the firing process, it is possible to control the oxidation of the organic metal and form a low-resistance transparent electrode.
