- the first method is a method of controlling the exposure amount of ultraviolet light to be exposed, whereby the degree of oxidation is controlled.
- This method uses, for example, a light source such as a low-pressure or high-pressure mercury lamp in air and emits ultraviolet light having a wavelength of 254 nm, 365 nm or a wavelength region centered on the ultraviolet light, and reducing the volume resistivity of the thin film.

If only two types of parts with different volume resistivity are formed, current flows only in the part with low resistance, and the part with large resistance does not function as a resistance in the circuit, but simply It may function as a conductor (insulating part). Therefore, by forming three or more types of portions each having a different volume resistivity value, it is possible to form a compressible circuit having resistance.
