ITO target material is a composite material made by mixing indium oxide (In₂O₃) and tin oxide (SnO₂) in a specific ratio. This special combination gives ITO target material unique physical and chemical properties, achieving high transparency and low resistance in the thin film through precise component ratio.

ITO has excellent optical transparency (with a transmittance of over 85% in the visible light spectrum) and excellent electrical conductivity (resistivity typically around 10⁻⁴ Ω·cm), making it the preferred transparent electrode material in modern electronic devices. It is a a key material in display technology, solar cells, and smart electronic devices.

With the help of nanometer-level thin film deposition technology, ITO not only enhances the interactive experience of smart devices but also continually expands its possibilities in high-performance optoelectronic applications.
