Indium Tin target is an alloy sputtering target made from indium (In) and tin (Sn) through metallurgical processes. It is widely used in photovoltaic, low-radiation glass, and mobile device coatings.

Core Advantages of Indium Tin Target

l ‌Optoelectronic Properties

High Electrical Conductivity: The film achieves a low resistivity of 10⁻⁴ Ω·cm, driven by the high concentration of free electrons and oxygen vacancies induced by tin doping.

 High Transparency: Visible light transmission exceeds 85%, with an optical bandgap (3.5–4.3 eV) much larger than the energy of visible light, hence, almost no absorption.

 l ‌Mechanical Strength

The cubic crystal structure provides high hardness, making it suitable for sputtering processes.

 l ‌‌Stability

Resistant to oxidation and acid-base corrosion, but brittle under high temperatures or flexible environments.

Main Applications of Indium Tin Target

l  Display Panels

Transparent Electrodes: Used for conductive layers in LCD and OLED screens, accounting for 70% of global indium consumption.

Touch Panels: Having high transparency and sensitive conductivity it is used as sensing layer for capacitive touchscreens.

l ‌Energy Sector

Used as transparent electrodes in touchscreens for smartphones, tablets, etc., to enhance the touch sensitivity and display clarity, supporting thin designs.

Smart Glass: Conductive layers for electrochromic glass to adjust the light transmission.

l Flexible Electronics

Smart Glass: Conductive layers for electrochromic glass to tune the light transmission.
