Introduction
Iridium sputtering targets are premium precious-metal materials used for advanced thin-film deposition where extreme chemical stability, high melting point, and excellent electrical performance are required. As one of the most corrosion-resistant metals known, Iridium (Ir) is widely applied in microelectronics, catalysis, optics, and harsh-environment coatings, making it an essential material for both research and high-end industrial processes.
Detailed Description
Iridium is a platinum-group metal characterized by its exceptionally high melting point (~2446 °C), outstanding oxidation resistance, and remarkable chemical inertness. These properties allow iridium thin films to maintain structural and electrical stability even under aggressive sputtering conditions or elevated operating temperatures.
Our Iridium sputtering targets are manufactured from high-purity iridium using precision melting, forging, and machining processes to achieve dense microstructures and consistent composition. The targets exhibit excellent mechanical integrity and low impurity levels, ensuring stable sputtering rates and reproducible film properties.
Iridium targets are compatible with DC magnetron sputtering and RF sputtering systems, depending on system configuration. Planar disc targets are available in standard diameters, with optional bonding to copper backing plates to improve heat dissipation and minimize thermal stress during high-power operation. Custom sizes, thicknesses, and bonding solutions are available to meet specific equipment and application requirements.

Iridium sputtering targets are commonly used in demanding thin-film applications, including:
Microelectronics and semiconductor devices
Electrode layers for ferroelectric and capacitor structures
Hard, wear-resistant and corrosion-resistant coatings
Optical and reflective coatings
Catalytic and electrochemical thin films
