Overview

Iridium sputtering targets are manufactured using iridium, a platinum group metal, as the core material. Through processes including high-purity refinement, powder metallurgy, and hot pressing, these targets play a pivotal role in thin-film fabrication. Their value lies in harnessing iridium's high melting point, exceptional chemical inertness, outstanding electrocatalytic activity, and favourable electrical properties to overcome material limitations in achieving miniaturisation, high efficiency, and extended lifespan for advanced devices. Despite iridium's scarcity and high cost, it has become a vital strategic material for modern high-tech industries. Our company can provide customers with customised Iridium Rod, Iridium Ribbon and Strip, and Platinum Iridium Wire. If you're interested, please click the link to view product details.

Application

1. Semiconductor and Microelectronics Industry

• Dynamic Random Access Memory (DRAM): Serves as electrode material for capacitors. Within high-density DRAM capacitor structures, it effectively prevents dielectric layer degradation, enhancing memory durability and data retention capability.
• Next-generation logic devices: At advanced process nodes, iridium thin films are being investigated for use as work function modifiers or diffusion barrier layers.
• Perpendicular Magnetic Recording (PMR) Hard Drives: Iridium films serve as additives or intermediate layers in magnetic recording layers, facilitating smaller magnetic domain sizes and increased storage density.

2. Optical and Optoelectronic Devices

• Iridium films exhibit high reflectivity and outstanding environmental stability, making them suitable for manufacturing high-performance mirrors, infrared optical components, and anti-reflective coatings.

3. Fuel Cells and Electrochemistry

• Hydrogen production via water electrolysis: Iridium thin film catalysts prepared by sputtering exhibit a high specific surface area and controllable thickness, finding extensive application in the anodes of proton exchange membrane (PEM) electrolyzers.
• Electrochemical sensors: Leveraging the catalytic activity and stability of iridium thin films enables the manufacture of highly sensitive, long-life gas or biosensors.

4. Corrosion-Resistant and Wear-Resistant Coatings

• In aerospace, chemical engineering, and other sectors, Iridium Sputtering Targets enable the deposition of iridium films onto critical components (e.g., nozzles, bearings), significantly enhancing their high-temperature resistance, corrosion resistance, and wear resistance.

5. Scientific Research and Specialised Applications

• Beyond fundamental studies in thin-film physics and catalytic mechanisms, it facilitates the production of specialised devices requiring extreme environmental stability, such as high-temperature thermocouples and spacecraft components.

6. Precision Medical Devices

• Radiotherapy Targets: Iridium-192 radioactive isotopes are integrated via sputtering technology onto the tip of interventional catheters, enabling localised high-dose irradiation of tumours.
• Synchrotron Radiation Systems: Iridium films (10-20nm thick) function as X-ray mirrors, achieving nanometre-scale spot focusing to support high-precision cutting-edge biomedical research.

Process

① Remove metallic impurities from the raw material using electron beam melting or chemical purification methods (such as ion exchange or solvent extraction).

② Pack iridium powder into an elastic mould and place it within a high-pressure vessel, ensuring uniform force application in all directions to compact a green compact with a density reaching 60%–70% of theoretical density.

③ High-temperature sintering facilitates complete diffusion and bonding of iridium particles within the green compact, eliminating porosity to achieve over 98% theoretical density.

④ The iridium compact is initially cut to dimensions via electrical discharge machining, followed by high-precision planar grinding and polishing on a CNC milling machine to ensure dimensional accuracy.

⑤ Comprehensive quality inspections are conducted, including purity verification, physical property assessment, dimensional checks, and sputtering performance testing, to guarantee flawless delivery.

Case

Iridium Sputtering Target, Iridium Target To Singapore

Recently, FANMETAL, a non-ferrous metal supplier with extensive years of experience, completed a customized Iridium Target order for a precision manufacturing enterprise in Singapore and formally shipped it via air freight to the same destination. To effectively address customer needs, FANMETAL established a dedicated service team at the outset of collaboration. This team engaged in multiple rounds of online communication with the client's technical team to precisely break down specifications. The production process implemented a comprehensive quality traceability system, establishing multiple inspection points from raw material intake to finished product shipment. These covered critical metrics, including purity testing, density measurement, and dimensional calibration. Concurrently, supply chain processes were optimized, reducing the custom production cycle to 25 days, effectively meeting urgent production schedules.
