Niobium target/high-purity sputtering target
Niobium target is a high-purity niobium metal material used in physical vapor deposition (PVD) processes. It is mainly formed on substrates (such as silicon wafers, glass, tool surfaces) through techniques such as magnetron sputtering to form a uniform and dense niobium or niobium based thin film.
This thin film is widely used in semiconductor integrated circuits, superconducting cavities, flat panel displays, and functional coatings due to its excellent conductivity, low-temperature superconducting properties, good corrosion resistance, and compatibility with silicon processes. As a professional niobium target manufacturer, we are committed to providing high-performance and stable quality sputtering target solutions for high-end manufacturing industries.

Points you may be concerned about
1. Strict quality control system
We are well aware that for sputtering targets, purity and density are the key factors determining the properties of thin films.
- Raw material traceability: Strictly select high-purity niobium ingots that meet the standards (such as RO4200/RO4210) to ensure the purity of the source.
- Whole process inspection:
Purity analysis: GDMS (glow discharge mass spectrometry) is used to detect raw materials and finished products, ensuring a stable purity of over 99.95%. Key impurity elements such as Ta, W, Mo, Fe, etc. are strictly controlled.
Microstructure testing: Ensure fine and uniform grain size, without defects such as oxide inclusions, through metallographic analysis.
Non destructive testing: Use ultrasonic testing (C-Scan) to conduct a comprehensive inspection of the target blank, ensuring that there are no cracks or delamination inside.
- Complete certificates: Material certificates and factory inspection reports are provided with the goods, and third-party inspection reports can be provided upon request.
2. Unveiling advanced production technology
Our advantage stems from precise control over key processes.
- Smelting technology: Electron beam melting (EB) or vacuum consumable arc melting (VAR) technology is used to effectively remove gas impurities and volatile impurities, obtaining high-purity and uniformly composed niobium ingots.
- Plastic processing: Through precision plastic deformation processes such as forging, hot rolling, and cross rolling, the as cast microstructure is effectively broken, grain size is refined, and grain orientation is optimized, providing the best foundation for later bonding.
- Binding technology: With mature diffusion welding, brazing, and epoxy resin binding processes, it ensures high-strength and low stress metallurgical bonding between niobium target materials and backing plates (such as oxygen free copper and aluminum), excellent interface thermal conductivity and electrical conductivity, and eliminates the risk of off target of target materials under high-speed sputtering.
