Stanford Advanced Materials (SAM) offers precision-crafted Europium Planar Sputtering Targets, engineered for advanced thin-film deposition. Manufactured from high-purity europium (99.9%–99.99%), these targets feature >95% theoretical density and sub-50 μm grain size to ensure consistent deposition rates, minimal particulate formation, and high film integrity.
Each target is produced under strict quality controls and is fully customizable in size (up to 200 mm diameter, 3–10 mm thickness), with optional bonding to copper or other backing plates to improve heat dissipation during sputtering. Targets are packaged under inert gas in vacuum-sealed containers to minimize surface oxidation.
Quality Highlights:
Purity: 99.9% minimum
Crystallinity & Impurity Control: Verified via XRD and ICP-MS
Packaging: Vacuum-sealed in argon atmosphere
Support: Deposition guideline documentation and post-purchase technical support available
