High-purity europium metal is melted in a vacuum induction furnace. This process ensures the europium sputtering target material maintains uniform composition and minimizes oxidation—critical for achieving stable sputtering performance.
The solidified europium ingot is carefully shaped by sawing or turning to remove surface oxides and impurities. This step prepares the ingot for further forming, ensuring the europium sputtering target has clean, defect-free raw material.
Through controlled hot forging or rolling, the europium ingot undergoes deformation to increase density and refine the grain structure. This step enhances the mechanical strength and uniformity required for high-efficiency europium sputtering targets.
The forged europium material is annealed in a high-vacuum furnace to eliminate internal stress caused by hot working. This heat treatment stabilizes the europium target's crystal structure, ensuring consistent sputtering erosion and long service life.
Using advanced CNC equipment, the annealed europium blank is precisely machined into the desired target form—circular, rectangular, or custom. This guarantees exact dimensional accuracy and perfect compatibility with different sputtering systems.
The europium sputtering target surface is ground and polished to achieve exceptional flatness and smoothness. This ensures excellent target-to-substrate contact, uniform film deposition, and reduced arcing during sputtering.
Each europium sputtering target undergoes strict testing for density, dimensional accuracy, and surface quality. After passing all inspections, it is vacuum-sealed and packaged in moisture-proof, contamination-free containers for safe global shipment.
