ST6553 Erbium Planar Target

Erbium Planar Target Description

Stanford Advanced Materials (SAM) offers Erbium Planar Targets that are made from Erbium metal with a purity of 99.9% to 99.99% (3N-4N), making them suitable for high-performance thin film applications. These targets are available in standard diameters ranging from 50 mm to 200 mm and thicknesses of 3-10 mm, and can be customised with bonded configurations (e.g., Copper or Molybdenum backing plates) to improve thermal stability in high-performance sputtering systems. The microstructure has been developed with a fine grain size of <50 µm and a density exceeding 95% of the theoretical value, which ensures minimal particle formation and uniform layer distribution. To reduce oxidation, each target is vacuum-sealed in packaging filled with Argon and desiccant to maintain surface integrity during storage and shipping. Quality assurance protocols include ICP-MS contamination analyses, crystallographic XRD examinations, and surface roughness measurements (<0.5 µm Ra), in accordance with ASTM F3091 and ISO 9001 standards. SAM assists its clients with technical advice on sputtering parameters (e.g., optimisation of RF power, Argon gas pressure ranges) and delivers orders worldwide within 3-4 weeks for standard specifications.
