Vacuum-melted high-purity silver (Ag, CAS 7440-22-4) planar magnetron sputtering targets in 4N (99.99%) / 4N5 (99.995%) / 5N grades for semiconductor, optical, and research PVD.
High-purity silver (Ag, CAS 7440-22-4) planar sputtering targets are consolidated by vacuum melting or hot isostatic pressing and thermomechanically processed to achieve fine, equiaxed microstructure and ≥99.5%–100% relative density. Controlled grain uniformity and ultra-low dissolved gas content (O, N, H, C) ensure stable DC, pulsed-DC, RF, and HiPIMS plasma impedance with minimal droplet or particle generation across the target erosion track.
Vacuum-melted high-purity silver targets deliver very high DC sputtering deposition rates for mirrors, Low-E glass, and plasmonic nanostructures. Each silver target is precision-machined to fit 1-inch (25.4 mm), 2-inch (50.8 mm), 3-inch (76.2 mm), 4-inch (100/101.6 mm), or custom rectangular magnetron cathodes, supplied monolithic or indium-bonded to an OFHC copper backing plate, and vacuum-sealed with a batch GDMS or ICP-OES Certificate of Analysis.
