High-density hot-pressed zinc sulfide & zinc selenide (ZnS, ZnSe) (ZnS / ZnSe, CAS 1314-98-3) ceramic sputtering targets in 4N5 (99.995%) / 5N CVD Optical Grade purity, indium-bonded for arc-free RF and pulsed-DC thin-film deposition.
Sintered by vacuum hot-pressing or Hot Isostatic Pressing (HIP) from sub-micron 4N5 (99.995%) / 5N CVD Optical Grade precursor powders, our zinc sulfide & zinc selenide (ZnS, ZnSe) (ZnS / ZnSe, CAS 1314-98-3) sputtering targets achieve high relative density (typically 96%–99.5% of 4.05–5.26 g/cm³ theoretical density) and homogeneous phase stoichiometry. High density suppresses outgassing, surface nodule formation, and plasma arcing during RF magnetron or reactive pulsed-DC sputtering.
Hot-pressed and CVD-grade ZnS and ZnSe targets deposit low-absorption infrared (1–14 µm) optical interference coatings and photovoltaic buffer layers. Because ceramic targets have low thermal conductivity and limited thermal-shock resistance, we strongly recommend ordering ZnS / ZnSe targets metallic-indium bonded to an OFHC copper backing plate. Each target ships vacuum-packed with its batch chemical assay and density COA.
