The chemical purity is crucial to a utra high-purity metal, if the purity is higher, the films you obtained possess an more outstanding level of electrical conductivity and minimized particle formation during the PVD process. Below form is a
typically Certificate of analysis for 4N high purity Zinc sputtering target.
Analytical Methods:
1. metallic elements were analyzed using GDMS.
2. Gas elements were analyzed using LECO.
