    Abstract: Physical vapor deposition target assemblies, PVD chambers including target assemblies and methods of manufacturing EUV mask blanks using such target assemblies are disclosed. The target assembly includes a target shield adjacent the target and surrounding the peripheral edges of the target, the target shield comprising an insulating material and a non-insulating outer peripheral fixture to secure the target shield to the assembly.
