Abstract

Methods for reducing inclusion content of sputter targets and targets so produced are disclosed. Inclusions may be reduced by adding a small amount of Si to the molten Al or molten Al alloy followed by filtering of the molten metals through a filter medium. Targets having substantially no inclusions therein of greater than about 400 μm are especially useful in the sputtering of large flat panel displays and result, upon sputtering, in a reduction in the amount of macroparticles sputtered onto the substrate.
