Abstract
A sputtering apparatus includes a chamber for containing a feed gas. An anode is positioned inside the chamber. A cathode assembly comprising target material is positioned adjacent to an anode inside the chamber. A magnet is positioned adjacent to cathode assembly. A platen that supports a substrate is positioned adjacent to the cathode assembly. An output of the power supply is electrically connected to the cathode assembly. The power supply generates a plurality of voltage pulse trains comprising at least a first and a second voltage pulse train. The first voltage pulse train generates a first discharge from the feed gas that causes sputtering of a first layer of target material having properties that are determined by at least one of a peak amplitude, a rise time, and a duration of pulses in the first voltage pulse train. The second voltage pulse train generates a second discharge from the feed gas that causes sputtering of a second layer of target material having properties that are determined by at least one of a peak amplitude, a rise time, and a duration of pulses in the second voltage pulse train.
