Claim 0:
1. A method for processing a substrate in a physical vapor deposition (PVD) chamber, comprising:
selectively etching from a substrate disposed in the PVD chamber an exposed first layer of material, covering an underlying second layer of material, and adjacent to a third layer of material having a top surface exposed above an entirety of the first layer of material, using both process gas ions and metal ions formed from a target of the PVD chamber, in an amount sufficient to expose the second layer of material while simultaneously depositing a layer of metal to passivate the third layer of material to protect the third layer from breakdown during an outgassing procedure; and
subsequently depositing metal from the target onto the second layer of material.
