Zusammenfassung:	In some embodiments, an integrated tool for opening an etch stop layer and performing metallization comprises a first chamber with a remote plasma source, a direct plasma source, and a thermal source configured to open the etch stop layer on a substrate, a second chamber of the integrated tool with dry etch processing configured to pre-clean surfaces exposed by opening the etch stop layer, a third chamber of the integrated tool configured to deposit a barrier layer on the substrate, a fourth chamber of the integrated tool configured to deposit a liner layer on the substrate, and at least one fifth chamber of the integrated tool configured to deposit metallization material on the substrate. The integrated tool may also include a vacuum transfer chamber.
