    摘要: A PVD system comprises a hollow cathode magnetron with a downstream plasma control mechanism. The magnetron has a hollow cathode with a non-planar target and at least one electromagnetic coil to generate and maintain a plasma within the cathode. The magnetron also has an anode located between the cathode and a downstream plasma control mechanism. The control mechanism comprises a first, second and third electromagnetic coil beneath a mouth of the target, vertically spaced so as to form a tapered magnetic convergent lens between the target mouth and a pedestal of the magnetron.

    摘要: A PVD system comprises a hollow cathode magnetron with a capability of producing a high magnetic field for PVD and a low magnetic field for pasting. The high magnetic field is used for PVD and causes an optimal uniform film to form on a substrate but redeposits some metals onto a top portion of a target within the magnetron. The low magnetic field erodes redeposited materials from a top portion of a target within the magnetron.

    摘要: Methods of depositing thin seed layers that improve continuity of the seed layer as well as adhesion to the barrier layer are provided. According to various embodiments, the methods involve performing an etchback operation in the seed deposition chamber prior to depositing the seed layer. The etch step removes barrier layer overhang and/or oxide that has formed on the barrier layer. It some embodiments, a small deposition flux of seed atoms accompanies the sputter etch flux of argon ions, embedding metal atoms into the barrier layer. The embedded metal atoms create nucleation sites for subsequent seed layer deposition, thereby promoting continuous seed layer film growth, film stability and improved seed layer-barrier layer adhesion.
