METHOD AND APPARATUS FOR REMOTE PLASMA TREATMENT FOR REDUCING METAL OXIDES ON A METAL SEED LAYER
First Claim
1. A remote plasma apparatus for treating a substrate with a metal seed layer, the remote plasma apparatus comprising:
- a processing chamber;
a substrate support for holding the substrate in the processing chamber;
a remote plasma source over the substrate support;
a showerhead between the remote plasma source and the substrate support;
one or more movable members in the processing chamber configured to move the substrate to positions between the showerhead and the substrate support; and
a controller with instructions for performing the following operations;
(a) providing the substrate in the processing chamber;
(b) moving the substrate towards the substrate support via the one or more movable members;
(c) forming a remote plasma of a reducing gas species in the remote plasma source, wherein the remote plasma comprises radicals of the reducing gas species;
(d) exposing the metal seed layer of the substrate to the radicals of the reducing gas species; and
(e) exposing the substrate to a cooling gas.

Abstract
Method and apparatus for reducing metal oxide surfaces to modified metal surfaces are disclosed. By exposing a metal oxide surface to a remote plasma, the metal oxide surface on a substrate is reduced. A remote plasma apparatus can treat the metal oxide surface as well as cool, load/unload, and move the substrate within a single standalone apparatus. The remote plasma apparatus includes a processing chamber and a controller configured to provide a substrate having a metal seed layer in a processing chamber, move the substrate towards a substrate support in the processing chamber, form a remote plasma of a reducing gas species, expose a metal seed layer of the substrate to the remote plasma, and expose the substrate to a cooling gas. In some embodiments, the remote plasma apparatus is part of an electroplating apparatus.
