A system and method for conductive pillars is provided. An embodiment comprises a conductive pillar having trenches located around its outer edge. The trenches are used to channel conductive material such as solder when a conductive bump is formed onto the conductive pillar. The conductive pillar may then be electrically connected to another contact through the conductive material.

A system and method for plating a contact is provided. An embodiment comprises forming protective layers over a contact and a test pad, and then selectively removing the protective layer over the contact without removing the protective layer over the test pad. With the protective layer still on the test pad, a conductive layer may be plated onto the contact without plating it onto the test pad. After the contact has been plated, the protective layer over the contact may be removed.

A copper interconnect includes a copper layer formed in a dielectric layer, having a first portion and a second portion. A first barrier layer is formed between the first portion of the copper layer and the dielectric layer. A second barrier layer is formed at the boundary between the second portion of the copper layer and the dielectric layer. The first barrier layer is a dielectric layer, and the second barrier layer is a metal oxide layer.

A method of forming an integrated circuit structure includes forming a dielectric layer; forming an opening in the dielectric layer; performing a first deposition step to form a seed layer in a first chamber; and performing a first etch step to remove a portion of the seed layer. The method may further include performing a second deposition step to increase the thickness of the seed layer. At least one of the first etch step and the second deposition step is performed in a second chamber different from the first chamber.
