    摘要: 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.

    摘要: 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.
