    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: Methods for forming a via structure are provided. The method includes depositing a first-layer conductive line over a semiconductor substrate, forming a dielectric layer over the first-layer conductive line, forming a via opening in the dielectric layer and exposing the first-layer conductive line in the via opening, forming a recess portion in the first-layer conductive line, and filling the via opening to form a via extending through the dielectric layer to the first-layer conductive line. The via has a substantially tapered profile and substantially extends into the recess in the first-layer conductive line.
