    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 for forming an integrated circuit structure includes providing a semiconductor substrate; forming a low-k dielectric layer over the semiconductor substrate; generating hydrogen radicals using a remote plasma method; performing a first hydrogen radical treatment to the low-k dielectric layer using the hydrogen radicals; forming an opening in the low-k dielectric layer; filling the opening with a conductive material; and performing a planarization to remove excess conductive material on the low-k dielectric layer.
