  • Publication number: 20080014747
    Abstract: A method of fabricating multilayer interconnect structures on a semiconductor wafer begins by roughening the interior surface of a metal lid to a surface roughness in excess of SA 2000 with a reentrant surface profile, and installing the metal lid as the ceiling of a plasma clean reactor chamber having a wafer pedestal facing the interior surface of the ceiling. Conductive vias are formed in a dielectric layer of the semiconductor wafer, which are then covered with an overlying dielectric layer. High aspect ratio openings are etched through the overlying dielectric layer to the conductive via to expose a face of the conductive via. This step is followed by a preclean step for removing residue from the exposed face of each conductive via while capturing at least a portion of the residue on the roughened interior surface of the lid.
