摘要:
Embodiments described herein generally relate to components for a semiconductor processing chamber, a process kit for a semiconductor processing chamber, and a semiconductor processing chamber having a process kit. In one embodiment a lower shield for encircling a sputtering target and a substrate support is provided. The lower shield comprises a cylindrical outer band having a first diameter dimensioned to encircle the sputtering surface of the sputtering target and the substrate support, the cylindrical band comprising a top wall that surrounds a sputtering surface of a sputtering target and a bottom wall that surrounds the substrate support, a support ledge comprising a resting surface and extending radially outward from the cylindrical outer band, a base plate extending radially inward from the bottom wall of the cylindrical band, and a cylindrical inner band coupled with the base plate and partially surrounding a peripheral edge of the substrate support.
