Patent ID: 8236152

Claim:
A deposition system, comprising: a chamber comprising one or more outer chamber walls and one or more inner chamber walls, wherein the one or more outer chamber walls are positioned around a center axis, wherein the one or more inner chamber walls are positioned around the center axis, wherein the one or more outer chamber walls and the one or more inner chamber walls define a vacuum enclosure in between; a plurality of substantially planar targets mounted on the one or more inner chamber walls and in the vacuum enclosure, wherein the sputtering surfaces of the plurality of targets are positioned substantially along the sides of a first polygon around the center axis; a plurality of substantially planar backing plates each mounted on the one or more inner chamber walls and on the opposing side of one of the plurality of targets; a plurality of magnetron sources adjacent to one of the plurality of substantially planar backing plate and configured to produce a substantially uniform magnetic field near the sputtering surface on the one of the plurality of substantially planar targets; a plurality of substrates outside and surrounding the plurality of substantially planar targets in the chamber, wherein the plurality of substrates comprise deposition surfaces substantially facing toward the plurality of substantially planar targets and configured to receive materials sputtered off the sputtering surfaces; and a transport mechanism configured to move the plurality of substrates in a direction parallel to the center axis.
