摘要： A small magnet assembly having a magnet assembly of area less than 10% of the target area, is scanned in a retrograde planetary or epicyclic path about the back of a target being plasma sputtered including an orbital rotation about the center axis of the target and a planetary rotation about another axis rotating about the target center axis. The magnet assembly passes through the target center, thus allowing full target coverage. A properly chosen ratio of the two rotations about respective axes produces a much slower magnet velocity near the target periphery than at the target center. A geared planetary mechanism includes a rotating drive plate, a fixed center gear, and an idler and a follower gear rotatably supported in the drive plane supporting a cantilevered magnet assembly on the side of the drive plate facing the target.

摘要： A magnetron sputter reactor for sputtering deposition materials such as tantalum, tantalum nitride and copper, for example, and its method of use, in which self-ionized plasma (SIP) sputtering and inductively coupled plasma (ICP) sputtering are promoted, either together or alternately, in the same or different chambers. Also, bottom coverage may be thinned or eliminated by ICP resputtering in one chamber and SIP in another. SIP is promoted by a small magnetron having poles of unequal magnetic strength and a high power applied to the target during sputtering. ICP is provided by one or more RF coils which inductively couple RF energy into a plasma. The combined SIP-ICP layers can act as a liner or barrier or seed or nucleation layer for hole. In addition, an RF coil may be sputtered to provide protective material during ICP resputtering. In another chamber an array of auxiliary magnets positioned along sidewalls of a magnetron sputter reactor on a side towards the wafer from the target. The magnetron preferably is a small, strong one having a stronger outer pole of a first magnetic polarity surrounding a weaker outer pole of a second magnetic polarity and rotates about the central axis of the chamber. The auxiliary magnets preferably have the first magnetic polarity to draw the unbalanced magnetic field component toward the wafer. The auxiliary magnets may be either permanent magnets or electromagnets.

摘要： Sputtering in a physical vapor deposition (PVD) chamber may, in one embodiment, utilize a target laterally offset from and tilted with respect to the substrate. In another aspect, target power may be reduced to enhance film protection. In yet another aspect, magnetron magnets may be relatively strong and well balanced to enhance film protection. In another aspect, a shutter may be provided to protect the substrate in start up conditions. Other embodiments are described and claimed.
