摘要： Apparatus for depositing a film of material on a substrate may comprise sputter deposition apparatus for transferring target atoms from a target to the substrate and a servo control circuit operatively associated with the sputter deposition apparatus. The servo control circuit operates the sputter deposition apparatus in an alternating manner between an "active" state and a "quiescent" state so that a power density on the target during the "active" state is at least about 400 watts per square inch of target area. During the active state, target atoms are transferred from the target to the substrate. During the quiescent state, substantially no target atoms are transferred from the target to the substrate. A polarity reversing circuit operatively associated with the servo control circuit periodically reverses a polarity on the sputter deposition apparatus during the "active" state.

摘要： A polarity reversing circuit having energy compensation may comprise a first inductor connected between the first electrode and a negative terminal of a power supply. The positive terminal of the power supply is connected to the second electrode. A diode and a first capacitor are connected in series across the first inductor so that the cathode of the diode is connected to the first electrode. A second capacitor and a switching device are also connected in series across the first and second electrodes. A second inductor is connected between the switching device and the anode of the diode. A bi-directional converter is connected between the power supply and the second capacitor. The voltage polarity between the first and second electrodes may be reversed by actuating the switching device to switch between a non-conducting state and a conducting state. The voltage polarity may be returned to the normal polarity by again actuating the switching device to switch it from the conducting state to the non-conducting state. A bi-directional converter transfers electrical energy between the polarity reversing circuit and the power supply to compensate for variations in the amount of energy reflected by the electrodes during operation.

摘要： A sputtering magnet assembly generates a magnetic field having sufficient strength to produce a plasma-confining magnetic tunnel over the front surface of a magnetic target. A magnetic shunt positioned a spaced distance from the back surface of the magnetic target provides an alternate path for excess magnetic flux liberated by erosion of the target. The alternate path provided by the magnetic shunt has a lower magnetic resistance than most paths that exit the front surface of the target, pass into the sputtering region, and re-enter the front surface of the target. Accordingly, most of the excess magnetic flux is prevented from escaping into the sputtering region.

摘要： A sputtering magnet assembly includes a plate-shaped pole piece made from a magnetically permeable material and a central magnet positioned substantially at the center of the pole piece and oriented so that its north-south magnetic orientation is substantially perpendicular to the plate shaped pole piece. A plurality of outer magnets are positioned around the central magnet, each of which has its north-south magnetic orientation also perpendicular to the pole piece, but opposite of the orientation of the central magnet. A plurality of primary inner magnets are arranged around the central magnet, between the central magnet and the outer magnets, each of which primary inner magnets has its north-south magnetic orientation parallel to the base pole piece and perpendicular to the magnetic orientations of the central magnet and the outer magnets. The resulting sputtering magnet assembly produces a magnetic field having magnetic flux lines that define a sputtering region adjacent the front surface of the target and within the target body. The magnetic flux lines form an upper magnetic lobe, a lower magnetic lobe, an inner magnetic lobe, and an outer magnetic lobe, all of which are located substantially within the sputtering region. Further, the strengths and orientations of the magnetic lobes are such that a null point exists between the upper, lower, inner, and outer magnetic lobes.
