The transfer mechanisms of the plurality of transfer modules transfer a plurality of substrates sequentially and serially to the plurality of process modules, and each of the plurality of transfer modules has an aligner configured to align a substrate when transferring the substrate to the process module connected to a relevant transfer module.

A magnetron sputtering system includes a substrate mounted within a vacuum chamber. A plurality of cathode assemblies includes a first set of cathode assemblies and a second set of cathode assemblies, and is configured for reactive sputtering. Each cathode assembly includes a target comprising sputterable material and has an at least partially exposed planar sputtering surface. A target support is configured to support the target in the vacuum chamber and rotate the target relative to the vacuum chamber about a target axis. A magnetic field source includes a magnet array. A cathode assemblies controller assembly is operative to actuate the first set of cathode assemblies without actuating the second set of cathode assemblies, and to actuate the second set of cathode assemblies without actuating the first set of cathode assemblies.

A substrate is positioned on a substrate supporting upper surface of a substrate support. An arrangement of permanent magnets is positioned beneath the substrate supporting upper surface so that permanent magnets are disposed underneath the substrate. The deposition material is deposited into the recesses formed in the substrate by sputtering a sputtering material from a target of a magnetron device. While depositing the deposition material, the arrangement of permanent magnets provides a substantially uniform lateral magnetic field across the surface of the substrate which extends into a region beyond a periphery of the substrate to enhance resputtering of deposited material deposited into the recesses.

The invention provides a sputter deposition assembly that includes a sputtering chamber, a sputtering target, and a magnet assembly. The magnet assembly includes a two-part magnetic backing plate that includes first and second plate segments, of which at least one is laterally adjustable. Also provided are methods of operating the sputter deposition assembly.

Methods and apparatus for performing physical vapor deposition in a reactor chamber to form aluminum material on a substrate including: depositing a first aluminum layer atop a substrate to form a first aluminum region having a first grain size and a second aluminum layer atop the first aluminum layer, wherein the second aluminum layer has a second grain size larger than the first grain size; and depositing aluminum atop the second aluminum layer under conditions sufficient to increase the second grain size.

A method of forming a sub-structure, suitable for use as a hot seed in a perpendicular magnetic recording head, is described. A buffer layer of alumina with a thickness of 50-350 Angstroms is formed by atomic layer deposition as a write gap. Thereafter, one or more seed layers having a body-centered cubic (bcc) crystal structure may be deposited on the buffer layer. Finally, a magnetic film made of FeCo or FeNi with a coercivity of 60-110 Oe is deposited on the seed layer(s) by a physical vapor deposition (PVD) method at a rate of 0.48 to 3.6 Angstroms per second. The magnetic film is preferably annealed at 220° C. for 2 hours in a 250 Oe applied magnetic field.
