    Abstract: A rotor having a cylindrical peripheral surface is disposed in a treatment vessel into which a carrier gas is introduced, and the rotor peripheral surface is opposed to the surface of a substrate with a predetermine gap therebetween. Film-forming particulates including atomic molecules of the film-forming material and cluster particulates thereof are scattered from the surface of the film-forming material supplying member by sputtering, and the rotor is rotated to form a carrier gas flow near the rotor peripheral surface. The film-forming particulates are transported to the vicinity of the surface of the substrate by the carrier gas flow and adhered to the surface of the substrate. As a result, the adverse effect of high-energy particles and the like is suppressed to efficiently form a satisfactory thin film by an evaporation or sputtering process, which has less restriction to a source material gas, without the need for large equipment.

  • Patent number: 6949170
    Abstract: A method and apparatus for processing a thin film on a substrate. The method involves locating the substrate in a first rotational position a location opposed to a process station. The process station has a first axis and is arranged for processing the substrate about that axis. The substrate location is symmetrical about a second axis parallel to but offset from the first axis. The substrate is rotated about an axis generally orthogonal and passing through the wafer location to a second rotational position after an initial process and further processing takes place when the substrate is in the second rotational position.

  • Patent number: 6905578
    Abstract: An apparatus and method for depositing plural layers of materials on a substrate within a single vacuum chamber allows high-throughput deposition of structures such as these for GMR and MRAM application. An indexing mechanism aligns a substrate with each of plural targets according to the sequence of the layers in the structure. Each target deposits material using a static physical-vapor deposition technique. A shutter can be interposed between a target and a substrate to block the deposition process for improved deposition control. The shutter can also preclean a target or the substrate and can also be used for mechanical chopping of the deposition process. In alternative embodiments, plural substrates may be aligned sequentially with plural targets to allow simultaneous deposition of plural structures within the single vacuum chamber.

  • Patent number: 6878242
    Abstract: A rotating sputtering target(s) is segmented so as to include a plurality of different sputtering material portions or segments radially dispersed around the outer periphery of the target. This enables a plurality of different layers to be sputter-deposited, one after the other, using the same sputtering target as the target rotates. The thicknesses of the different layers can be controlled by the radially extensive size of the different segments, the rotation speed of the target, the material sputter rate, the sputtering power used, and/or the line speed of the sputter coater in which the target(s) is located. One or more such targets may be used in a coater according to different embodiments of this invention.

  • Patent number: 6858085
    Abstract: An apparatus for sequential and isolated processing of a workpiece comprises a two compartment chamber and a mechanism to transfer the workpiece from one compartment to the other compartment. The transfer mechanism comprises two doors that seal the pathway between the two compartments between movement so that the two compartments are isolated and the workpiece can be processed sequentially and isolatedly in each compartment. The apparatus further comprises components to enable the processing of a workpiece: a delivery system to delivery precursor, a plasma source to generate a plasma and a vacuum pump to maintain a sub-atmospheric pressure. The preferred method of processing a workpiece is to deposit or adsorb a thin layer in the first compartment and then to transfer the workpiece to the second compartment for a reaction or a plasma reaction on the existing thin layer.
