  • Patent number: 8551267
    Abstract: Aluminum or aluminum alloy sputter targets and methods of making same are provided. The pure aluminum or aluminum alloy is mechanically worked to produce a circular blank, and then the blank is given a recrystallization anneal to achieve desirable grain size and crystallographic texture. A 10-50% additional strain is provided to the blank step after the annealing to increase the mechanical strength. Further, in a flange area of the target, the strain is greater than in the other target areas with the strain in the flange area being imparted at a rate of about 20-60% strain. The blank is then finished to form a sputtering target with desirable crystallographic texture and adequate mechanical strength.

  • Patent number: 8506771
    Abstract: A bipolar pulsed power supply which supplies power in a bipolar pulsed mode at a predetermined frequency to a pair of electrodes that come into contact with a plasma is arranged to reduce the switching loss of the switching elements in a bridge circuit, and also to attain a high durability without using high-performance switching elements. The bipolar pulsed power supply has: a bridge circuit constituted by switching elements SW1 through SW4 connected to positive and negative DC outputs from a DC power supply source; and a control means for controlling switching ON or OFF of each of the switching elements in the bridge circuit. An output-short-circuiting switching element SW0 is disposed between the positive and the negative DC outputs from the DC power supply source such that, in a short-circuited state of the output-short-circuiting switching element, each of the switching elements in the bridge circuit is switched by the control means.

  • Patent number: 8500976
    Abstract: A sputtering magnetron (300) insertable in a rotatable target is described. The magnetron is designed around a single piece, multiwalled tube (102, 202) with compartments (316, 316?, 318, 318?) extending over the length of the tube. The multiwalled tube gives a much stiffer magnetron carrier structure compared to prior art magnetrons. As a result, the magnetic field generator can be mounted inside a compartment and the distance between magnets and target surface is easily adjustable as the tube is much stiffer than the generator. Additionally, the coolant channels can be incorporated inside the tube and close to the outer wall of the tube so that coolant can be supplied in the vicinity of the magnetic field generator. The increased stiffness of the magnetron allows the target tube to be carried by the magnetron—not the other way around—at least during part of the useful life of the target.

  • Patent number: 8500963
    Abstract: A plasma sputtering method for metal chalcogenides, such as germanium antimony telluride (GST), useful in forming phase-change memories. The substrate is held at a selected temperature at which the material deposits in either an amorphous or crystalline form. GST has a low-temperature amorphous range and a high-temperature crystalline range separated by a transition band of 105-120° C. Bipolar pulsed sputtering with less than 50% positive pulses of less than 10:s pulse width cleans the target while maintain the sputtering plasma. The temperature of chamber shields is maintained at a temperature favoring crystalline deposition or they may be coated with arc-spray aluminum or with crystallographically aligned copper or aluminum.

  • Patent number: 8480865
    Abstract: The present invention relates to a magnetron sputtering device including a large ring cathode having a defined inner radius. The position of the ring cathode is offset in relation to a center point of a planetary drive system. An anode or reactive gas source may be located within the inner radius of the ring cathode. Lower defect rates are obtained through the lower power density at the cathode which suppresses arcing, while runoff is minimized by the cathode to planet geometry without the use of a mask.

    Abstract: Deposition processes and devices for the fabrication of multilayer systems to better control the energy contribution at different stages of the deposition. This is achieved by depositing films by sputtering in a scheme providing for thermalized particles. Thermalized particles are obtained by choosing the working gas pressure and the distance between target and substrate to result in a mean free path of particles smaller than the distance between target and substrate or to result in a product of pressure and distance being larger than 2.0 cmPa.
