Patent number: 8597479Abstract: A magnetron sputtering system generates a high density plasma on a target by applying magnetic fields intersecting an electric field by using a plurality of magnets that are rotatably supported. The respective magnets are revolved and rotated so that the time variation of regions where a magnetic field (line of magnetic force) generated by the each magnet is orthogonal to an electric field is prevented from becoming monotonous. Further, the respective magnets are arranged to make the distances between the center of rotation and the center of revolution of the respective magnets different from each other, so that the regions where the magnetic field (line of magnetic force) generated by the each magnet is orthogonal to the electric field are dispersed in the radial direction of a target.Type: GrantFiled: February 8, 2005Date of Patent: December 3, 2013Assignee: Tohoku Seiki Industries, Ltd.Inventors: Keitaro Harada, Masayoshi Yokoo, Norikazu Kainuma, Yoshinobu Takano, Isao Tanikawa

Patent number: 8585873Abstract: A method of sputtering with sputtering apparatus is for depositing a layer upon a substrate. The apparatus includes a sputter target with a face exposed to the substrate and a magnetron providing a magnetic field that moves relative to the target face. The speed of movement of the field is controlled such that the uniformity of the deposition on the substrate is enhanced. A particular method includes monitoring uniformity verses speed, selecting the speed that gives the preferred uniformity and controlling the field to the selected speed. The selected speed may vary over the life of the target, with increased speeds becoming desirable as the target thins.Type: GrantFiled: October 12, 2005Date of Patent: November 19, 2013Assignee: Aviza Technology LimitedInventors: Mark Ashley Ford, Rajkumar Jakkaraju
