Patent number: 6794278Abstract: Disclosed is a method for forming a thin-film layer, such as a metallic film or a transparent conductive film, on a functional organic layer formed from an organic compound, by means of a sputtering method performed at a low discharge voltage and a low gas pressure, without imparting any damage to the surface of the organic layer. The thin-film layer is formed by use of a facing-targets-type sputtering apparatus including a pair of facing targets disposed a predetermined distance away from each other; an electron reflection electrode disposed on the periphery of each target; and magnetic field generation means disposed at the sides of each target. The magnetic field generation means generates a magnetic field extending from one target to the other so as to surround a confinement space provided between the paired targets, as well as a magnetic field having a portion parallel to the surface of each target in the vicinity of a peripheral edge portion of the target.Type: GrantFiled: April 9, 2002Date of Patent: September 21, 2004Assignees: International Manufacturing and Engineering Services, Co., Ltd.Inventors: Junji Kido, Akira Yokoi, Sadao Kadokura
