Patent number: 8206562Abstract: The invention relates to a method and apparatus for the application of material to form a layer of an organic electroluminescent device. The material is sputter deposited typically from at least one target of material held in respect to a magnetron in a coating chamber. The magnetrons used can be unbalanced magnetrons and/or are provided with other magnetrons and/or magnet arrays in a closed field configuration. The material is found to be deposited in a manner which prevents or minimises damage to the device and hence reduces or removes the need for a barrier layer to be applied.Type: GrantFiled: February 16, 2006Date of Patent: June 26, 2012Assignees: Cambridge Display Technology Limited, System Control Technologies LimitedInventors: John Michael Walls, Desmond Gibson, William Young, Nalinkumar Patel, Nicoletta Anathassopoulou

Publication number: 20120152726Abstract: A deposition system is provided, where conductive targets of similar composition are situated opposing each other. The system is aligned parallel with a substrate, which is located outside the resulting plasma that is largely confined between the two cathodes. A “plasma cage” is formed wherein the carbon atoms collide with accelerating electrons and get highly ionized. The electrons are trapped inside the plasma cage, while the ionized carbon atoms are deposited on the surface of the substrate. Since the electrons are confined to the plasma cage, no substrate damage or heating occurs. Additionally, argon atoms, which are used to ignite and sustain the plasma and to sputter carbon atoms from the target, do not reach the substrate, so as to avoid damaging the substrate.Type: ApplicationFiled: April 26, 2011Publication date: June 21, 2012Inventors: Samuel D.

Publication number: 20120118725Abstract: A film forming method of forming a coating on a surface of an object to be processed includes disposing a target forming a base material of the coating and the object to be processed in a chamber so as to face each other, and generating a magnetic field through which a vertical line of magnetic force locally passes from a sputter surface of the target toward a surface to be film formed of the object to be processed at predetermined intervals; generating plasma in a space between the target and the object to be processed by introducing a sputter gas into the chamber, controlling a gas pressure in the chamber to a range of 0.3 Pa to 10.0 Pa, and applying a negative DC voltage to the target; and inducing and depositing the sputter particles on the object to be processed and forming the coating, while controlling flying direction of the sputter particles generated by sputtering the target.Type: ApplicationFiled: May 20, 2010Publication date: May 17, 2012Applicant: ULVAC, INC.Inventors: Naoki Morimoto, Junichi Hamaguchi, Kazumasa Horita, Naoki Takeda
