Patent number: 7850828Abstract: The apparatus and method involve using a gas manifold for introducing gas into a deposition chamber. Certain embodiments involve using a binary manifold for uniform distribution of the gas with good response time. During sputtering operations, provision of an anode using the gas manifold enables such anode to be entirely protected from sputtered dielectric material during the deposition process. As such, conduction paths are initially established and maintained between electrons within the chamber and the anode. This results in improved maintenance of stable plasma and consistent coating in the deposition chamber. The conduction paths are enhanced in comparison to conventional systems due to increased collisions between the electrons and gas flowing out of the manifold outlets. Also, ionization of the gas flowing from the manifold outlets is enhanced, resulting in enhanced deposition output from the system.Type: GrantFiled: September 15, 2006Date of Patent: December 14, 2010Assignee: Cardinal CG CompanyInventor: John German

Patent number: 7670469Abstract: In recent years, copper wiring has emerged as a promising substitute for the aluminum wiring in integrated circuits, because copper offers lower electrical resistance and better reliability at smaller dimensions than aluminum. However, use of copper typically requires forming a diffusion barrier to prevent contamination of other parts of an integrated circuit and forming a seed layer to facilitate copper plating steps. Unfortunately, conventional methods of forming the diffusion barriers and seed layers require use of separate wafer-processing chambers, giving rise to transport delays and the introduction of defect-causing particles. Accordingly, the inventors devised unique wafer-processing chambers and methods of forming barrier and seed layers.Type: GrantFiled: September 26, 2007Date of Patent: March 2, 2010Assignee: Micron Technology, Inc.Inventors: Kie Y.

Publication number: 20090301864Abstract: The present invention has been achieved to provide a method and apparatus for speedily and homogeneously fabricating polycrystalline silicon films or similar devices at low cost. A silicon target is attached to a water-cooled electrode, while a substrate made of a desired material is set on the other, heated electrode. When atmospheric pressure hydrogen plasma is generated between the two electrodes, silicon atoms will be released from the low-temperature target on the side and deposited on the high-temperature substrate. A doped silicon film can be created by using a target containing a doping element. Since there is no need to handle expensive and harmful gases (e.g. SiH4, B2H6 and PH3), the apparatus can be installed and operated at lower costs. In an application of the film producing method according to the present invention, an objective substance can be selectively purified from a target containing a plurality of substances.Type: ApplicationFiled: September 8, 2006Publication date: December 10, 2009Applicant: SHARP KABUSHIKI KAISHAInventors: Hiromasa Ohmi, Kiyoshi Yasutake, Hiroaki Kakiuchi

Publication number: 20090229971Abstract: This application discloses a thin-film deposition apparatus comprising a vacuum chamber and a partition separating the inside of the vacuum chamber into two areas. A substrate is capable of passing through an inside opening provided in the partition. The inside opening is closed by a valve. A thin film is deposited onto the substrate in the first area. The substrate is heated by a heater in the second area prior to the deposition. The substrate is held by a holder in point contact while heated. A boosting-gas is introduced into the second area during the heating, thereby increasing pressure up to a viscous flow range. A pumping line evacuates the first area at a vacuum pressure all the time. The pumping line also evacuates the introduced boosting-gas from the second area to make the second area at a vacuum pressure when the valve is opened.Type: ApplicationFiled: April 10, 2009Publication date: September 17, 2009Applicant: CANON ANELVA CORPORATIONInventor: Masahito Ishihara

Patent number: 7588668Abstract: A sputtering target assembly and method for bonding a sputtering target to a backing plate is disclosed. When insulatively bonding a sputtering target to a backing plate, it is necessary to ensure that the bonding material has good thermal conductivity so that the temperature of the target can be effectively controlled. It is also important to not have electrical conductivity through the bonding materials. In order to achieve both goals, it is beneficial to utilize an elastomer with diamond powder filler. Diamond power has very good thermal conductivity, and it also has very good dielectric strength. Diamond is a thermally effective and cost effective substitute for silver in insulative bonding.Type: GrantFiled: March 3, 2006Date of Patent: September 15, 2009Assignee: Applied Materials, Inc.Inventors: Yan Ye, John M.
