Patent number: 7968147Abstract: The present invention relates to ceramic cutting tools, such as, an aluminum oxide with zirconium oxide ceramic cutting tool with diffusion bonding enhanced layer and CVD coatings, particularly useful for machining modern metal materials. The method comprises a chemical reaction with a mixture including nitrogen and aluminum chloride introduced to form a diffusion bonding enhanced layer between the ceramic substrate and the CVD coatings. Thus formed diffusion bonding enhanced layer is highly adherent to the aluminum oxide with zirconium oxide ceramic substrate and significantly enhances the CVD coating properties, thus improving the machining performance in terms of the tool life of zirconium-based aluminum oxide with zirconium oxide ceramic cutting tools.Type: GrantFiled: March 13, 2009Date of Patent: June 28, 2011Assignee: TDY Industries, Inc.Inventors: X.

Patent number: 7964515Abstract: A method is provided for forming high dielectric constant (high-k) films for semiconductor devices. According to one embodiment, a metal-carbon-oxygen high-k film is deposited by alternately and sequentially exposing a substrate to a metal-carbon precursor and near saturation exposure level of an oxidation source containing ozone. The method is capable of forming a metal-carbon-oxygen high-k film with good thickness uniformity while impeding growth of an interface layer between the metal-carbon-oxygen high-k film and the substrate. According to one embodiment, the metal-carbon-oxygen high-k film may be treated with an oxidation process to remove carbon from the film.Type: GrantFiled: December 21, 2007Date of Patent: June 21, 2011Assignee: Tokyo Electron LimitedInventors: Robert D. Clark, Cory Wajda

Publication number: 20110124204Abstract: A semiconductor device manufacturing method includes: forming a layer on a substrate by supplying source gas into a process vessel; changing the layer into an oxide layer by supplying gases containing oxygen and hydrogen into the process vessel heated and kept lower than atmospheric pressure; and forming an oxide film on the substrate by alternately repeating the forming of the layer and the changing of the layer while purging an inside of the process vessel therebetween. In the forming of the layer, the source gas is supplied toward the substrate through a nozzle at a side of the substrate, and inert or hydrogen-containing gas is supplied together with the source gas through the nozzle toward the substrate, such that the velocity of the source gas flowing parallel to the substrate is greater than the velocity of the inert gas flowing parallel to the substrate in the purging of the process vessel.Type: ApplicationFiled: November 19, 2010Publication date: May 26, 2011Applicant: Hitachi-Kokusai Electric Inc.Inventors: Yosuke Ota, Naonori Akae, Yushin Takasawa, Yoshiro Hirose
