Patent number: 7335569Abstract: The invention describes an in-situ method of fabricating a metal insulator metal (MIM) capacitor and products formed by the same. The method utilizes atomic layer deposition (ALD) or metal-organic chemical vapor deposition (MOCVD). In the method, a metal precursor is sequentially reacted with a nitrogen source, oxidant, and then a nitrogen source again. Reaction with the nitrogen source generates the outermost conductive metal nitride (MN) layers (121). Reaction with the oxidant generates an inner dielectric metal oxide (MOx) layer (110). Alternatively, or in addition, the metal precursor can be reacted with a mixture of oxidant and nitrogen source to generate inner dielectric layer(s) (231, 232, 310) of metal oxynitride (MOxNy). Because the same metal is used throughout the capacitor, the layers in the MIM capacitor exhibits excellent compatibility and stability.Type: GrantFiled: July 18, 2003Date of Patent: February 26, 2008Assignee: Aviza Technology, Inc.Inventor: Yoshihide Senzaki

In one embodiment, dielectric layers in a build-up interconnect have a gradation in glass transition temperature; and the later applied dielectric layers are laminated at temperatures lower than the glass transition temperatures of the earlier applied dielectric layers. In one embodiment, the glass transition temperatures of earlier applied dielectric films in a build-up interconnect are increased through a thermosetting process to exceed the temperature for laminating the later applied dielectric films. In one embodiment, a polyimide material is formed with embedded catalysts to promote cross-linking after a film of the polyimide material is laminated (e.g., through photo-chemical or thermal degradation of the encapsulant of the catalysts).Type: GrantFiled: September 22, 2004Date of Patent: February 26, 2008Assignee: Intel CorporationInventor: Ravindra V.

Patent number: 7335609Abstract: A chemical vapor deposition method for forming a dielectric material in a trench formed on a substrate. The method includes flowing a silicon-containing precursor into a process chamber housing the substrate, flowing an oxidizing gas into the chamber, and providing a hydroxyl-containing precursor in the process chamber. The method also includes reacting the silicon-containing precursor, oxidizing gas and hydroxyl-containing precursor to form the dielectric material in the trench. The ratio of the silicon-containing precursor to the oxidizing gas flowed into the chamber is increased over time to alter a rate of deposition of the dielectric material.Type: GrantFiled: August 26, 2005Date of Patent: February 26, 2008Assignee: Applied Materials, Inc.Inventors: Nitin K. Ingle, Shan Wong, Xinyun Xia, Vikash Banthia, Won B. Bang, Yen-Kun V. Wang

Patent number: 7335611Abstract: A method of forming a conductor in a thin film structure on a semiconductor substrate includes forming high aspect ratio openings in a base layer having vertical side walls, depositing a dielectric barrier layer comprising a dielectric compound of a barrier metal on the surfaces of the high aspect ratio openings including the vertical side walls, depositing a metal barrier layer comprising the barrier metal on the first barrier layer, depositing a main conductor species seed layer on the metal barrier layer and depositing a main conductor layer. The method further includes annealing the main conductor layer by (a) directing light from an array of continuous wave lasers into a line of light extending at least partially across the thin film structure, and (b) translating the line of light relative to the thin film structure in a direction transverse to the line of light.Type: GrantFiled: August 8, 2005Date of Patent: February 26, 2008Assignee: Applied Materials, Inc.Inventors: Kartik Ramaswamy, Hiroji Hanawa, Biagio Gallo, Kenneth S.

Patent number: 7335612Abstract: Disclosed are a mesh cotton with a separating net on a surface thereof and a method of manufacturing the same. The mesh cotton (10) is manufactured by layering a plurality of cotton sheets (13) and adhering the layered cotton sheets to each other with an acryl binder, embossing a surface of the layered cotton sheets, and forming a transparent mesh-type separating net (11) using a dilution of a mixture of ethylene copolymers on an outer surface of the layered cotton sheets. The separating net is also formed by applying in a mesh form a dilution of a mixture of a wax or a paraffin and the mixture of ethylene copolymers to an outer surface of the layered mesh cotton, and solidifying the dilution. The separating net may further include an antioxidant and other additives. The mesh cotton is completely removed from applied wound sites by the separating net, and maintains elasticity while the layered cotton sheets are not easily separated from each other.Type: GrantFiled: July 23, 2004Date of Patent: February 26, 2008Inventor: Tack-Young Kim
