Patent number: 8053029Abstract: Disclosed is a method for fabricating a CuInS2 thin film by metal-organic chemical vapor deposition (MOCVD). The method comprises fabricating a copper thin film by depositing an asymmetric copper precursor on a substrate by MOCVD and fabricating a CuInS2 thin film by depositing an indium-sulfur-containing precursor on the copper thin film by MOCVD. The method enables fabrication of a CuInS2 thin film with a constant composition even under vacuum as well as an argon (Ar) atmosphere. Disclosed is further a CuInS2 thin film fabricated by the method. Disclosed is further a method for fabricating an In2S3 thin film for a window of a solar cell via deposition of an indium-sulfur-containing precursor on the CuInS2 thin film by MOCVD. Disclosed further is an In2S3 thin film fabricated by the method. The In2S3 thin film is useful for a substitute for CdS conventionally used for windows of solar cells and contributes to simplification in fabrication process of solar cells.Type: GrantFiled: July 10, 2007Date of Patent: November 8, 2011Assignees: Samsung SDI Co., Ltd., Samsung Electronics Co., Ltd., Seoul National University Industry Foundation, Chung-Ang University Industry-Academy Cooperation FoundationInventors: Il Wun Shim, Seung Soo Lee, Kook Won Seo, Jong Pil Park

Publication number: 20110223320Abstract: A method of forming a material over a substrate includes performing at least one iteration of the following temporally separated ALD-type sequence. First, an outermost surface of a substrate is contacted with a first precursor to chemisorb a first species onto the outermost surface from the first precursor. Second, the outermost surface is contacted with a second precursor to chemisorb a second species different from the first species onto the outermost surface from the second precursor. The first and second precursors include ligands and different central atoms. At least one of the first and second precursors includes at least two different composition ligands. The two different composition ligands are polyatomic or a lone halogen. Third, the chemisorbed first species and the chemisorbed second species are contacted with a reactant which reacts with the first species and with the second species to form a reaction product new outermost surface of the substrate.Type: ApplicationFiled: March 9, 2010Publication date: September 15, 2011Inventors: Zhe Song, Chris M.

Patent number: 8017182Abstract: Films are deposited on a substrate by a process in which atomic layer deposition (ALD) is used to deposit one layer of the film and pulsed chemical vapor deposition (CVD) is used to deposit another layer of the film. During the ALD part of the process, a layer is formed by flowing sequential and alternating pulses of mutually reactive reactants that deposit self-limitingly on a substrate. During the pulsed CVD part of the process, another layer is deposited by flowing two CVD reactants into a reaction chamber, with at least a first of the CVD reactants flowed into the reaction chamber in pulses, with those pulses overlapping at least partially with the flow of a second of the CVD reactants. The ALD and CVD parts of the process ca be used to deposit layers with different compositions, thereby forming, e.g., nanolaminate films. Preferably, high quality layers are formed by flowing the second CVD reactant into the reaction chamber for a longer total duration than the first CVD reactant.Type: GrantFiled: June 21, 2007Date of Patent: September 13, 2011Assignee: ASM International N.V.Inventors: Menso Hendriks, Martin Knapp, Suvi Haukka

Patent number: 7981473Abstract: A process in which a wafer is exposed to a first chemically reactive precursor dose insufficient to result in a maximum saturated ALD deposition rate on the wafer, and then to a second chemically reactive precursor dose, the precursors being distributed in a manner so as to provide substantially uniform film deposition. The second chemically reactive precursor dose may likewise be insufficient to result in a maximum saturated ALD deposition rate on the wafer or, alternatively, sufficient to result in a starved saturating deposition on the wafer. The process may or may not include purges between the precursor exposures, or between one set of exposures and not another.Type: GrantFiled: March 1, 2004Date of Patent: July 19, 2011Assignee: Aixtron, Inc.Inventors: Gi Youl Kim, Anuranjan Srivastava, Thomas E.

Patent number: 7968452Abstract: This disclosure provides (a) methods of making an oxide layer (e.g., a dielectric layer) based on titanium oxide, to suppress the formation of anatase-phase titanium oxide and (b) related devices and structures. A metal-insulator-metal (“MIM”) stack is formed using an ozone pretreatment process of a bottom electrode (or other substrate) followed by an ALD process to form a TiO2 dielectric, rooted in the use of an amide-containing precursor. Following the ALD process, an oxidizing anneal process is applied in a manner is hot enough to heal defects in the TiO2 dielectric and reduce interface states between TiO2 and electrode; the anneal temperature is selected so as to not be so hot as to disrupt BEL surface roughness. Further process variants may include doping the titanium oxide, pedestal heating during the ALD process to 275-300 degrees Celsius, use of platinum or ruthenium for the BEL, and plural reagent pulses of ozone for each ALD process cycle.Type: GrantFiled: June 30, 2009Date of Patent: June 28, 2011Assignee: Intermolecular, Inc.Inventors: Hanhong Chen, Pragati Kumar, Sunil Shanker, Edward Haywood, Sandra Malhotra, Imran Hashim, Nobi Fuchigami, Prashant Phatak, Monica Mathur
