Patent number: 7807535Abstract: The invention includes methods of forming layers comprising epitaxial silicon. In one implementation, an opening is formed within a first material received over a monocrystalline material. Opposing walls, of a second material, are formed within the opening which are laterally displaced inwardly of the opposing sidewalls, a space being received between the opposing walls and the opposing sidewalls, with monocrystalline material being exposed between the opposing walls within the opening. A silicon-comprising layer is epitaxially grown from the exposed monocrystalline material within the second material-lined opening. Other aspects and implementations are contemplated.Type: GrantFiled: February 28, 2007Date of Patent: October 5, 2010Assignee: Micron Technology, Inc.Inventors: Nirmal Ramaswamy, Gurtej S.

Patent number: 7498057Abstract: A deposition method includes positioning a substrate within a deposition chamber defined at least in part by chamber walls. At least one of the chamber walls comprises a chamber surface having a plurality of purge gas inlets to the chamber therein. A process gas is provided over the substrate effective to deposit a layer onto the substrate. During such providing, a material adheres to the chamber surface. Reactive purge gas is emitted to the deposition chamber from the purge gas inlets effective to form a reactive gas curtain over the chamber surface and away from the substrate, with such reactive gas reacting with such adhering material. Further implementations are contemplated.Type: GrantFiled: March 8, 2005Date of Patent: March 3, 2009Assignee: Micron Technology, Inc.Inventors: Demetrius Sarigiannis, Garo J.

Publication number: 20080241386Abstract: The invention includes an atomic layer deposition method of forming a layer of a deposited composition on a substrate. The method includes positioning a semiconductor substrate within an atomic layer deposition chamber. On the substrate, an intermediate composition monolayer is formed, followed by a desired deposited composition from reaction with the intermediate composition, collectively from flowing multiple different composition deposition precursors to the substrate within the deposition chamber. A material adheres to a chamber internal component surface from such sequentially forming. After such sequentially forming, a reactive gas flows to the chamber which is different in composition from the multiple different deposition precursors and which is effective to react with such adhering material. After the reactive gas flowing, such sequentially forming is repeated. Further implementations are contemplated.Type: ApplicationFiled: May 5, 2008Publication date: October 2, 2008Applicant: MICRON TECHNOLOGY, INC.Inventors: Demetrius Sarigiannis, Garo J.
