In one embodiment, a method generally includes providing a substrate carrier having a first surface and a second surface, the first surface is configured to support a substrate and being parallel and opposite to the second surface, subjecting the second surface of the substrate carrier to a surface treatment process to roughen the second surface of the substrate carrier, wherein the substrate carrier contains a material comprising silicon carbide, and forming an oxide-containing layer on the roughened second surface of the substrate carrier. The formed oxide-containing layer has optical absorption properties at wavelengths close to the radiation delivered from one or more energy sources used to heat the chamber component.Type: ApplicationFiled: April 25, 2011Publication date: November 10, 2011Applicant: APPLIED MATERIALS, INC.Inventors: HIROJI HANAWA, Kyawwin Jason Maung

Patent number: 8034655Abstract: A method of forming a non-volatile resistive oxide memory cell includes forming a first conductive electrode of the memory cell as part of a substrate. Insulative material is deposited over the first electrode. An opening is formed into the insulative material over the first electrode. The opening includes sidewalls and a base. The opening sidewalls and base are lined with a multi-resistive state layer comprising multi-resistive state metal oxide-comprising material which less than fills the opening. A second conductive electrode of the memory cell is formed within the opening laterally inward of the multi-resistive state layer lining the sidewalls and elevationally over the multi-resistive state layer lining the base. Other aspects and implementations are contemplated.Type: GrantFiled: April 8, 2008Date of Patent: October 11, 2011Assignee: Micron Technology, Inc.Inventors: John Smythe, Bhaskar Srinivasan, Gurtej Sandhu

Publication number: 20110233719Abstract: The invention relates to a test method comprising an electrical connection contact on the support of a substrate of the semiconductor-on-insulator type. This method is remarkable in that it comprises the steps of: a) taking a substrate of the semiconductor-on-insulator type comprising a support substrate entirely covered with an insulator layer and an active layer, a portion of the insulator layer being buried between the active layer and the front face of the support substrate, b) removing a portion of the insulator layer that extends at the periphery of the front face of the support substrate and/or that extends on its rear face, so as to delimit at least one insulator-free accessible area of the support substrate, while retaining at least one portion of the insulator layer on the rear face, c) applying an electrical voltage to the accessible area in order to make the electrical connection contact.Type: ApplicationFiled: January 14, 2010Publication date: September 29, 2011Applicant: S.O.I.TEC SILICON ON INSULATOR TECHNOLOGIESInventor: Chrystelle Lagahe Blanchard

Publication number: 20110217827Abstract: Fabricating single-walled carbon nanotube transistor devices includes removing undesirable types of nanotubes. These undesirable types of nanotubes may include nonsemiconducting nanotubes, multiwalled nanotubes, and others. The undesirable nanotubes may be removed electrically using voltage or current, or a combination of these. This approach to removing undesirable nanotubes is sometimes referred to as “burn-off.” The undesirable nanotubes may be removed chemically or using radiation. The undesirable nanotubes of an integrated circuit may be removed in sections or one transistor (or a group of transistors) at a time in order to reduce the electrical current used or prevent damage to the integrated circuit during burn-off.Type: ApplicationFiled: May 17, 2011Publication date: September 8, 2011Applicant: ETAMOTA CORPORATIONInventor: Thomas W. Tombler, JR.

Publication number: 20110215289Abstract: A reconfigurable device and a method of creating, erasing, or reconfiguring the device are provided. At an interface between a first insulating layer and a second insulating layer, an electrically conductive, quasi one- or zero-dimensional electron gas is present such that the interface presents an electrically conductive region that is non-volatile. The second insulating layer is of a thickness to allow metal-insulator transitions upon the application of a first external electric field. The electrically conductive region is subject to erasing upon application of a second external electric field.Type: ApplicationFiled: May 13, 2011Publication date: September 8, 2011Inventor: Jeremy Levy
