Patent number: 11984362Abstract: A method of fabricating an integrated circuit includes forming a first opening having a first width and a second opening having a second width in a first dielectric layer over a silicon substrate. The openings expose the silicon substrate and the exposed silicon substrate is oxidized to form first and second LOCOS structures having a first thickness. A polysilicon layer is formed over the silicon substrate, so that the polysilicon layer fills the first and second openings. A blanket etch of the polysilicon layer is performed to remove at least a portion of the polysilicon layer over the second LOCOS structure while leaving the first LOCOS structure protected by the polysilicon layer. The silicon substrate under the second LOCOS structure is further oxidized such that the second LOCOS structure has a second thickness greater than the first thickness.Type: GrantFiled: August 25, 2021Date of Patent: May 14, 2024Assignee: Texas Instruments IncorporatedInventors: Abbas Ali, Christopher Scott Whitesell, John Christopher Shriner, Henry Litzmann Edwards

Publication number: 20240082518Abstract: Apparatus for generating a supply of air at positive pressure for the amelioration or treatment of a respiratory disorder includes a first chamber, a second chamber, at least one inlet tube structured and configured to allow ambient air to enter the first chamber, at least one flow tube structured and configured to allow air to pass from the first chamber to the second chamber, and a blower structured and configured to produce a flow of air at positive pressure. The blower is positioned in the first chamber and structured and configured to receive air from the second chamber. The blower includes a housing structured and configured to sealingly separate air flow through an interior of the housing from the first chamber. The at least one inlet tube is axially spaced from the at least one flow tube.Type: ApplicationFiled: November 13, 2023Publication date: March 14, 2024Inventors: Melanie Lucia CARIOLA, Christopher Scott EDWARDS, Jeegarkumar KAPADIA, Barton John KENYON, Michael Bruce MOIR, Timothy Nicholas SHADIE, Robert John SPARROW, Zhuo Ran TANG
