Patent number: 11417525Abstract: Methods of self-aligned multiple patterning. A hardmask is deposited over an interlayer dielectric layer. A mandrel is formed over the hardmask. A block mask is formed that covers a first lengthwise section of the mandrel and that exposes second and third lengthwise sections of the mandrel. After forming the block mask, the second and third lengthwise sections of the mandrel are removed to define a pattern including respective first and second mandrel lines that are separated from each other by the first lengthwise section of the mandrel. The first mandrel line and the second mandrel line expose respective portions of the hardmask, and the first lengthwise section of the mandrel line covers another portion of the hardmask. The pattern is transferred to the hardmask with an etching process, and subsequently transferred to the interlayer dielectric layer with another etching process.Type: GrantFiled: October 8, 2018Date of Patent: August 16, 2022Assignee: GlobalFoundries U.S. Inc.Inventors: Martin O'Toole, Keith Donegan, Brendan O'Brien, Hsueh-Chung Chen, Terry A.

Patent number: 11270912Abstract: Example embodiments relate to methods for forming via holes self-aligned with metal blocks on substrates. One embodiment includes a method where the substrate includes an interlayer dielectric layer. The method includes forming a metallic layer on the interlayer dielectric layer. The method also includes forming a dielectric layer on the metallic layer and forming a plurality of parallel spacer line structures on the dielectric layer. In addition, the method includes forming a sidewall oxide, a first sacrificial layer, and an opening in the first sacrificial layer. Further, the method includes etching the dielectric layer and removing the first sacrificial layer. Additionally, the method includes forming a second sacrificial layer, forming an opening in the second sacrificial layer, depositing a metal block on the metallic layer, and removing the second sacrificial layer. Still further, the method includes etching the metallic layer and the interlayer dielectric layer to form a via hole.Type: GrantFiled: December 3, 2020Date of Patent: March 8, 2022Assignee: IMEC VZWInventors: Martin O'Toole, Christopher Wilson, Zsolt Tokei, Ryan Ryoung han Kim

Patent number: 11264271Abstract: A method is provided for producing electrically conductive lines (23a, 23b), wherein spacers are deposited on a sacrificial structure present on a stack of layers, including a hardmask layer on top of a dielectric layer into which the lines are to be embedded, and an intermediate layer on top of the hardmask layer. A self-aligned litho-etch step is then performed to create an opening in the intermediate layer, the opening being self-aligned to the space between two adjacent sidewalls of the sacrificial structure. This self-aligned step precedes the deposition of spacers on the sacrificial structure, so that spacers are also formed on the transverse sidewalls of the opening, i.e. perpendicular to the spacers on the walls of the sacrificial structure. A blocking material is provided in the area of the bottom of the opening that is surrounded on all sides by spacers, thereby creating a block with a reduced size.Type: GrantFiled: October 27, 2020Date of Patent: March 1, 2022Assignee: IMEC VZWInventors: Martin O'Toole, Zsolt Tokei, Christopher Wilson, Stefan Decoster

Patent number: 10784119Abstract: Methods of self-aligned multiple patterning. First and second mandrels are formed over a hardmask, and a conformal spacer layer is deposited over the first mandrel, the second mandrel, and the hardmask between the first mandrel and the second mandrel. A planarizing layer is patterned to form first and second trenches that expose first and second lengthwise portions of the conformal spacer layer respectively between the first and second mandrels. After patterning the planarizing layer, the first and second lengthwise portions of the conformal spacer layer are removed with an etching process to expose respective portions of the hardmask along a non-mandrel line. A third lengthwise portion of the conformal spacer layer is masked during the etching process by a portion of the planarizing layer and defines a non-mandrel etch mask.Type: GrantFiled: October 8, 2018Date of Patent: September 22, 2020Assignee: GLOBALFOUNDRIES INC.Inventors: Ravi Prakash Srivastava, Hsueh-Chung Chen, Steven McDermott, Martin O'Toole, Brendan O'Brien, Terry A.

Publication number: 20190361015Abstract: Immunosensors according to present embodiments combine a sandwich bioassay with an electro-active, integrated optical waveguide (EA-IOW) for the detection of infectious pathogens and other analytes from a sample, whereby the electro-active waveguide surface is functionalized with a capture antibody capable of specific binding with a particular antigen. This functionalized arrangement then promotes the binding of a secondary, labeled antibody serving as a redox probe, which produces an analytical signal having unique spectral and electrochemical properties for the detection of virus antigens, pathogens, and other analytes that bind to proteins.Type: ApplicationFiled: January 23, 2018Publication date: November 28, 2019Applicant: UNIVERSITY OF LOUISVILLE RESEARCH FOUNDATION, INC.Inventors: Sergio Brito Mendes, Martin O'Toole

Patent number: 9830565Abstract: One or more techniques and/or systems are provided for service notification. A notification component may be associated with a hygiene device, such as a material dispenser. The notification component may receive a service notification request (e.g., an infrared signal or other wireless signal) from a maintenance management device (e.g., a computing device associated with a maintenance cart or mobile device of a housekeeper) based upon the maintenance management device being within a communication threshold distance of the hygiene device. The notification component may evaluate a current operational status of the hygiene device to determine a service notification to provide (e.g., a low battery alert, a refill container level indicator, etc.). The service notification may be provided through the hygiene device or through the maintenance management device to the housekeeper (e.g., a blinking light, an audible notification, a textual notification, etc.).Type: GrantFiled: December 16, 2015Date of Patent: November 28, 2017Assignee: GOJO INDUSTRIES, INC.Inventor: Martin O'Toole

Patent number: 9468986Abstract: Methods of effecting bond adhesion between metal structures, methods of preparing articles including bonded metal structures, and articles including bonded metal structures are provided herein. In an embodiment, a method of effecting bond adhesion between metal structures includes forming a first metal structure on a substrate. The first metal structure includes grains that have a {111} crystallographic orientation, and the first metal structure has an exposed contact surface. Formation of an uneven surface topology is induced in the exposed contact surface of the first metal structure after forming the first metal structure. A second metal structure is bonded to the exposed contact surface of the first metal structure after inducing formation of the uneven surface topology in the exposed contact surface.Type: GrantFiled: July 30, 2013Date of Patent: October 18, 2016Assignee: GLOBALFOUNDRIES, INC.Inventors: Ernesto Gene de la Garza, Martin O'Toole

Patent number: 9136234Abstract: When forming sophisticated semiconductor devices including metal pillars arranged on contact pads, which may comprise aluminum, device performance and reliability may be improved by avoiding exposure of the contact pad material to the ambient atmosphere, in particular during and between dicing and packaging processes. To this end, the contact pad material may be covered by a protection layer or may be protected by the metal pillars itself, thereby concurrently improving mechanical stress distribution in the device.Type: GrantFiled: July 9, 2013Date of Patent: September 15, 2015Assignee: GLOBALFOUNDRIES Inc.Inventors: Matthias Lehr, Marcel Wieland, Martin O'Toole
