Patent number: 11967556Abstract: Methods for forming microelectronic devices include forming a staircase structure in a stack structure having a vertically alternating sequence of insulative and conductive materials arranged in tiers. Steps are at lateral ends of the tiers. Contact openings of different aspect ratios are formed in fill material adjacent the staircase structure, with some openings terminating in the fill material and others exposing portions of the conductive material of upper tiers of the stack structure. Additional conductive material is selectively formed on the exposed portions of the conductive material. The contact openings initially terminating in the fill material are extended to expose portions of the conductive material of lower elevations. Contacts are formed, with some extending to the additional conductive material and others extending to conductive material of the tiers of the lower elevations. Microelectronic devices and systems incorporating such staircase structures and contacts are also disclosed.Type: GrantFiled: October 25, 2021Date of Patent: April 23, 2024Inventors: Biow Hiem Ong, David A. Daycock, Chieh Hsien Quek, Chii Wean Calvin Chen, Christian George Emor, Wing Yu Lo

Publication number: 20230142487Abstract: Embodiments are directed to the generation of a token associated with a status. The status of the token may affect how the token is treated and the types of restrictions placed on the token. The status of the token may indicate that the token is generated based on verification of secure user data. Alternatively, the status of the token may indicate that the token is generated based on insufficient user data and, as such, restrictions may be imposed on the token. The token requestor may be a mobile application, such as a merchant mobile application provisioned on a user device. In response to a token request from the merchant, the token provider issues tokens with varying status based on a confidence level. The status of the token may be indicated in terms of token assurance level.Type: ApplicationFiled: January 9, 2023Publication date: May 11, 2023Applicant: Visa International Service AssociationInventors: Vishwanath Shastry, Shalini Mayor, Calvin Chen

Publication number: 20200232098Abstract: Methods of patterning electroless metals on a substrate are presented. The substrate is covered by a blocking reagent. After formation of a catalyst blocking layer on the substrate, portions of the catalyst blocking layer are removed to form a circuit pattern. A catalyst is placed the surfaces of both the catalyst blocking layer and the exposed substrate. The catalyst blocking layer prevents or reduces catalytic activity of the catalyst. Electroless metal plating is performed to plate a metal at the active portions of the catalyst.Type: ApplicationFiled: January 21, 2020Publication date: July 23, 2020Inventors: Michael Riley VINSON, Sunity K.

Publication number: 20200190670Abstract: Devices, systems, and methods are contemplated for depositing metals to the surface of a substrate. A first precursor ink including a metal is applied to a surface of the substrate, and the precursor ink is reduced to deposit the metal to the substrate, preferably by thermal reduction, forming a first metal layer. A second precursor ink having a second metal is then applied to the substrate, at least partially over the first metal layer. The second precursor ink is then reduced, typically by chemical reduction, depositing the second metal over the first metal layer in a globular fashion. Precursor inks are also disclosed having an alkyl metal carboxylate, a cyclic amine, and at least one of an ester, a hydrocarbon, or an ether.Type: ApplicationFiled: December 13, 2019Publication date: June 18, 2020Inventors: Sunity K SHARMA, Calvin CHEN, Shinichi IKETANI, Michael Riley VINSON

Publication number: 20040044753Abstract: A system and method is provided for managing a network using business information based on data from the network elements, where the data includes real time data. One preferred embodiment of the present invention comprises a method for managing a network having a network element. First, a real time variable of the network element is selected for dynamic monitoring in a cell on a spreadsheet. Next, the real time variable is measured. And then the measured real time variable is used, for example, displayed, in the cell. In addition, the measured real time variable can be combined with other business data to form a flexible business analysis application.Type: ApplicationFiled: February 27, 2002Publication date: March 4, 2004Applicant: Lucida, Inc.Inventors: Yasufumi Toyoshima, Calvin Chen
