Publication number: 20240105499Abstract: Embodiments of the present technology relate to semiconductor processing methods that include providing a structured semiconductor substrate including a trench having a bottom surface and top surfaces. The methods further include depositing a portion of a silicon-containing material on the bottom surface of the trench for at least one deposition cycle, where each deposition cycle includes: depositing the portion of the silicon-containing material on the bottom surface and top surfaces of the trench, depositing a carbon-containing mask layer on the silicon-containing material on the bottom surface of the trench, where the carbon-containing mask layer is not formed on the top surfaces of the trench, removing the portion of the silicon-containing material from the top surfaces of the trench, and removing the carbon-containing mask layer from the silicon-containing material on the bottom surface of the trench, where the as-deposited silicon-containing material remains on the bottom surface of the trench.Type: ApplicationFiled: September 28, 2022Publication date: March 28, 2024Applicant: Applied Materials, Inc.Inventors: Zeqing Shen, Susmit Singha Roy, Abhijit Basu Mallick, Xinke Wang, Xiang Ji, Praket Prakash Jha

Publication number: 20230009392Abstract: Methods for detecting digital or physical tampering of an imaged physical credential include the actions of: receiving a digital image representing a physical credential having one or more high value regions, the digital image including an array of pixels; processing the digital image with a tamper detector to generate an output corresponding to an intrinsic characteristic of the digital image, the tamper detector configured to perform a pixel-level analysis of the high value regions of the digital image with respect to a predetermined tampering signature; and determining, based on the output from the tamper detector, whether the digital image has been digitally tampered with.Type: ApplicationFiled: September 15, 2022Publication date: January 12, 2023Inventors: Richard Austin Huber, JR., Satya Prakash Mallick, Matthew William Flagg, Koustubh Sinhal

Publication number: 20220092333Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for an active lighting system. In one aspect, a method includes receiving a first image of the physical document having a first glare signature and a second image of the physical document having a second glare signature that is different from the first glare signature; determining a first glare map of the first image and a second glare map of the second image; comparing the first glare map to the second glare map; and generating the digital image based on the comparison of the first and second glare maps.Type: ApplicationFiled: December 6, 2021Publication date: March 24, 2022Inventors: Richard Austin Huber, JR., Matthew Willliam Flagg, Satya Prakash Mallick

Patent number: 11055354Abstract: Methods, systems, and devices for processing and answering a natural language query at a database server are described. An end user may submit a question in natural language over a communication platform. An answer engine running on the database server may receive the question, and may process the content of the question using natural language processing (NLP) techniques. The answer engine may construct a search query based on the NLP, and may retrieve a set of documents from a database using the search query. The answer engine may rank the documents, prune the number of documents, modify the documents for the given communication platform, or perform any combination of these functions. In some cases, an intermediate user may review the documents, and may select one or more documents for publication. The answer engine may send the selected documents to the end user as answers in response to the question.Type: GrantFiled: November 3, 2017Date of Patent: July 6, 2021Assignee: salesforce.com, inc.Inventors: Peter Francis White, Michael Micucci, Scott Douglas White, Weiping Peng, Anjan Goswami, Pranav Suresh Shah, Prakash Mallick, Pingping Xiu, Zhenhua Xu
