Publication number: 20230260845Abstract: Disclosed are wafer structures and semiconductor devices. A semiconductor device may include a substrate and a cell array structure on the substrate. The substrate may include a device region and a dummy region surrounding the device region in a plan view. The cell array structure may include a plurality of first dielectric layers, a plurality of gate structures, a vertical channel structure, and a dummy pattern. The vertical channel structure may be on the device region and may penetrate the plurality of gate structures and the plurality of first dielectric layers. The cell array structure includes an outer sidewall above an edge of the substrate and a recessed portion on the outer sidewall of the cell array structure. The dummy pattern may cover a sidewall of the recessed portion and a bottom surface of the recessed portion. The dummy pattern and vertical channel structure may include a same material.Type: ApplicationFiled: August 26, 2022Publication date: August 17, 2023Applicant: Samsung Electronics Co., Ltd.Inventors: Junyun KWEON, YeongBeom KO, Wooju KIM, Heejae NAM, Jungseok RYU, Junho YOON

Publication number: 20220415842Abstract: A semiconductor package includes a semiconductor chip on a substrate. The semiconductor chip includes an active region, and a scribe lane in continuity with an edge of the active region. A non-conductive film (NCF) is between the substrate and the semiconductor chip, the non-conductive film (NCF) at least partially defines a recess region overlapping with the scribe lane in plan view and extending on the active region.Type: ApplicationFiled: November 30, 2021Publication date: December 29, 2022Applicant: Samsung Electronics Co., Ltd.Inventors: Yeongbeom KO, Wooju KIM, Heejae NAM, Jungseok RYU, Haemin PARK

Patent number: 8386485Abstract: A service-oriented system architecture includes a computer-implemented search method and computer-implemented agent system for enabling efficient information searches on, for example, on XML databases, relational databases, and files located on intranets, the Internet, or other computer network systems. Referred to as the Knowledge Sifter architecture, the architecture may comprise, in one embodiment, a community of cooperating agents. The system architecture may be employed using a variety of methodologies, such as a case-based framework, collaborative filtering, or hybrid filtering. The case-based framework may be configured to recommend query specifications and refinements based on previously-stored user-query cases. Collaborative filtering involves the architecture recommending a set of unseen items that are preferred by other users to the active user. Hybrid filtering combines collaborative filtering and content-based filtering.Type: GrantFiled: July 31, 2009Date of Patent: February 26, 2013Assignee: George Mason Intellectual Properties, Inc.Inventors: Larry Kerschberg, Wooju Kim, Hanjo Jeong, Yong Uk Song

Publication number: 20110029514Abstract: Disclosed is a computer-implemented search method and computer-implemented agent system for efficient searching of information. Information may be located, for example, on XML databases, relational databases and files located on intranets and the Internet or other like computer network systems. Specifically, a service-oriented system architecture (also referred to as the Knowledge Sifter architecture), may be comprised of a community of cooperating agents. The system architecture may further be employed using a case-based framework configured to recommend query specifications and refinements based on previously-stored user-query cases. Other methodologies such as collaborative filtering, wherein the architecture can recommend a set of unseen items that are preferred by other users to the active user, can be used. Additionally, a hybrid filtering approach which combines both collaborative filtering and content-based filtering can be used effectively in the Knowledge Sifter architecture.Type: ApplicationFiled: July 31, 2009Publication date: February 3, 2011Inventors: Larry Kerschberg, Wooju Kim, Hanjo Jeong, Yong Uk Song
