Abstract Inclusion of cerium (Ce) oxide particles as an abrasive into chemical mechanical planarization (CMP) slurries has become popular for wafer fabs below the 45nm technology node due to better polishing quality and improved CMP selectivity. Transmission electron microscopy (TEM) has difficulties finding and identifying Ce-oxide residuals due to the limited region of analysis unless dedicated efforts to search for them are employed. This article presents a case study that proved the concept in which physical evidence of Ce-rich particles was directly identified by analytical TEM during a CMP tool qualification in the early stage of 20nm node technology development. This justifies the need to setup in-fab monitoring for trace amounts of CMP residuals in Si-based wafer foundries. The fact that Cr resided right above the Ce-O particle cluster, further proved that the Ce-O particles were from the wafer and not introduced during the sample preparation.

Abstract For SRAMs with high logic complexity, hard defects, design debug, and soft defects have to be tackled all at once early on in the technology development while innovative integration schemes in front-end of the line are being validated. This paper presents a case study of a high-complexity static random access memory (SRAM) used during a 32nm technology development phase. The case study addresses several novel and unrelated fail mechanisms on a product-like SRAM. Corrective actions were put in place for several process levels in the back-end of the line, the middle of the line, and the front-end of the line. These process changes were successfully verified by demonstrating a significant reduction of the Vmax and Vmin nest array block fallout, thus allowing the broader development team to continue improving random defectivity.

Ever since the outbreak of the COVID-19 pandemic, questions of whom or what to trust have become paramount. This article examines the public debates surrounding the initial development of the German Corona-Warn-App in 2020 as a case study to analyse such questions at the intersection of trust and trustworthiness in technology development, design and oversight. Providing some insights into the nature and dynamics of trust and trustworthiness, we argue that (a) trust is only desirable and justified if placed well, that is, if directed at those being trustworthy; that (b) trust and trustworthiness come in degrees and have both epistemic and moral components; and that (c) such a normatively demanding understanding of trust excludes technologies as proper objects of trust and requires that trust is directed at socio-technical assemblages consisting of both humans and artefacts. We conclude with some lessons learned from our case study, highlighting the epistemic and moral demands for trustworthy technology development as well as for public debates about such technologies, which ultimately requires attributing epistemic and moral duties to all actors involved.

Purpose The purpose of this paper is to explore, identify and gain insight into factors related to electronic records and information management (e-RIM) issues and their influence on the implementation of e-RIM initiative in military service in Malaysia. This exploration was conducted via a literature review and case study. Design/methodology/approach This study adopted a qualitative approach and used a case study involving two army departments in Malaysia. Interviews triangulated by document content analysis and observations were used for data collection. The data were analysed using a directional content analysis approach. Findings This study reveals that people, organizations, technology and processes are the interrelated contexts underlying e-RIM issues which inevitably influence the implementation of e-RIM initiatives. Competency and leadership, governance structure, culture and strategic planning, technology development and record-keeping process are the main factors impacting such efforts, in turn forming potential obstacles for organizations implementing such initiatives. Research limitations/implications The research approach and design adopted and the sample size were insufficient for generalization of the findings. Practical implications This study shows that e-RIM initiatives pose greater challenges related to various issues that cause difficulties in improving and implementing the initiative. Thus, it is crucial for organizations to ascertain and comprehend the factors that influence e-RIM initiatives prior to formulating strategies and approaches in addressing those factors, which would in turn affect the implementation of e-RIM initiatives. Originality/value This study provides insights into the fundamental factors embracing the e-RIM issues which influence the initiatives, and thereby fosters further discussion and research in the subject matter in Malaysia.
