Abstract Multi-Chip Package (MCP) decapsulation is now becoming a rising problem. Because for traditional decapsulation method, acid can’t dissolve the top silicon die to expose the bottom die surface in MCP. It makes inspecting the bottom die in MCP is difficult. In this paper, a new MCP decapsulation technology combining mechanical polishing with chemical etching is introduced. This new technology can remove the top die quickly without damaging the bottom die using KOH and Tetra-Methyl Ammonium Hydroxide (TMAH). The technology process and relative application are presented. The factors that affect the KOH and TMAH etch rate are studied. The usage difference between the two etchant is discussed.

The project “Development of an Industry Test Facility and Qualification Processes for in-line inspection (ILI) technology Evaluation and Enhancements” aims to expand knowledge of ILI technology performance and identify gaps where new technology is needed. Additionally, this project also aims to provide ILI technology developers, researchers and pipeline operators a continuing resource for accessing test samples with a range of pipeline integrity threats and vintages; and inline technology test facilities at the Technology Development Center (TDC) of Pipeline Research Council International, Inc. (PRCI), a PRCI managed facility available for future industry and PHMSA research projects. An ILI pull test facility was designed and constructed as part of this project based on industry state-of-the-art and opportunities for capability improvement. The major ILI technology providers, together with pipeline operator team members, reviewed the TDC sample inventory and developed a series of ILI performance tests illustrating one of multiple possible research objectives, culminating in 16-inch and 24-inch nominal diameter test strings. The ILI technology providers proposed appropriate inspection tools based on the types of the integrity threats in the test strings, a series of pull tests of the provided ILI tools were performed, and the technology providers delivered reports of integrity anomaly location and dimensions for performance evaluation. Quantitative measures of detection and sizing performance were confidentially disclosed to the individual ILI technology providers. For instances where ILI predictions were outside of claimed performance, the vendors were given a limited sample of actual defect data to enable re-analysis, thus demonstrating the potential for improved integrity assessment with validation measurements. In this paper, an evaluation of the ILI data obtained from repeated pull-through testing on the 16 and 24-inch pipeline strings at the TDC is performed. The resulting data was aligned, analyzed, and compared to truth data and the findings of the evaluation are presented.

Learning Capacity

The Problem Initial explorations of virtual human resource development (VHRD) were published in the 12(6) issue of Advances, but these articles were only an initial step toward conceptualization. New perspectives on VHRD have developed over the past 4 years, particularly about human resource development’s (HRD) role in the development of new technology. The Solution This article provides a brief overview of existing published literature on VHRD, offers new conceptualizations of HRD’s role with technology development, and introduces the articles in this issue that advance their own new perspectives. This article argues that HRD must adopt new skills and develop explanatory models for growing organizational learning capacity in virtual work. The Stakeholders This article is of interest to practitioners and managers who lead technology projects and work within technology-enabled professional environments, as well as scholars interested in studying VHRD.

Purpose The next phase of hardware technology development is focused on alternative ways to manage and store consumers’ personal content. However, even consumers who have adopted Cloud-based services have demonstrated a reluctance to move all of their personal content into the Cloud and continue to resist giving up local hard drives. This paper aims to investigate the characteristics of local hard drives and the Cloud that lead to simultaneous use. Design/methodology/approach This paper uses content analysis of online comments and ten depth interviews with simultaneous users of local hard drives and the Cloud. Findings Three factors influence the resistance to giving up local hard drives. Simultaneous users utilize local hard drives as a redundancy system and as a way to ensure the permanence of their digital content. They are unsure of the Cloud’s ability to support their content creation, management and storage activities (task-technology fit). Research limitations/implications Study findings are based on qualitative methods and thus the results cannot be considered conclusive. Practical implications The authors speculate that it is unlikely that Cloud-only will fully replace hard drives until these factors are understood and addressed by information technology developers. Cloud service providers may not be aware of how little that users understand the Cloud. In contrast to their certainty and confidence in local hard drives, simultaneous users are confused as to what the Cloud is and how it functions. This uncertainty exacerbates their risk perception and need for control. Originality/value This is the first study exploring simultaneous use of local hard drives and the Cloud with a view to understanding this behaviour in terms of the relative advantage of the incumbent technology over the new technology.

Abstract Static Random Access Memory (SRAM) has long been used for a new technology development vehicle because it is sensitive to process defects due to its high density and minimum feature size. In addition, failure location can be accurately predicted because of the highly structured architecture. Thus, fast and accurate Failure Analysis (FA) of the SRAM failure is crucial for the success of new technology learning and development. It is often quite time consuming to identify defects through conventional physical failure analysis techniques. In this paper, we present an advanced defect identification methodology for SRAM bitcell failures with fast speed and high accuracy based on the bitcell transistor analog characteristics from special design for test (DFT) features, Direct Bitcell Access (DBA). This technique has the advantage to shorten FA throughput time due to a time efficient test method and an intuitive failure analysis method based on Electrical Failure Analysis (EFA) without destructive analysis. In addition, all the defects in a wafer can be analyzed and improved simultaneously utilizing the proposed defect identification methodology. Some successful case studies are also discussed to demonstrate the efficiency of the proposed defect identification methodology.

Constructive Technology Assessment

Engineering, understood as the gathering of scientific and technological knowledge for innovation, creation, advancement and optimization of techniques, as well as a set of useful tools to meet social needs and solve technical problems of both individuals and the community, makes its main actors, engineers, key players in sustainable development and in the creation of alternatives that minimize the negative effects of technology on society. It is in this sense that technology assessment approaches should take importance among those who manage technology development and implementation policies. Generally, the undesirable effects of the intrusion of a new technology are acted upon when they already occur, and technology assessment is intended to anticipate the risk. This paper presents a bibliographic review of technology assessment, its approaches and future study needs. Based on an articulating axis that positions technological change and innovation as an imperative need for social development, an exhaustive review of related articles in specialized databases was carried out. The most important results of this work reveal that the field of technological assessment has been strongly inclined towards the health or sanitary sector; however, research is being developed in central engineering topics such as the development of nanotechnology, robotics, and the handling of big data, where the European model stands out as a reference for technological assessment processes due to its inclusive and democratic nature.

HBCUs can utilize new technology with the purpose of appealing to the growing market of nontraditional students. This chapter also expounds on the concept that simply introducing technology does not necessarily translate into higher student achievement. Improper implementation of technology can result in a lowering of academic productivity. HBCUs must invest heavily in development for its faculty and staff in best practices in online instruction such that their students can have the most rewarding academic experience possible. University administration must engage in their own leadership and technology development such that they can instill the necessary level of buy-in from all levels of University personnel to ensure the highest possibility of success in attracting, educating, and graduating the growing numbers nontraditional students. This chapter's significance to student engagement and retention is that HBCU's must explore ways of attracting students of the technology age, while providing them with challenging curricula that are conducive to the nontraditional student's life style.
