Intracranial interhemispheric osteochondrolipoma: Diagnostic and surgical challenges in an extremely rare entity
Authors: Rajeshwari Madhu , Suri Vaishali , Kaur Kavneet , Suri Ashish , Garg Ajay , Sharma Mehar Chand , Sarkar Chitra
Published: May 2016

Intracranial lipomas are rare developmental lesions, predominantly occurring in the interhemispheric location. Osteochondrolipoma is an extremely rare variant of lipoma with osseous and chondroid differentiation. We present a case of interhemispheric osteochondrolipoma, in a 2.5‐years‐old male child which was detected antenatally, in association with corpus callosum agenesis. The lesion progressively increased in size with resulting compression of surrounding structures, and was subjected to microsurgical decompression. To the best of our knowledge, this is the first case of intracranial interhemispheric osteochondrolipoma in the existing medical literature. Peculiarities of this case and the diagnostic and surgical challenges are discussed.
The Impact of Inappropriate Implantable Cardiac Defibrillator Shocks on Cardiovascular Morbidity and Mortality
Authors: MEHTA NISHAKI K. , TAYLOR MONTOYA , KALBFLEISCH STEVEN
Published: May 2016

Background

The impact of inappropriate implantable cardiac defibrillator (ICD) shocks on cardiac outcomes is controversial. Shocks due to lead noise are unique in that they are not an outcome of worsening rhythm status. In this study, we compared the outcome of patients with and without inappropriate shocks who underwent Sprint Fidelis lead (Medtronic Inc., Minneapolis, MN, USA) extraction.

Methods

We retrospectively identified 147 patients who underwent Sprint Fidelis lead extraction in our institution between May 2007 and August 2012. The patients were separated into those with (Group 1) and without (Group 2) inappropriate shocks due to lead noise. Pertinent data were obtained from chart review.

Results

There were 57 and 90 patients in Groups 1 and 2, respectively. The mean ± standard deviation number of inappropriate shocks in Group 1 was 16 ± 22. There was no difference in the baseline demographics, risk factors, and cardiac history between the groups. There were no extraction‐related deaths and there was no difference in the rate of periprocedural complications between the groups. The mean total hospital length of stay (LOS) was longer for Group 1 versus 2; however, the mean postprocedure LOS was the same between the groups. During follow‐up, there was no difference in the cardiac readmission rate over a 1‐year period (four vs seven patients in Group 1 vs 2, respectively; P = 0.8). Long‐term follow‐up revealed similar mortality rates in both groups. (18 patients in Group 1, and 21 patients in Group 2; P = 0.8).

Conclusions

Inappropriate shocks due to lead noise do not seem to predispose to a worse clinical outcome after ICD lead extraction.
An Observational Study of Abstracts Presented at the American College of Veterinary Surgeon Annual Meetings (2001–2008) and Their Subsequent Full‐Text Publication
Authors: Meyers Katherine E. , Lindem Margaret J. , Giuffrida Michelle A.
Published: May 2016

Objective

To determine the frequency of abstracts presented at American College of Veterinary Surgeons (ACVS) meetings from 2001 to 2008 that were published as complete articles, to identify abstract characteristics associated with final full‐text publication, and to examine consistency of information between abstracts and final full‐text publications.

Study Design

Observational bibliographic study.

Methods

Abstracts were retrieved from published proceedings. Published articles were retrieved from bibliographic databases. Features of abstract and article authorship, design, and content were recorded. Regression analysis identified abstract features associated with article publication, and evaluated consistency between abstracts and final publications.

Results

Seven hundred eighty‐two of 1078 (73%) abstracts were published as complete articles. Median time to publication was 1 year; 90% were published within 3 years. Abstracts originating from academic institutions were published more often than abstracts from practice or industry sites (odds ratio 2.61, 95% confidence interval 1.68–4.05). Compared to their conference abstracts, 49% of articles contained major inconsistences including changes in study design, interventions, outcomes, sample size, and results. For each year elapsed between presentation and publication, the odds of major inconsistency increased 2.4 times (odds ratio 2.36, 95% confidence interval 1.57–3.55) for retrospective studies and 1.4 times (odds ratio 1.35, 95% confidence interval 1.17–1.56) for other study designs. Changes in study title and authorship were frequent, particularly in publications that contained major inconsistencies.

Conclusion

ACVS abstracts were promptly and reliably published, but final full‐text publications often differed substantially from the original abstracts.
Inner City East – One Christchurch community’s story
Authors: Kane Raylee , Smith Jenny
Published: May 2016

The process of recovery for communities adversely affected by natural disaster is often conceived as a steady journey back to what was. Experience in Christchurch following the 2010/2011 sequence of disastrous earthquakes tells us that recovery is actually very complex and will, in large part, depend upon the strengths of the community before the disaster. This article is the story so far, of one inner city community, how it responded to the disaster and how it is participating in its own recovery
Registration: Ten years on within a non-government organisation
Authors: Smith Pam
Published: May 2016

The Social Workers Registration Act 2003 has now been part of legislation for 10 years. This remains a voluntary registration and has been embraced by some organisations but not others. Whether social workers wish to become registered has been left to them and their employers to decide, as mandatory registration has not yet been legislated. This article considers the implementation of registration on Family Works Southland, the Child and Family Support Service of Presbyterian Support Southland, a non-government organisation. As a team leader within the agency, I have included my observations along with discussions held with staff and input from the manager and director.
A Kaupapa Māori supervision context – cultural and professional
Authors: Elkington Jacquelyn
Published: May 2016

This article affirms an indigenous perspective for Māori practitioners of professional supervision in the social sciences, particularly in the practice of Kaupapa Māori supervision. Definitions of supervision are discussed, Codes of Ethics are analysed and are provided a cultural response. Key problem areas of the current cultural supervision situation are identified and an analysis of those areas is deconstructed by asking questions of existing power relations within the sector. Accountability, representation, initiation, benefits and legitimization (Bishop & Glynn, 1990) are the topics under scrutiny. The article reports on a reconstruction of some key solution areas as researched in a PhD study of Kaupapa Māori supervision, completed in 2013.
Cross-disciplinary supervision amongst social workers in Aotearoa New Zealand
Authors: Hutchings Jo , Cooper Lareen , O'Donoghue Kieran
Published: May 2016

Cross-disciplinary supervision is occurring amongst social workers in Aotearoa New Zealand and it is regarded positively. However, the findings of this research involving 54 social workers who are members of the Aotearoa New Zealand Association of Social Workers (ANZASW) indicates there is a) no clear understanding of what constitutes cross-disciplinary supervision; b) potential for issues to arise and c) a need for guidelines. The results are discussed in terms of developing knowledge, practice competence and accountability in relation to the practice of cross-disciplinary supervision and a framework for cross disciplinary supervision is presented.
Spirituality and social work: Introducing a spiritual dimension into social work education and practice
Authors: Phillips Carol
Published: May 2016

Against a background of growing international interest in the place of spirituality in social work education and practice, this paper describes a qualitative study of the spiritual expe- riences of non-Māori social work students at Te Wānanga o Aotearoa, and the application of spirituality to their practice as social workers. The study found that both the programme and Wānanga environment enhanced and deepened participants’ own spirituality and flowed through into their practice. Elements of the Wānanga programme which contributed to the students’ spiritual development are identified, along with a discussion of the influence of the bicultural nature of the programme and take pū on their practice.
Twenty-five years of adult adoption in New Zealand 1985-2010: An overview of adult adoption since the implementation of the Adult Adoption Information Act 1985
Authors: Aburn Anne
Published: May 2016

When the Adult Adoption Information Act 1985 was introduced it enabled many people who were adopted to reclaim their original identities. The Act also enabled parents who had relinquished children for adoption to reunite with them. The Act made provision for 24 dedicated social workers known as Adult Adoption Information Officers to be appointed throughout New Zealand. This article, which is a personal reflection on how the Act was implemented and the changes in adoption practice over 25 years, was originally written in 2010 for all Ministry of Social Development Adoption Social Workers.

Tiromoana and Taranaki House: A tale of their times
Authors: Staniforth Barbara
Published: May 2016

The overall history of social work education in Aotearoa New Zealand has been well documented by authors such as McCreary (1971a,b), Nash (1998) and Cranna (1989). Tiromoana and Taranaki House social work residential training institutions were set up by the Education Department, Child Welfare Division to meet a gap in social work training in the country in the 1960s and 70s. These programmes, which were at times contentious, appeared to be unique and particular to their time, place and context in Aotearoa New Zealand. This article provides some history and participant recollections about Tiromoana (Porirua) and Taranaki House (Auckland) for social work’s historical record. This article attempts to piece together various sources, including recent interviews, and to weave together some of the facts and stories of these two institutions.
Animals and social work: An emerging field of practice for Aotearoa New Zealand
Authors: Walker Peter , Aimers Jenny , Perry Claire
Published: May 2016

Social work is traditionally human-centered in practice, even though for many the bond between humans and animals is the most fundamental of daily-lived experiences. The intent of this paper is to reflect on the predominant humanistic basis of social work and to consider the growing evidence for developing a wider perspective to incorporate the human-animal connection into social work practice. Joanne Emmens (2007:9) observes that the human-animal bond is considered by some as ‘…too mainstream (in the sense of being lightweight, cliché or sentimental), or as not mainstream enough…as substantial material worthy of study.’ In this article we argue that the human-animal bond is neither sentimental nor fringe and that our attitudes toward this relationship is based on a construction of western thought. To support this we offer a review of literature that provides evidence of good practice that can move social work beyond a purely humanistic approach to a more holistic view resulting in a more comprehensive toolkit for practice. We explore the literature and practice surrounding the place of animals in social work, both in New Zealand and internationally. In addition, we identify some of the ways the human-animal bond is currently utilised in rehabilitation, therapy, as animal assistants and as an indicator of domestic violence within New Zealand. We argue that this area of research and practice is highly relevant for social work as evidence-based practice. The paper con- cludes by offering some suggestions for discussion within the social work profession, and considerations for social work educators, researchers and theorists.
Thinking of moving overseas? Reflections from a social worker’s journey of migration to New Zealand
Authors: Troughton Helen Barker
Published: May 2016

This is one woman’s story of living through times of significant change. These changes include migration overseas and entering the part-time workforce after becoming a mother in later life. It describes the surfacing of personal questions, self-reflections and actions she found helpful as she used the new experiences to reshape her identity and become more effective personally and as a social worker. Through these times she realised a desire to live more meaningfully in the midst of change, loss and uncertainty. She looks at the nature of resilience and how this can be harnessed to become stronger at home and at work. She shares her personal journey to offer hope to herself and others on a similar journey, including suggestions of ways to embrace change. The main voice is the migrant asking questions and pointing toward snippets of light she hopes will help others.

Toward equal participation: An auto-ethnography of facilitating consultations in the refugee sector
Authors: Elliot Sue
Published: May 2016

This article uses an auto-ethnographic approach to exploring how one positions oneself as a facilitator in a layered and power-laden context in the refugee sector in New Zealand to ensure just and collaborative negotiations. It reflects on my facilitation practice based during a series of annual consultations between UNHCR, NGOs and refugee community representatives over a period of five years. The article begins by providing a brief overview of the New Zealand refugee system. This is followed by a review of relevant literature on the role of the facilitator and the role of facilitation within community development, an acknowledged field of social work. Reflections on facilitation practice within an ethnically diverse situation makes up the bulk of the article, which is written from the perspective of a Pakeha woman who has worked in the refugee sector for nearly 35 years, most recently in community development and capacity building of refugee-based organisations. This paper adopts a relatively descriptive style to a personal reflection on facilitating large consultations in the refugee sector in New Zealand. For ease of reading, the term refugee is used throughout, although the consultations focus on both refugee and asylum issues. As presented here, my reflexive analysis is interwoven with research and literature on facilitation and reflects who I am and what I value, in a myriad of tacit and overt ways. It focuses on the facilitation process and the role of the facilitator rather than on the outcomes of the consultations. I have deliberately focused on my own story as I consider this is the story I can ethically tell.
A review of a primary mental health service 10 years on
Authors: Taylor Sarah
Published: May 2016

The past 10 years have seen a shift in mental health care in Aotearoa New Zealand towards early intervention and treatment at a primary care level providing a range of levels of mental health interventions in a variety of settings. Previously specialist mental health care had been the responsibility of community mental health teams and secondary service inpatient care which provided care for people with severe mental illness (3% of the population). In this article, I look at the move towards the provision of primary mental health care. I describe and review the Mental Health Brief Intervention Service in South Canterbury, one of the earliest primary mental health services initiated by the South Canterbury District Health Board, which started in 2005. I present research fi from my Master’s thesis Mental Health Brief Intervention – does it work? An evaluation of practice, and discuss how the Mental Health Brief Intervention Service has made a positive change for general practitioners, the client, the interface with other services including secondary mental health services and service delivery in general. Forms of consumer feedback are discussed along with the changes in the service over the last 10 years. It is written by myself, a social worker, who played an integral part in initiating and establishing the service and continues to have an active role as a clinician within the Mental Health Brief Intervention Service. This article is written to provide social workers with an overview of the establishment of the Mental Health Brief Intervention Service and the impact on service delivery. The role of the social worker is discussed as is the role of other health professionals within the team.
Comparing public perceptions of social work and social workers’ expectations of the public view
Authors: Staniforth Barbara , Deane Kelsey L. , Beddoe Liz
Published: May 2016

INTRODUCTION: Previous studies have explored public perception of social work and social workers. There is little written about what social workers think about how they, and the profession of social work, are viewed by the public. This article explores the views of a sample of social workers in Aotearoa New Zealand about their beliefs around the public perception of social work and social workers.AIMS: This article aims to explore social worker views on the public perception of social work, and then compares these findings with a previous study which looked at the public perception of social workers.METHODOLOGY: An online survey was conducted with 403 social workers from the Aotearoa New Zealand Association of Social Work, which asked them about their perceptions on how social work and social workers are viewed by the public. The results are then compared to a previous telephone survey, which asked 386 members of the public their views on social work and social workers.FINDINGS: Results demonstrate that the social workers generally had a poorer impression of what the public believed in most areas, compared to what the public had indicated in the prior study.CONCLUSION: Social workers, social work professional bodies and social work educators need to be proactive in promoting accurate information about social work and what social workers do.
Consent, coercion and autonomy: Underage sex work in Aotearoa New Zealand
Authors: Thorburn Natalie
Published: May 2016

INTRODUCTION: Adolescents’ involvement in sex work in New Zealand has been associated with a range of adverse effects on physical, psychological, and social well-being, and is framed by domestic legislation and international obligations.AIM: The study aimed to ascertain the nature of adolescents’ experiences of sex work, and how their current and past environments impacted on their understanding of their involvement in sex work.METHODS: Semi-structured interviews were used with a sample of eight adolescents aged 16-20 who became involved with sex work between ages 12 and 16.FINDINGS: The study found that participants’ exposure to physical and sexual abuse in childhood had informed their internal working models of normative gendered behaviour. These models were then reinforced by exposure to the gendered power differential inherent in the sex work sub-culture. Participants experienced sexual experiences as being solely dictated by men, and frequently normalised transgressions against physical and/or sexual integrity.CONCLUSION: The prevalence and acceptance of gendered harm among this population group indicates the need to appropriately address vulnerable adolescents’ abuse histories, challenge restrictive conceptions of gender, and actively combat the pervasive presence of gendered violence and inequality among this population group.
Bi-culturalism and accountability: Fundamental changes in social work practice in Aotearoa New Zealand 1984 – 1990
Authors: Fraser Sarah , Briggs Lynne
Published: May 2016

A number of key events took place in the history of the Aotearoa New Zealand Association of Social Workers (ANZASW) in the mid-1980s and early 1990s. This article explores critical developments and debates in the lead up to the 1986 Turangawaewae conference at which the bi-cultural structure of the Association first emerged. The proceedings of the conference itself are examined and the subsequent establishment of a unique system of accountability for ANZASW members discussed. These events are considered significant in the shaping of the Association’s current structure, bi-lingual Code of Ethics (ANZASW, 2015), its competency assessment processes and in its contribution to the era of professional registration.While it is impossible to clearly delineate a beginning point, the article picks up the Association’s story in 1984. It is told from the perspective of the first two Manuhiri Caucus Presidents, Sarah Fraser (1986-1988) and Lynne Briggs (1988 – 1990), and gives voice to some of the participants involved through reference to documents and communications of the time. Other than the points at which the histories of the Manuhiri (later renamed as Tau Iwi) and Tangata Whenua (later renamed as Tangata Whenua Takawaenga o Aotearoa) caucuses intersect, it is the authors’ view that the important and ground breaking history of the Tangata Whenua Caucus is not theirs to relate.
Estimation of biological parameters of marine organisms using linear and nonlinear acoustic scattering model-based inversion methods
Authors: Chu Dezhang , Lawson Gareth L. , Wiebe Peter H.
Published: May 2016

The linear inversion commonly used in fisheries and zooplankton acoustics assumes a constant inversion kernel and ignores the uncertainties associated with the shape and behavior of the scattering targets, as well as other relevant animal parameters. Here, errors of the linear inversion due to uncertainty associated with the inversion kernel are quantified. A scattering model-based nonlinear inversion method is presented that takes into account the nonlinearity of the inverse problem and is able to estimate simultaneously animal abundance and the parameters associated with the scattering model inherent to the kernel. It uses sophisticated scattering models to estimate first, the abundance, and second, the relevant shape and behavioral parameters of the target organisms. Numerical simulations demonstrate that the abundance, size, and behavior (tilt angle) parameters of marine animals (fish or zooplankton) can be accurately inferred from the inversion by using multi-frequency acoustic data. The influence of the singularity and uncertainty in the inversion kernel on the inversion results can be mitigated by examining the singular values for linear inverse problems and employing a non-linear inversion involving a scattering model-based kernel.
Effects of speech style, room acoustics, and vocal fatigue on vocal effort
Authors: Bottalico Pasquale , Graetzer Simone , Hunter Eric J.
Published: May 2016

Vocal effort is a physiological measure that accounts for changes in voice production as vocal loading increases. It has been quantified in terms of sound pressure level (SPL). This study investigates how vocal effort is affected by speaking style, room acoustics, and short-term vocal fatigue. Twenty subjects were recorded while reading a text at normal and loud volumes in anechoic, semi-reverberant, and reverberant rooms in the presence of classroom babble noise. The acoustics in each environment were modified by creating a strong first reflection in the talker position. After each task, the subjects answered questions addressing their perception of the vocal effort, comfort, control, and clarity of their own voice. Variation in SPL for each subject was measured per task. It was found that SPL and self-reported effort increased in the loud style and decreased when the reflective panels were present and when reverberation time increased. Self-reported comfort and control decreased in the loud style, while self-reported clarity increased when panels were present. The lowest magnitude of vocal fatigue was experienced in the semi-reverberant room. The results indicate that early reflections may be used to reduce vocal effort without modifying reverberation time.

Emerging solutions to the water challenges of an urbanizing world
Authors: Larsen Tove A. , Hoffmann Sabine , Lüthi Christoph , Truffer Bernhard , Maurer Max
Published: May 2016

The top priorities for urban water sustainability include the provision of safe drinking water, wastewater handling for public health, and protection against flooding. However, rapidly aging infrastructure, population growth, and increasing urbanization call into question current urban water management strategies, especially in the fast-growing urban areas in Asia and Africa. We review innovative approaches in urban water management with the potential to provide locally adapted, resource-efficient alternative solutions. Promising examples include new concepts for stormwater drainage, increased water productivity, distributed or on-site treatment of wastewater, source separation of human waste, and institutional and organizational reforms. We conclude that there is an urgent need for major transdisciplinary efforts in research, policy, and practice to develop alternatives with implications for cities and aquatic ecosystems alike.

The ecological future of cities
Authors: McDonnell Mark J. , MacGregor-Fors Ian
Published: May 2016

The discipline of urban ecology arose in the 1990s, primarily motivated by a widespread interest in documenting the distribution and abundance of animals and plants in cities. Today, urban ecologists have greatly expanded their scope of study to include ecological and socioeconomic processes, urban management, planning, and design, with the goal of addressing issues of sustainability, environmental quality, and human well-being within cities and towns. As the global pace of urbanization continues to intensify, urban ecology provides the ecological and social data, as well as the principles, concepts and tools, to create livable cities.

Building functional cities
Authors: Henderson J. Vernon , Venables Anthony J. , Regan Tanner , Samsonov Ilia
Published: May 2016

The literature views many African cities as dysfunctional with a hodgepodge of land uses and poor “connectivity.” One driver of inefficient land uses is construction decisions for highly durable buildings made under weak institutions. In a novel approach, we model the dynamics of urban land use with both formal and slum dwellings and ongoing urban redevelopment to higher building heights in the formal sector as a city grows. We analyze the evolution of Nairobi using a unique high–spatial resolution data set. The analysis suggests insufficient building volume through most of the city and large slum areas with low housing volumes near the center, where corrupted institutions deter conversion to formal sector usage.

Filling the gaps between model predictions and their prerequisites in electric dipole moments
Authors: Fukuyama Takeshi , Asahi Koichiro
Published: May 2016

We clarify the conditions or assumptions under which theoretical predictions of various models beyond the standard model give mainly in electric dipole moments. The correct interpretation of those conditions seems to be indispensable to the refinements of model building as well as to the mutual reliance in experimental and theoretical communities. The connections of these analyses to the recent experimental results at the LHC and the other places are also discussed.
THE IMPACT OF ICT USAGE ON COLLABORATIVE PRODUCT INNOVATION PERFORMANCE
Authors: SILVA CHATHURANI , MATHRANI SANJAY , JAYAMAHA NIHAL
Published: May 2016

Manufacturers are increasingly adopting collaborative product development (CPD) to achieve competitive advantage through joint synergies in introducing new products. Partners involved in CPD may be external such as suppliers and customers or internal cross-functional teams. As the number of dispersed partners increases, substantial rises in the use of information and communication technology (ICT) are evidenced in firms. Since most ICT implementations cost significantly to firms, uncovering a detailed picture of the effect of ICT usage on CPD performance would be immensely useful. Drawing on the relational resource-based view (RRBV), this study explores ICT impact on CPD performance comprising project performance and collaboration performance. Data collected from 244 collaborative product innovation projects were used. The study reveals positive direct and indirect impact of overall ICT usage on new product quality, commercial success, and time performance, through collaboration performance. The observed impact of three ICT usage aspects (frequency, proficiency, and intensity) and individual ICT types significantly contribute to extant literature while providing useful implications to product development practitioners.
Synthesis of Titanium Oxycarbide through Carbothermal Reduction of Titanium Dioxide Nanoparticles and Renewable Biopolymers
Authors: Flach Joshua Paul , Figueiredo de Lima Paulo Henrique , Sparks Joshua Craig , Islam Monsur , Martinez-Duarte Rodrigo
Published: May 2016

The goal of this is study is to explore the feasibility of a sustainable method of titanium oxycarbide synthesis through carbothermal reduction of a biopolymer composite. The reaction was studied at different temperatures in vacuum environments and at multiple TiO2:C ratios in order to determine how these parameters affect the formation of titanium oxycarbide. The results indicate that both the heat treatment and the carbon ratios have a significant impact on the O/C ratio, and therefore, molecular composition and crystal structure of the titanium oxycarbide. The use of renewable biopolymers as a carbon source in the synthesis of oxycarbide can serve as an inexpensive, yet effective alternative to petroleum based sources.
Fabrication of Biocompatible Hollow Microneedles Using the C-MEMS Process for Transdermal Drug Delivery
Authors: Pramanick Bidhan , Martinez-Chapa Sergio Omar , Madou Marc J
Published: May 2016

Transdermal drug delivery using microneedles is a minimally invasive procedure which causes little or no pain. We present a novel method for fabricating microneedles using the Carbon-MEMS (C-MEMS) process. The fabrication of an array of hollow microneedles combining UV photolithography and carbonization of a polymer precursor is demonstrated. The shrinkage of the SU-8 microneedles during pyrolysis was analyzed and the pyrolyzed carbon needle structures were characterized using Raman spectroscopy to determine the extent of sp2 vs sp3 carbon hybridization. Using energy dispersive x-ray spectroscopy we also analyzed the chemical composition of the microneedles. We report here for the very first time the fabrication of glassy carbon hollow microneedles.
Assessing the Advantages of Using Square Wave Signals for Particle Trapping in Carbon-Electrode Dielectrophoresis
Authors: Contreras Dávila Guillermo , Gómez-Quiñones José I. , Perez-Gonzalez Victor Hugo , Martinez-Duarte Rodrigo
Published: May 2016

Here we present an improvement on the trapping efficiency of 3D carbon electrode Dielectrophoresis (carbonDEP) by using alternative signal geometries to the more traditional sine used to stimulate the electrodes. In particular, a square waveform is used. Theoretical analysis was based on the Root Mean Square (RMS) values and the Fourier Series Expansion of these signals. Computational modeling was performed to calculate the DEP force generated by the two signal waveforms and allowed for direct comparison. The trapping efficiency between square and sine signals was then determined experimentally. Given the same experiment characteristics, the use of square signals allows for an improvement in the efficiency when trapping polystyrene particles against a flow.

This paper describes the theoretical and practical basis for obtaining information about shallow buried interfaces, subsurface compositional variations, and electrical potential variations with SPMs. Three techniques are discussed: scanning microwave microscopy (SMM) to image the capacitance of buried metal lines, scanning Kelvin force microscopy (SKFM) to image the potential of buried metal lines, and electric force microscopy (EFM) phase imaging to see buried interface surface roughness. COMSOL simulations of the SMM resonator response to small variations in tip-sample capacitance, explaining the contrast reversal phenomena, are described. SKFM and EFM images of NIST designed potential variation test structures show the potential of each technique for buried interface characterization.

Cu-ion-migration-induced the porous low-k dielectric breakdown was studied in alternating polarity-bias conditions using a metal–insulator–metal (MIM) capacitor with Cu as a top metal electrode. The experimental results indicated that Cu ions migrate into a dielectric film under a positive polarity stress, leading to a shorter time to failure (TTF). Additionally, the TTF obtained in the alternating-polarity test increased with decreasing the stressing frequency, indicating that the backward migration of Cu ions during the reverse-bias stress. When the frequency is decreased to 10-2 Hz, the measured TTFs were higher as compared to a direct-current (DC) stress condition. Under Cu-ion-recovery case, the electric-field acceleration factor for porous low-k dielectric film breakdown tends to increase. Meanwhile, this Cu backward migration effect is effective as the stressing time in the negative polarity is larger than 0.1 s.
Numerical Investigation on Atomic Migration Effect on Thermal Conductivity of Al/Cu Interface Structures in Electronic Interconnection Packaging
Authors: Zhang Liqiang , Ge Daohan
Published: May 2016

The thermal conductivity of Al/Cu interface structures in electronic interconnection packaging is studied based on NEMD method by considering the atomic migration under different temperatures in this work. An interesting phenomenon is discovered that the thermal conductivity of Al/Cu interface increases with the increasing of atomic migration and diffusion from 400K to 600K; However, it decreases when the temperature is over 600K. It may be caused by the recrystallization of aluminum atoms, which lead to the interface thermal resistance increasing. It means that the heat transfer efficiency can be artificially controlled by heat treatment in appropriate temperature range. This investigation is helpful for understanding the interface heat transfer mechanism of the interface structures, which also implies a potential method for the analysis of the interface thermal performance and design of the interface in electronic packaging micro/nano-manufacturing.

The inherently disordered nature of amorphous silicon plays a major role in determining their fundamental characteristic. The electrical and optical properties of B- doped hydrogentated amorphous silicon (a-Si:H) thin films deposited using RF-PECVD have been studied. The diborane and hydrogen flow rates are changed during the film deposition. The incorporation of B-dopants and hydrogen on the a-Si band gap, resistivity and index of refraction are carried out using UV/VIS/INR spectrophotometer, hall measurements and variable angle ellipsometry, respectively. The findings of the present work explain the causal relationship between the atomic structures, the chemical environment of amorphous silicon, and the growth condition in changing the electrical and optical characteristic of a-Si:H. Furthermore, by understanding the structural hole trapping defects and optimizing the growth condition a high performance a-Si based devices can be achieved.

Ternary rare earth oxides are promising candidates for future gate oxides. Therefore GdScO3 and LaLuO3 were investigated with regard to their suitability as gate dielectric. The layers were deposited by pulsed laser deposition and the crystal structure, stoichiometry, layer roughness and band gap were investigated. GdScO3 can be grown hexagonal and amorphous and LaLuO3 can be grown hexagonal, orthorhombic and amorphous. All investigated layers revealed smooth surfaces, exhibited band gaps higher than 5 eV and a permittivity higher than 20. These results show that GdScO3 and also LaLuO3 are promising candidates as a future gate dielectric based on nitride semiconductor devices.

Self-assembled nano-crystalline BaTiO3 films on stainless steel foil substrates, were grown by the water based Streaming Process for Electrodeless Electrochemical Deposition (SPEED). SPEED is an aqueous process that deposits self-assembled nano-crystalline inorganic thin films over large areas, without a vacuum, providing a scalable and manufacturing friendly process to fabricate durable films. The morphology of the ~1 µm thick films comprises single crystals of micron dimensions imbedded in a matrix of nanocrystals. XRD confirms presence of BaTiO3 crystals of hexagonal phase for samples annealed at 500 C. Subsequent annealing at 600 C transforms the film to the cubic phase. Potential applications include dielectric layers, capacitors, waveguides, ferroelectric RAM, pyroelectric infrared detectors, and phosphors. Characterization of infrared pyroelectric response at 10 µm wavelength shows an initially good sensitivity that reversibly decays over a period of days due to water vapor absorption. A short-lived photo-response due to poling of the hydrated sample is also observed.

We have developed pixel-parallel CMOS image sensors with 16-bit A/D converters (ADCs) by 3-D integration of silicon-on-insulator (SOI) layers. Hybrid bonding of Au electrodes embedded in a SiO2 surface is suitable for a high-density interconnection to deliver pixel-parallel operation of the sensor. Photodiodes, ADCs, and counters are prepared on two SOI layers, and they are connected in each pixel to develop the 128 × 96 pixel-parallel sensors. We have demonstrated successful operation of video imaging with 16-bit digital output and a wide dynamic range of 96 dB, showing the feasibility of high performance 3-D integrated devices.

Published: May 2016

The memcapacitive characteristics in metal-oxide-semiconductor (MOS) capacitor structures consisting of reactive electrode (Mo, Al) and hafnium oxide (HfOX) on n-type Si and indium-gallium-zinc-oxide (IGZO) semiconductor were investigated. The capacitance-voltage (C-V) curves exhibited sequentially changing capacitance as repeating the voltage sweeps in an analog fashion. The saturation capacitance was decreased as repeatedly applying +V, while the depletion capacitance was barely changed at repeated –V application. The capacitance-time (C-t) curves disclosed the same tendency of capacitance change. On the other hand, the MOS structure with inert electrode (Pt) did not show the capacitance change. These memcapacitive behaviors were induced by the migration of oxygen ions between reactive electrodes (Mo, Al) and HfOX, modulating the permittivity and effective capacitor area. These results demonstrated the memcapacitive characteristics in MOS structure through voltage-driven oxygen migration, which could be applied to memory, logic, and neuromorphic devices.

In this Letter, high-temperature ion implantation and low-temperature microwave annealing were employed to achieve maximum n-type active concentration, which can be fully activated in germanium. To use the characteristic of microwave annealing more effectively, two-step microwave annealing was also employed. In the first step annealing, a high-power (1200 W; 425 °C) microwave was used to achieve solid-state epitaxial regrowth (SPER) and enhance microwave absorption. In the second step of annealing, unlike in conventional thermal annealing, which requires a higher energy to activate the dopant, a low-power (900W;375 °C) microwave was used to achieve lowest sheet resistance 78Ω/□ and maximum active concentration 1.025×1020 P/cm3, which close to its solid solubility limit of 2×1020 P/cm3.

Shallow trench isolation (STI) divot shape control is always one of most key logic processes in semiconductor fabrication. Conventional wet chemical treatment easily causes deep divot and results in transistor kink effect of drain current (Id) v.s. gate voltage (Vg) relation curve. Gas phase chemical etching method can reduce divot level around 55% compared with conventional wet batch type dilute HF (DHF) etching. This study indicated that divot formation is highly correlated to etching surface geometry, chemical boundary layer thickness and chemical flow speed. By etching method selection and parameter adjustment, divot can be well controlled in logic process.
