    Si(100)–SiO2 interface properties following rapid thermal processing (2001)

    Notes: An experimental examination of the properties of the Si(100)–SiO2 interface measured following rapid thermal processing (RTP) is presented. The interface properties have been examined using high frequency and quasi-static capacitance-voltage (CV) analysis of metal-oxide-silicon (MOS) capacitor structures immediately following either rapid thermal oxidation (RTO) or rapid thermal annealing (RTA). The experimental results reveal a characteristic peak in the CV response measured following dry RTO and RTA (T〉800 °C), as the Fermi level at the Si(100)–SiO2 interface approaches the conduction band edge. Analysis of the QSCV responses reveals a high interface state density across the energy gap following dry RTO and RTA processing, with a characteristic peak density in the range 5.5×1012 to 1.7×1013 cm−2 eV−1 located at approximately 0.85–0.88 eV above the valence band edge. When the background density of states for a hydrogen-passivated interface is subtracted, another peak of lower density (3×1012 to 7×1012 cm−2 eV−1) is observed at approximately 0.25–0.33 eV above the valence band edge. The experimental results point to a common interface state defect present after processes involving rapid cooling (101–102 °C/s) from a temperature of 800 °C or above, in a hydrogen free ambient. This work demonstrates that the interface states measured following RTP (T〉800 °C) are the net contribution of the Pb0/Pb1 silicon dangling bond defects for the oxidized Si(100) orientation. An important conclusion arising from this work is that the primary effect of an RTA in nitrogen (600–1050 °C) is to cause hydrogen desorption from pre-existing Pb0/Pb1 silicon dangling bond defects. The implications of this work to the study of the Si–SiO2 interface, and the technological implications for silicon based MOS processes, are briefly discussed. The significance of these new results to thin oxide growth and optimization by RTO are also considered. © 2001 American Institute of Physics.

    Factors affecting family-centred service delivery for children with disabilities (2003)

    Notes: Background  The provision of family-centred services (FCS) emphasizes a partnership between parents and service providers so that families are involved in every aspect of services for their child. There is evidence that providing FCS is associated with improvements in parents’ satisfaction with services, decreased parental stress, and positive child outcomes.Methods  The purpose of this study was to examine factors that are most important in determining parent perceptions of the family centredness of care and parent satisfaction with service. A cross-sectional survey was completed by 494 parents, 324 service providers, and 15 CEOs from 16 organizations delivering children's rehabilitation services. Analyses were completed using a structural equation modelling approach.Results  Survey return rates ranged from 77 to 94%. Findings indicate that the principal determinants of parent satisfaction with services are the family-centred culture at the organization and parent perceptions of FCS. Parent satisfaction with services was also influenced by the number of places where services were received and the number of health and development problems experienced by their child.Conclusion  Parent satisfaction with services is strongly influenced by the perception that services are more family centred, fewer places where services were received and fewer health and development problems for their child. Ways in which organizations can improve satisfaction through carrying out family-centred behaviours are discussed.

    Determination of generation lifetime in intrinsic polycrystalline silicon (1989)
    Woodbury, NY : American Institute of Physics (AIP)

    Notes: A simple two-terminal method is described for the determination of generation lifetime in intrinsic polycrystalline silicon suitable for thin-film transistor applications using a metal/SiO2 /polycrystalline silicon/n-type silicon test structure. The method consists of monitoring the high-frequency capacitance of the test structure after the application of a voltage pulse of the correct polarity to cause deep depletion in the n-type substrate. Generation lifetimes of 34 ps to 19 ns are obtained for polycrystalline silicon films of varying grain size.

    Alpha thalassaemia hydrops fetalis in the UK: the importance of screening pregnant women of Chinese, other South East Asian and Mediterranean extraction for alpha thalassaemia trait (1992)

    Notes: Objective Alpha zero (α° or α-1) thalassaemia is an important genetic risk for women originating from Hong Kong, Singapore, Vietnam, Thailand, the Philippines or South China. Cypriots are also at risk. Carriers of α° thalassaemia trait can be detected by routine haemoglobinopathy screening. When a couple are both carriers, in each pregnancy there is a 25% risk that the fetus will have α thalassaemia hydrops fetalis; this is fatal for the fetus and carries serious obstetric and psychological risks for the mother. Most informed couples at risk request prenatal diagnosis and selective abortion. This study investigates the effectiveness of screening, counselling and prenatal diagnosis for α thalassaemia hydrops fetalis in the UK.Design Retrospective analysis of the notes.Subjects 18 couples attending University College Hospital London for prenatal diagnosis of α thalassaemia hydrops fetalis since 1982.Results The study shows underdiagnosis of both α° thalassaemia trait and α thalassaemia hydrops fetalis leading to avoidable stillbirths and complications in pregnancy.Conclusion We recommend early screening for α° thalassaemia trait for all women of Southeast Asian or eastern Mediterranean origin and the offer of prenatal diagnosis when indicated. The diagnosis of α thalassaemia hydrops fetalis should be considered in women of the relevant ethnic origin who have a stillbirth, neonatal death, abnormal ultrasound findings at fetal anomaly scanning (especially a large placenta), or who develop pre-eclampsia.
