Adhesion/Diffusion Barrier Layers for Copper Integration: Carbon-Silicon Polymer Films and Tantalum Substrates

Adhesion/Diffusion Barrier Layers for Copper Integration: Carbon-Silicon Polymer Films and Tantalum Substrates

Date: December 1999
Creator: Chen, Li
Description: The Semiconductor Industry Association (SIA) has identified the integration of copper (Cu) with low-dielectric-constant (low-k) materials as a critical goal for future interconnect architectures. A fundamental understanding of the chemical interaction of Cu with various substrates, including diffusion barriers and adhesion promoters, is essential to achieve this goal. The objective of this research is to develop novel organic polymers as Cu/low-k interfacial layers and to investigate popular barrier candidates, such as clean and modified tantalum (Ta) substrates. Carbon-silicon (C-Si) polymeric films have been formed by electron beam bombardment or ultraviolet (UV) radiation of molecularly adsorbed vinyl silane precursors on metal substrates under ultra-high vacuum (UHV) conditions. Temperature programmed desorption (TPD) studies show that polymerization is via the vinyl groups, while Auger electron spectroscopy (AES) results show that the polymerized films have compositions similar to the precursors. Films derived from vinyltrimethyl silane (VTMS) are adherent and stable on Ta substrates until 1100 K. Diffusion of deposited Cu overlayers is not observed below 800 K, with dewetting occurred only above 400 K. Hexafluorobenzene moieties can also be incorporated into the growing film with good thermal stability. Studies on the Ta substrates demonstrate that even sub-monolayer coverages of oxygen or carbide on polycrystalline ...

Adlerian Life Style and the Myers-Briggs Type Indicator

Adlerian Life Style and the Myers-Briggs Type Indicator

Date: May 1993
Creator: Doss, Carol Rose
Description: The possibility of a relationship between Adlerian life style, as measured by the Life Style Personality Inventory (LSPI), and the Myers-Briggs Type Indicator (MBTI) was examined by this research. The goal of this study was to clarify the relationship between these instruments to broaden the applicability of both instruments for both research and clinical endeavors. Life style is a concept which is vital to therapeutic intervention from an Adlerian frame of reference. Assessment of life style typically involves lengthy therapist interviews. Both the LSPI and the MBTI are questionnaires designed to measure personality variables. The 117 subjects for this study were solicited from individuals seeking counseling from an urban community counseling center. The individuals served by this agency are primarily those diagnosed with Adjustment Disorders. The LSPI and the MBTI were administered individually to each subject. Means and standard deviations were computed for the seven LSPI themes and the MBTI total. Due to a lack of research support for Theme 4 by the LSPI author, the data for this theme were disregarded. The same research indicated a strong bipolar relationship for Themes 7 and 8 (Displaying Inadequacy and Social Interest), which prompted the inclusion of Theme 8 in subsequent data ...

Adlerian Personality Priorities of Siblings of Individuals with Tourette Syndrome

Adlerian Personality Priorities of Siblings of Individuals with Tourette Syndrome

Date: August 1998
Creator: Sims, Deanna
Description: This study was designed to examine Adlerian personality priorities of siblings of individuals with Tourette Syndrome (TS). This study aimed to investigate whether a difference exists between TS siblings and siblings of those without disabilities on variables related to personality priorities. It was hypothesized that TS siblings would score significantly higher than the control group on the superiority and pleasing personality priorities and significantly lower on the comfort and control personality priorities. Both of the hypotheses were rejected. First, no significant difference was found between TS siblings and the control group on the superiority and pleasing personality priorities. Second, no significant difference was found between TS siblings and the control group on the comfort personality priority, and TS siblings scored significantly higher than the control group on the control personality priority.

The Administration of Auxiliary Services in Texas Public Universities: Analysis and Proposed Integrated Model

The Administration of Auxiliary Services in Texas Public Universities: Analysis and Proposed Integrated Model

Date: May 1994
Creator: Yarbrough, Marianne (Marianne June)
Description: The problem of this study was to develop a model for the administration of auxiliary enterprises in Texas higher education as a cooperative effort of administrators and input from other sources. The purposes were to determine which administrators currently have the responsibility for the management of auxiliary services, to evaluate the correlation between the type of administrator and the concern for fiscal and student needs, to identify problems and opportunities for useful administration, and to develop a model integrating the strengths of each administrator and the implementation of new ideas to improve auxiliary enterprise management. A survey instrument consisting of three types of questions was mailed to both Vice Presidents of Fiscal Affairs and Student Affairs at all 26 four-year public institutions in Texas. Part I questions were informational, designed to determine who administers auxiliary services. Part II consisted of 20 questions on a Likert scale to obtain both opinions on the theories of the research, and specialized knowledge of the administrators. Part III was free response to solicit ideas from the administrators for the construction of the model. Paired t-tests were performed to determine knowledge strengths of the administrators. All other information was presented in frequency tables or narrative ...

Adolescent Pregnancy: Voices Heard in the Everyday Lives of Pregnant Teenagers

Date: December 1995
Creator: Oviedo, Sonia
Description: The purpose of this study is to examine the problems that pregnant teenagers encounter at school and at home while they are trying to complete their high school education. Data were collected by in-depth interviews. Twenty pregnant adolescents, who were between the ages of 15 through 18, and were participants in a special teen pregnancy program were interviewed. The major findings in this study included the respondents': 1) unstable family life histories, 2) denial that they were pregnant, 3) need for self-identity as an adult, 4) conflict with parents and 5) motivation to complete their high school education. This study points to the need for more research on the problems that pregnant adolescents encounter in their everyday lives.

Adult Christian Education for Baby Boomers: a Descriptive Case Study of Three American Churches

Date: August 1994
Creator: Donahue, William P. (William Paul)
Description: American churches seeking to assimilate baby boomers are struggling to meet the adult educational needs of this group. To determine what models of church-based adult education are used to meet the educational needs of this group, three large, growing American churches known for attracting boomers were identified as sites for research. A qualitative case study research design was used and results were compared using cross-case analysis. Initial data collection included a three-day visit at each church. Data were collected in three phases: Phase One consisted of personal interviews with staff and lay leaders; Phase Two focused on observation of adult education events which took place during the visitation period; Phase Three involved gathering materials that described adult education programs. To optimize the reliability and accuracy of the findings data were subjected to examination by peers, collection methods were applied consistently in each research phase, follow-up contacts were made with each church to verify observations and findings, and case records were created for each site. Eleven categories were selected and the data were presented by category. Within each category, data were delineated and organized into three areas: trends among the churches, noteworthy comments about individual programs, and comparison to the literature ...
