Functionalization and characterization of porous low-κ dielectrics.

Description: The incorporation of fluorine into SiO2 has been shown to reduce the dielectric constant of the existing materials by reducing the electrical polarizability. However, the incorporation of fluorine has also been shown to decrease film stability. Therefore, new efforts have been made to find different ways to further decrease the relative dielectric constant value of the existing low-k materials. One way to reduce the dielectric constant is by decreasing its density. This reduces the amount of polarizable materials. A good approach is increasing porosity of the film. Recently, fluorinated silica xerogel films have been identified as potential candidates for applications such as interlayer dielectric materials in CMOS technology. In addition to their low dielectric constants, these films present properties such as low refractive indices, low thermal conductivities, and high surface areas. Another approach to lower k is incorporating lighter atoms such as hydrogen or carbon. Silsesquioxane based materials are among them. However, additional integration issues such as damage to these materials caused by plasma etch, plasma ash, and wet etch processes are yet to be overcome. This dissertation reports the effects of triethoxyfluorosilane-based (TEFS) xerogel films when reacted with silylation agents. TEFS films were employed because they form robust silica networks and exhibit low dielectric constants. However, these films readily absorb moisture. Employing silylation reactions enhances film hydrophobicity and permits possible introduction of this film as an interlayer dielectric material. Also, this work describes the effects of SC-CO2 in combination with silylating agents used to functionalize the damaged surface of the ash-damaged MSQ films. Ashed MSQ films exhibit increased water adsorption and dielectric constants due to the carbon depletion and modification of the properties of the low-k material caused by interaction with plasma species. CO2 is widely used as a supercritical solvent, because of its easily accessible critical point, low ...

Functions of Quotations in Steven Stucky's Oratorio August 4, 1964 and Their Placements within the Context of a Quotation Continuum: Cultural, Commentary, Remembrance, and Unity

Description: The oratorio August 4, 1964 is a twelve-movement work for orchestra, chorus, and four soloists written by Steven Stucky. The premise for the libretto, adapted by Gene Scheer, is the confluence of two events during one day (August 4, 1964) in the life of Lyndon B. Johnson. Although the main idea of the libretto focuses on these two events of this one day, many cultural references of the 1960's in general can be found as well, such as quotations from the well-known song "We Shall Overcome." Stucky borrows from a motet he wrote in 2005 for another quotation source utilized in this oratorio, "O Vos Omnes." My goal in this thesis is to reveal and analyze the many different levels of quotations that exist within August 4, 1964, to explore each quotation's individual function within the oratorio (as a cultural gesture, commentary or remembrance), and to examine the structural coherence that emerges as a result of their use within the oratorio.

Functions of self-injurious thoughts and behaviors within adolescent inpatients.

Description: The primary interest of this investigation concerned the self-injurious thoughts and behaviors (SITBs) of inpatient adolescents. Previous researchers have provided descriptive information regarding either automatic (or intrinsic) and social components using the Self-Injurious Thoughts and Behaviors Interview (SITBI). However, the presence and trends of these components have not firmly been established, suggesting the need to explore this area further. Eighty-two adolescent inpatients were selected and interviewed using the SITBI to evaluate the predictive ability of self-reported self-injurious behavior with regard to social and automatic, negative and positive functions. Results showed that depending on the type of thought or behavior displayed one could discern the motivation behind their actions. Automatic-Negative was seen to have the strongest relationship across all SITB behaviors while Automatic-Negative was not found to be relatively low compared to other SITB behaviors. Both Social-Positive and Social-Negative were found to be present in moderate relationships compared to Automatic in general.

Fundamental Issues in Support Vector Machines

Description: This dissertation considers certain issues in support vector machines (SVMs), including a description of their construction, aspects of certain exponential kernels used in some SVMs, and a presentation of an algorithm that computes the necessary elements of their operation with proof of convergence. In its first section, this dissertation provides a reasonably complete description of SVMs and their theoretical basis, along with a few motivating examples and counterexamples. This section may be used as an accessible, stand-alone introduction to the subject of SVMs for the advanced undergraduate. Its second section provides a proof of the positive-definiteness of a certain useful function here called E and dened as follows: Let V be a complex inner product space. Let N be a function that maps a vector from V to its norm. Let p be a real number between 0 and 2 inclusive and for any in V , let ( be N() raised to the p-th power. Finally, let a be a positive real number. Then E() is exp(()). Although the result is not new (other proofs are known but involve deep properties of stochastic processes) this proof is accessible to advanced undergraduates with a decent grasp of linear algebra. Its final section presents an algorithm by Dr. Kallman (preprint), based on earlier Russian work by B.F. Mitchell, V.F Demyanov, and V.N. Malozemov, and proves its convergence. The section also discusses briefly architectural features of the algorithm expected to result in practical speed increases.

Fundamental Studies of Copper Bimetallic Corrosion in Ultra Large Scale Interconnect Fabrication Process

Description: In this work, copper bimetallic corrosion and inhibition in ultra large scale interconnect fabrication process is explored. Corrosion behavior of physical vapor deposited (PVD) copper on ruthenium on acidic and alkaline solutions was investigated with and without organic inhibitors. Bimetallic corrosion screening experiments were carried out to determine the corrosion rate. Potentiodynamic polarization experiments yielded information on the galvanic couples and also corrosion rates. XPS and FTIR surface analysis gave important information pertaining inhibition mechanism of organic inhibitors. Interestingly copper in contact with ruthenium in cleaning solution led to increased corrosion rate compared to copper in contact with tantalum. On the other hand when cobalt was in contact with copper, cobalt corroded and copper did not. We ascribe this phenomenon to the difference in the standard reduction potentials of the two metals in contact and in such a case a less noble metal will be corroded. The effects of plasma etch gases such as CF4, CF4+O2, C4F8, CH2F2 and SF6 on copper bimetallic corrosion was investigated too in alkaline solution. It was revealed that the type of etching gas plasma chemistry used in Cu interconnect manufacturing process creates copper surface modification which affects corrosion behavior in alkaline solution. The learning from copper bimetallic corrosion studies will be useful in the development of etch and clean formulations that will results in minimum defects and therefore increase the yield and reliability of copper interconnects.

Fundamental Studies of Copper Corrosion in Interconnect Fabrication Process and Spectroscopic Investigation of Low-k Structures

Description: In the first part of this dissertation, copper bimetallic corrosion and its inhibition in cleaning processes involved in interconnect fabrication is explored. In microelectronics fabrication, post chemical mechanical polishing (CMP) cleaning is required to remove organic contaminants and particles left on copper interconnects after the CMP process. Use of cleaning solutions, however, causes serious reliability issues due to corrosion and recession of the interconnects. In this study, different azole compounds are explored and pyrazole is found out to be a potentially superior Cu corrosion inhibitor, compared to the most widely used benzotriazole (BTA), for tetramethyl ammonium hydroxide (TMAH)-based post CMP cleaning solutions at pH 14. Micropattern corrosion screening results and electrochemical impedance spectroscopy (EIS) revealed that 1 mM Pyrazole in 8 wt% TMAH solution inhibits Cu corrosion more effectively than 10 mM benzotriazole (BTA) under same conditions. Moreover, water contact angle measurement results also showed that Pyrazole-treated Cu surfaces are relatively hydrophilic compared to those treated with BTA/TMAH. X-ray photoelectron spectroscopy (XPS) analysis supports Cu-Pyrazole complex formation on the Cu surface. Overall Cu corrosion rate in TMAH-based highly alkaline post CMP cleaning solution is shown to be considerably reduced to less than 1Å/min by addition of 1 mM Pyrazole. In the second part, a novel technique built in-house called multiple internal Reflection Infrared Spectroscopy (MIR-IR) was explored as a characterization tool for characterization of different low-k structures.In leading edge integrated circuit manufacturing, reduction of RC time delay by incorporation of porous ultra low-k interlayer dielectrics into Cu interconnect nanostructure continues to pose major integration challenges. The main challenge is that porous structure renders interlayer dielectrics mechanically weak, chemically unstable and more susceptible to the RIE plasma etching damages. Besides the challenge of handling weak porous ultra low-k materials, a lack of sensitive metrology to guide systematic development of plasma etching, ...

The Fundamental Unity in Brahm's Horn Trio, Op. 40

Description: Different sections or movements of a piece are associated with each other and contain the composer essential thought. A vague affinity of mood and a resembling theme or form testifies to the relationship. However, the evidence is insufficient to reveal the unification of the different sections or movements since these are under restraint of external music proofs. In order to figure out the relationship, thus, identical musical substance should be discovered. In the study the substantial evidence, which can be called unity or unification, is mainly discussed. The unity is illustrated with Brahms's Horn Trio, Op.40 that is one of the Brahms's significant works. The unity found in the Horn Trio is based on the internal structure and structural voice-leading notes. The unity in the Horn Trio is the fundamental structural unity that is divided into initial ascent and voice exchange, and fundamental voice-leading motive. The fundamental unity seriously affects the master piece and penetrates the movements as a whole. Further, it reveals the hidden connections to the historical background of the Horn Trio and the philosophy of Brahms for the music. Even though a piece consists of several sections or movements, the entire piece presents homogeneity. The identity of the composer's underlying philosophical thought suffices to discern the musical unity in a piece. Thus, the investigation of unity is one of the critical ways to understand not merely a piece but also the philosophy of a composer. The study will help to enhance the audience's interpretation of music.

Funding and Effectiveness of Staff Development Programs in Three North Texas School Districts

Description: This dissertation study focused on three aspects of staff development in North Texas: 1) funding sources, 2) types of professional learning programs, and 3) teachers' views of the effectiveness of the funded programs. Qualitative data came from interviews with nine district administrators concerning funding sources and how those resources enhanced teacher skills. Quantitative data came from 1,277 responses from teachers regarding their background and perceptions about staff development. Data from interviews with district administrators were diagrammed to depict elements of funding staff development and to reveal how resources were used to plan, implement, and evaluate staff learning. An analysis of interview data revealed that availability of grants, property tax rates, and student enrollment affected how districts funded staff development. Administrators reported that districts funded professional learning that was planned according to academic initiatives, met the needs of adult learners, and adapted to the changing needs of school communities. Both administrators and practitioners reported that time was a lacking resource critical to developing staff knowledge. Practitioners reported that sufficient opportunity to collaborate with colleagues about learning initiatives was more valuable than teaching materials. Teacher questionnaires were analyzed for possible relationships between participant variables and responses concerning knowledge about funding constraints and professional development experiences. Data revealed that practitioner experience and graduate degrees were not related to teachers' use of knowledge about financial constraints to more efficiently implement learning from staff development. Participants did not perceive professional learning differently than peers. Most teachers connected professional learning with improved teaching practices but a small percent attributed student achievement to their professional learning. The majority of teachers considered collaborative learning settings to elicit more personal professional growth than other formats. The findings of the teacher questionnaire suggest that teaching practices could be impacted if participants gained more knowledge about district financial constraints when developing ...

Funds Budgeted for Educational Programs in Texas Schools during a Period of Changing Enrollment

Description: This study analyzes budgets of Texas school districts experiencing declining enrollments, as opposed to districts with increasing or steady enrollments. This study identifies how schools are expending funds to meet those needs while dealing with enrollment changes. A total of 924 school districts are studied. The changes in average daily attendance from 1993-1994 to 2003-2004 are used to categorize each district as having increasing, stable, or decreasing enrollments. The total dollar amount expended is compared to the total number of students in each district to determine the amount expended per student. The amounts expended for special education career and technology education, bilingual education, and compensatory education are compared to the number of students being served by those programs to determine a dollar amount that can also be compared from the 1993-1994 and 2003-2004 school years. The per-student expenditures for each educational program are compared to the overall per-student expenditures in each enrollment category (increasing, stable, decreasing). The study reveals no clear pattern of change in the comparison of overall spending to individual program spending as district enrollments fluctuated.

Funds of Knowledge and Early Literacy: A Case Study

Description: When teachers are charged with educating students that are racially, culturally, or economically different from them, they may have little information on the culture and type of family involvement of their students. This lack of information contributes to perceptions of working-class families as socially disorganized and intellectually deficient. However, research embodying the theoretical framework funds of knowledge (FoK) attempts to counter deficient models through its assertion that all families possess extensive bodies of knowledge that have developed through social, historical, political, and economic contexts. The primary purpose of this study was to carefully examine Hispanic parents’ support of young children’s early literacy development in the home. The knowledge gleaned from an initial study of home support, by spending time in the home of a Hispanic family provided an avenue for action research in the classroom. A second purpose was to determine if the introduction of FoK ways of learning, when applied in the classroom, had an effect on early literacy skills. In addition, I maintained a journal that chronicled my experiences and led to an autoethnographic study of myself as a transforming white, female, prekindergarten teacher. The results indicated that the family possessed extensive FoK developed through historical, cultural, educational, and social experiences. Results further indicate that introduction of these familial FoK improved the oral language skills of prekindergarten students thus enhancing their early literacy development. Autoethnographic results indicate a personal progression toward not only understanding, but becoming an advocate, for the Hispanic population.

Funds of Knowledge in a Hispanic Household: a Case Study of Family Experiences, Values, and Connections to Education

Description: Traditionally, the field of education has often adopted a negative perspective in their views of minority families’ contributions to the educational progress of their children. However, research embodying the theoretical framework of ‘funds of knowledge’ attempts to counter that model through its assertion that all families possess extensive bodies of knowledge that have developed through social, historical, and cultural contexts. Teachers carry out studies of familial funds of knowledge in order to understand how family experiences shape the knowledge that a child brings to the classroom. There is then, the potential to use that body of knowledge to create meaningful learning experiences that connect prior understanding and experiences to classroom practice. This research served as a case study of the funds of knowledge existing in the home of a Hispanic family and the connections that existed between that knowledge and literacy. The results indicated that the family possessed extensive funds of knowledge that developed through their historical, cultural, and social experiences. They often used family networks, as well as formal and informal literacy experiences to share this knowledge with their children. A key component of the literacy value system that they communicated resulted from a desire to maintain aspects of their culture and heritage through maintaining and improving their children’s reading and linguistic abilities in Spanish. Furthermore, along with their emphasis on Spanish literacy, they held aspirations for their children related to familial and educational values that often stemmed from their expressed desire for their children to lead lives with greater opportunities and positive examples than they had experienced.
