Investigation of induced charge damage on self-aligned metal-gate MOS devices

MOS capacitors and NMOS transistors were fabricated with various gate oxides and inter- level dielectrics (ILDs) in order to study the effects of plasma induced charging during the post-metal plasma deposition of an insulating oxide layer. The gate oxides investigated include thermal SiO 2, a low temperature oxide (LTO) deposited by low pressure chemical vapor deposition (LPCVD) using silane and oxygen, and an oxide deposited by plasma enhanced chemical vapor deposition (PECVD) using tetra-ethylortho- silicate (TEOS) as a precursor. A standard-recipe TEOS-based ILD was studied, as well as an alternative recipe that utilized decreased power. Additional wafers were fabricated with an LTO ILD to serve as a control group in order to isolate the influence of the ILD deposition on the respective gate dielectric. By studying C-V and I-V characteristics, both interfacial degradation as well as bulk charging was demonstrated as a result of the PECVD ILD deposition. The investigation demonstrated clear differences in plasma- induced charge effects on the various gate dielectrics. A correlation between the ILD deposition power and the resulting charge influence was established. In addition, post-plasma annealing experiments were done to study the thermal stability of induced charge

A selective annotated bibliography of materials recommended for junior high classrooms regarding resistance during the Holocaust

The Holocaust is a topic that is regularly taught in schools around the country, yet teachers are not necessarily instructed about what to teach regarding this time in history. The purpose of this project was to create a selective annotated bibliography of recommended resources for junior high school teachers to use when teaching about resistance during the Holocaust. The researcher questioned the appropriate role of historical fiction among teaching resources for a junior high school unit about resistance during the Holocaust, and she considered what resources were available for teaching junior high school students about resistance during the Holocaust. The project was completed by selecting resources from the following: the United States Holocaust Memorial Museum’s website, Yad Vashem’s website, Western Illinois University’s Leibovitz Collection Holocaust Curriculum Cases, and Wilson’s Middle and Junior High Core Collection. The selected resources were analyzed using an analysis tool developed by the researcher. An annotated bibliography was then constructed which included a citation, setting, summary, and suggestion for use for each resource

Characterization of Low Temperature Gate Dielectrics for Thin Film Transistors

The goal of this investigation was to ascertain a viable low temperature gate dielectric for an emerging TFT fabrication process at RIT. Various candidates were investigated to find the best solution for a low temperature gate dielectric. Materials studied include low temperature oxide (LTO) using low pressure chemical vapor deposition (LPCVD), plasma enhanced chemical vapor deposition (PECVD) silicon nitride, and PECVD Tetra Ethyl Ortho Silicate (TEOS). Capacitors were fabricated with these materials, as well as a standard thermal oxide as a control. Wafers were examined both with and without anneals at 600°C in order to study bulk oxide and interface charge levels. Surface Charge Analysis (SCA) and C-V curves were generated in order to analyze and compare charge levels of the various treatment combinations

Design Considerations for a New Terminal Area Arrival Scheduler

Design of a terminal area arrival scheduler depends on the interrelationship between throughput, delay and controller intervention. The main contribution of this paper is an analysis of the above interdependence for several stochastic behaviors of expected system performance distributions in the aircraft s time of arrival at the meter fix and runway. Results of this analysis serve to guide the scheduler design choices for key control variables. Two types of variables are analyzed, separation buffers and terminal delay margins. The choice for these decision variables was tested using sensitivity analysis. Analysis suggests that it is best to set the separation buffer at the meter fix to its minimum and adjust the runway buffer to attain the desired system performance. Delay margin was found to have the least effect. These results help characterize the variables most influential in the scheduling operations of terminal area arrivals

Understanding the Importance of Research at Community Colleges and Workforce Centers

In collaboration with Stearns-Benton Employment & Training Council (SBETC) and St Cloud Technical and Community College (SCTCC), a graduate student was assigned to statistically analyze data containing all individuals who passed through both entities within the last five years. The primary objectives of this project were to describe the population passing through both the SBETC and SCTCC and to identify what variables led individuals to succeed in terms of degree and employment obtained. Due to lack of data on type of employment obtained (e.g. position, wage), this report focuses on degree attainment as an indicator of success. In order to make meaningful comparisons regarding degree attainment, a control group was set up using SCTCC students only. The control group was selected using a randomized process and consisted of students who were enrolled at SCTCC in the last five years. Individuals to be placed in the control group were selected based off demographic parameters obtained from the initial dataset. After analyzing the data, it was found that the individuals passing through the SBETC only are significantly older than those who passed through both areas and those who passed through SCTCC only. Following the analysis of age, differences in regards to gender were found. In the dataset containing those who passed through the SBETC only, the percentage of females doubled the percentage of males. In the dataset containing those who passed through both the SBETC and SCTCC, the percentage of females tripled the percentage of males. And lastly, those who passed through the SCTCC had a slightly higher percentage of males. After gender was examined, the percentages of race were identified. In all three samples, it was found that “White” was the majority and ranged from sixty-five percent to seventy-six 5 percent. The second highest percentage in all datasets was “Black or African American”. These percentages ranged from fifteen to twenty percent. All other race variables were less than five percent in each sample. All descriptive statistics including those previously discussed can be found in the appendix section of this report. While comparing both student populations, it was revealed that higher scores on Basic Math and Elementary Algebra sections of the ACCUPLACER predicted that a student will complete their degree. A significant relationship was also identified between the numbers of years taken to complete a degree and the Basic Math section of the ACCUPLACER. As scores on the Basic Math section went up, the numbers of years it took to complete a degree went down. Although this correlation is low, it indicates that basic mathematical skills may play an important role in the time it takes to obtain a degree.Prepared in partnership with Stearns-Benton Employment & Training Council St Cloud Technical and Community College by the Community Assistantship Program (CAP), which is administered by the Center for Urban and Regional Affairs (CURA) at the University of Minnesota

Evaluation of Temporal Spacing Errors Associated with Interval Management Algorithms

This paper seeks to characterize the temporal spacing errors resulting from the use of Interval Management (IM) algorithms. The focus of the current paper is IM concepts and algorithms that realize a specified temporal spacing between a Target aircraft and an Ownship aircraft at the runway threshold. The paper presents an IM algorithm consisting of the following four modules: (i) Target-Landing-Time Estimation Module, (ii) Ownship-Landing-Time Estimation Module, (iii) Ownship Speed Command Computation Module, and (iv) Ownship Thrust Command Computation Module. The overall guidance module is evaluated on a simulation that models aircraft point-mass dynamics, bank-angle auto-pilot dynamics, pitch-axis auto-pilot dynamics, and engine lag dynamics. The simulation environment also consists of actual atmospheric forecasts and realistic spatio-temporally correlated wind uncertainty models. Results obtained from single case simulation as well as Monte-Carlo simulations are presented in the paper. The modeled scenario consisted of an A320 Target equipped with Lateral Navigation/Vertical Navigation (LNAV/VNAV) capabilities followed by an A320 Ownship equipped with the IM algorithm. Both aircraft fly the BIGSUR route to SFO airport using a RAP-13 1-hr wind forecast. 500 Monte-Carlo simulations were conducted with realistic wind uncertainty models. The IM algorithm for this case is seen to have a 90% probability landing time error range of 5.9 seconds, compared to the no-IM solution, which has a 90% probability landing time error range of 33.4 seconds

NASA UAS Traffic Management National Campaign Operations across Six UAS Test Sites

NASA's Unmanned Aircraft Systems Traffic Management research aims to develop policies, procedures, requirements, and other artifacts to inform the implementation of a future system that enables small drones to access the low altitude airspace. In this endeavor, NASA conducted a geographically diverse flight test in conjunction with the FAA's six unmanned aircraft systems Test Sites. A control center at NASA Ames Research Center autonomously managed the airspace for all participants in eight states as they flew operations (both real and simulated). The system allowed for common situational awareness across all stakeholders, kept traffic procedurally separated, offered messages to inform the participants of activity relevant to their operations. Over the 3- hour test, 102 flight operations connected to the central research platform with 17 different vehicle types and 8 distinct software client implementations while seamlessly interacting with simulated traffic
