Integration of High-K Dielectrics and Metal Gates into Submicron NMOS Transistors at RIT

Zirconium oxide, a high-k gate dielectric, and molybdenum, a refractory metal, were successfully integrated into an existing submicron NMOS transistor process at RIT. Submicron high-k gate dielectric metal gate transistors were produced as a result of this project, and electrical characteristics were compared to reference submicron transistors fabricated with 75 A silicon dioxide gate dielectrics and polysilicon gates

Investigation of Sputtered Hafnium Oxides for Gate Dielectric Applications in Integrated Circuits

This work investigated high permittivity hafnium based dielectric films for use in future generation metal oxide semiconductor field-effect transistor (MOSFET) technologies. For the sub- 100 nm MOS structure, the conventional Si02 gate dielectric required is becoming too thin ( Two deposition processes were used for investigating hafnium oxide: A traditional reactive sputtering process using a hafnium target and oxygen along with a metal oxidation process in which hafnium metal was deposited and subsequently oxidized in a rapid thermal processor. The films and their interfacial layers were studied using transmission electron microscopy and Rutherford backscattering. Suppression of the interfacial layers was attempted by utilizing various pre-deposition cleaning processes, nitrogen incorporation, and multiple annealing conditions. Statistical analysis was performed on many film properties including: thickness and refractive index by ellipsometry, equivalent oxide thickness (EOT), relative permittivity (sr), total charge density (Nss) via capacitance-voltage analysis (C-V), oxide charge density (Qox) and interface trap charge density (DiT) from surface charge analysis, and breakdown strength vi and leakage current density from current-voltage analysis (I-V). Hafnium oxide was successfully integrated into an RIT sub-micron NMOS process, and operational 0.5 um transistors were fabricated and tested

Condensation of Hard Spheres Under Gravity

Starting from Enskog equation of hard spheres of mass m and diameter D under the gravity g, we first derive the exact equation of motion for the equilibrium density profile at a temperature T and examine its solutions via the gradient expansion. The solutions exist only when \beta\mu \le \mu_o \approx 21.756 in 2 dimensions and \mu_o\approx 15.299 in 3 dimensions, where \mu is the dimensionless initial layer thickness and \beta=mgD/T. When this inequality breaks down, a fraction of particles condense from the bottom up to the Fermi surface.Comment: 9 pages, one figur

Global climate policy and local energy politics: is India hiding behind the poor?

Along with the large middle-income countries Brazil, China, and South Africa, India has been put under increasing pressure to shoulder parts of the mitigation burden and commit to national emission reduction targets. India, however, refers to its limited capacity and widespread poverty. Is India hiding behind its poor? While others examine the distribution of emissions within the country to answer this question, we study domestic policy making for energy subsidies and access to clean energy. Empirical evidence suggests that domestic policy making is at least partially consistent with the pro-poor arguments advanced at the international level. Given their large number and the country's democratic system, the poor do have some weight in Indian politics. However, pro-poor policies end where they do not translate into greater vote shares. Moreover, India's international position ignores the existing complementarities between climate-friendly and pro-poor activities

Optimal Dynamical Decoherence Control of a Qubit

A theory of dynamical control by modulation for optimal decoherence reduction is developed. It is based on the non-Markovian Euler-Lagrange equation for the energy-constrained field that minimizes the average dephasing rate of a qubit for any given dephasing spectrum.Comment: 6 pages, including 2 figures and an appendi

(In)visible Ghosts in the Machine and the Powers that Bind: The Relational Securitization of Anonymous

This paper analyzes the formation and subsequent securitization of the digital protest movement Anonymous, highlighting the emergence of social antagonists from communication itself. In contrast to existing approaches that implicitly or explicitly conceptualize Othering (and securitization) as unidirectional process between (active) sender and (passive) receiver, an approach that is based on communication gives the "threat” a voice of its own. The concept proposed in this paper focuses on "designations” as communicating rules and attributes with regard to a government object. It delineates how designations give rise to the visibility of political entities and agency in the first place. Applying this framework, we can better understand the movement's path from a bunch of anonymous individuals to the collectivity "Anonymous,” posing a threat to certain bases of the state's ontological existence, its prerogative to secrecy, and challenging its claim to unrestrained surveillance. At the same time, the state's bases are implicated and reproduced in the way this conflict is constructed. The conflict not only (re)produces and makes visible "the state” as a social entity, but also changes or at least challenges the self-same entity's agency and legitimacy. Such a relational approach allows insights into conflict formation as dynamic social proces
