Abstract
As the technology moving to deep nanometer regime, patterning nano-scale semiconductor features with precision imposes many new challenges for plasma etching. Two of the challenges are evidently critical. One of the challenges is that as the sizes of nano-scale features shrinking down to the sub-10nm regime, plasma etching seems to approach to its ‘limits’ in unprecedented ways. For instance, one may face the question of what is the smallest hole can be actually etched by plasmas. Another challenge is the precision controllability of nano-scale feature pattern transferring as the features sizes, masks materials and thickness being all shrinking down to the molecular cluster dimensions. In this talk, we summarize the recent results of studying plasma etching of true nano-scale features using variety of nano-scale patterns and masks, diblock copolymer (similar to resist) self assembled nano holes and lines and self-assembled organosilicate (similar to silicon oxide) nano patterns, including (1) attempt to categorize the basic types of nano features, (2) discuss the possible true limits for plasma etching, and (3) characterize the main challenges facing by plasma etching in transferring nano-scale features using variety of self-assembled nano features as masks.

Abstract
In this talk, recently developed a block copolymer containing hybrid material and its applications to advanced patterning for semiconductor devices and to generating well-defined nanostructures for photo-voltaic cells will be discussed. We achieved the control over the orientation and alignment of microdomains of the hybrid system in thin films close to that of simple diblock copolymers. By combining with semiconductor processing technology, the hybrid system offers unique ways to fabricate nanostructures without costly, complex, and intensive processing. Examples of tailored nanostructures for specific integration schemes of electronic devices will be addressed along with recent progress in generating nanostructured TiO2 using high-aspect ratio nanotemplates from the hybrid system.

Abstract
In the first part of my talk I will describe our recent work on supercritical fluid based thin film deposition. The objective of our work is to investigate whether solvation forces from supercritical fluids can be used to enable deposition of thin insulating films with good interfacial properties. Mainstream vacuum-based deposition techniques are usually mass transport limited by the low vapor pressure of the precursors, and proceed through a chemical reaction on a heated substrate (>300°C). Our novel chemical approach is a low temperature (<150°C), high pressure process that uses solvation forces from supercritical carbon dioxide to: a) transport high concentrations of soluble organic peroxides and metal organic precursors to a surface, b) provide energy for film formation, and c) accomplish reaction by-product removal. Thin films deposited include: Y2O3, Al2O3, ZrO2 and TiO2 from Al(acac)3, Y(tmhd)3, OTi(tmhd)2, and Zr(acac)4 precursors and tert-butyl peroxide, di-tert-amyl peroxide and a 30% aqueous solution of hydrogen peroxide oxidizers. Thin film deposition rate and composition depends on the precursor, oxidizer and the process temperature (80-140 °C) and pressure (2100 to 3900 psi). Carbonate type impurities desorb after mild anneals. AFM shows smooth surface (rms roughness ~3% of film thickness) that improves upon inert anneals at 400°C. The low process temperature makes the technique attractive for depositions on temperature sensitive substrates.

In the second part of my talk I will compare the nucleation and growth of HfO2 thin films deposited by ALD on both Si-H (HF-last) and SC1 chemical oxide surfaces using TEMAH and TDMAH precursors. The nucleation and interface characteristics of these films have been examined using Rutherford backscattering spectrometry (RBS), spectroscopic ellipsometry (SE), X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM). RBS measurements indicate that the HF-last surface poses an initial nucleation barrier that is quickly overcome during the first few ALD cycles, coinciding with the formation of a Hf-silicate interfacial layer.

Abstract
Electrowetting On Dielectric (EWOD) refers to a parallel-plate device that moves fluid droplets through electrically actuated surface tension effects. These devices have potential applications in biomedical `Lab-On-A-Chip' devices (automated DNA testing, cell separation) and controlled micro-fluidic transport (e.g. mixing and concentration control). The fluid dynamics are modeled using HeleShaw type equations (in 2-D) with a focus on including the relevant boundary phenomena. Specifically, we model contact line pinning as a static (Coulombic) friction effect and effectively becomes an inequality constraint for the motion of the liquid-gas interface that accounts for the "sticking" effect of the interface. The model is presented in a variational framework and is discretized using Finite Elements. The curvature/surface tension is discretized in a semi-implicit way for accuracy using an explicit representation of the interface. Simulations are presented and compared to experimental videos of EWOD driven droplets. These experiments exhibit droplet pinching and merging events and are reasonably captured by our simulations. We also describe an algorithm for controlling particles floating in EWOD driven droplets, which is useful for enabling particle separation and other micro-fluidic tasks. We conclude with simulations demonstrating this ability.

Abstract
This is the eighth in a series of annual symposia on food safety and applied nutrition jointly organized by the Central Science Laboratory (CSL), UK, and the Joint Institute for Food Safety and Applied Nutrition (JIFSAN), University of Maryland, College Park. Each year a different theme is selected. Over the past several years there has been increased interest in the application of nanotechnology to foods and cosmetics. These applications include improved packaging materials, preservatives, flavors and colors. Nanotech materials often have chemical or physical properties that are significantly different from those of their larger counterparts. Due to these differences nanotech materials have the potential for use in a vast variety of products and may pose new and unique safety issues. The focus of the 2007 annual CSL/JIFSAN Joint Symposium on Food Safety and Nutrition will be Nanotechnology in Foods and Cosmetics. Tentatively, symposium sessions will address the identification of regulatory issues, research approaches, characterization and detection methods, routes of exposure and toxicology, and risk analysis and decision making related to food and cosmetic applications of nanotechnology.

Abstract
Dr. Bentley’s research involves bacterial “quorum sensing” to interfere with potential harmful disease-inducing biofilms in the human body. He is collaborating with nanotechnology researchers to create “nanofactories” in the body to deter these harmful effects. Nanofactories are pseudo-cells that are swallowed, inhaled or absorbed through the skin, and travel to a specific location in the body. The tiny biochemical factories could potentially use materials already in the body to manufacture medicine at the first sign of infection or disease. Dr. Shneiderman will feature information visualization tools that enable researchers to accelerate their processes of discovery on basic science problems such a microarray gene expression data analysis and on pharmaceutical drug discovery. These tools played a key role in identifying the 11 genes responsible for muscular dystrophy in a project with Childrens National Medical Center. Another research project involves visualization and search on electronic health records to identify patterns in clinical data, identify common outcomes of varying treatments, and understand the antecedents of medical events such as heart attacks.

Abstract
In today’s optical networks, signal processing is performed with high-speed electrical circuits, which are usually limited to speeds below 40 Gb/s. At higher speeds, the electrical components become prohibitively costly and complicated. One solution to this problem is to perform the signal processing in the optical domain, using ultrafast nonlinear optical effects. While many nonlinear effects have been exploited for optical signal processing, most have the disadvantage that they depend on the incoming polarization state, which cannot be easily controlled or predicted in fiber-optic networks. This polarization dependence is a major obstacle that stands in the way of replacing electronic signal processing with optical processing. In this talk, I will discuss ongoing research to develop polarization insensitive nonlinear optical processing techniques for use in high-speed networks. I will address two key components of a high-speed optical receiver: optical clock recovery and optical switching. We have devised a new polarization-independent 80 Gb/s optical clock recovery system that uses two-photon absorption in an inexpensive silicon photodiode. I will also describe a new method for polarization independent optical switching at speeds up to 160 Gb/s using cross-phase modulation in highly nonlinear optical fibers. Together, these components could form the basis for a new, high-speed polarization independent optical receiver.

Abstract
With the solid consensus which has emerged regarding the causes of global warming, much attention is being turned to finding possible solutions to our energy related problems. In particular, the topic of materials engineering spans many important technologies. Many materials are synthesized under near-equilibrium conditions and therefore adopt structures that are expected based on thermodynamic considerations. As a result, the available material properties are familiar, limited and fixed to some degree. Nanoscience focuses on the new structures that can be obtained by restricting the ways that a relatively small number of atoms may be arranged and combined to form higher order structures, objects, and materials. The availability of new meta-stable structural configurations effectively expands the chemical diversity available in the periodic table of the elements, and affords the discovery and design of new materials with new useful topologies and properties. This talk will illustrate the large and varied role for nanoscience in addressing today’s daunting energy challenges. In particular, we will focus on the nanostructural design principles for hydrogen storage materials, and consider the application of carbon single wall nanotubes in solar energy conversion schemes.

Abstract
There has been an explosive development in materials development which uses nanoscale materials to probe biological processes and diagnose medical conditions (such as tumor detection). There are unique aspects of nanoscale materials which allow them to preferentially penetrate and be retained by biological cells and tissue and there have been developments in new ways to detect and image and nanomaterials in cells and biological tissue. Further, the size scale of nanoprobes will allow us to build complexity into nanoprobes which allow them to be multi-functional, with both diagnostic and drug delivery. However, we must also be aware that these nanomaterials can have drastically different behavior in biological tissue than larger scale materials of exactly the same composition, so issues of societal and ethical outcomes must also be considered. The colloquium will be structured to address graduate students, postdoctoral fellows, directors of public granting agencies, and policy makers.

Abstract
The integrated circuit revolution changed our lives by automating computational tasks on a grand scale. My group has been asking whether a similar revolution could be enabled by automating biological tasks. To that end, we have developed a method of fabricating very small plumbing devices – chips with small channels and valves that manipulate fluids containing biological molecules and cells, instead of the more familiar chips with wires and transistors that manipulate electrons. Using this technology, we have fabricated chips that have thousands of valves in an area of one square inch. We are using these chips in applications ranging from screening to structural genomics to ultrasensitive genetic analysis. However, there is also a substantial amount of basic physics to explore with these systems – the properties of fluids change dramatically as the working volume is scaled from milliliters to nanoliters!

Abstract
Material interfaces are the predominant focus for fabricating elaborate, functional nanostructures. Most standard small structure fabrication techniques and recent novel approaches have been applied to various material interfaces producing a range of devices that take advantage of molecular scale phenomena. In this talk we briefly review methods that access this molecular scale and will examine two disparate examples of material interfaces that hold potential for important new applications: the high electron mobility two-dimensional electron heterostructure and hybrid material interfaces composed of semiconductors and peptides. Our findings in these disciplines have opened possibilities of applications that include quantum computing for the high mobility electron system and single protein detection for the hybrid material interfaces. The routes and findings leading to these goals will be presented, with description of the odd similarities in properties exposed in studying the two different interfaces.

Abstract
This talk discusses bottom up assembly of nanoscale components.We begin by addressing nanoassemblyby manipulation with SPMs(Scanning Probe Microscopes), which is a relatively well established process for prototyping nanosystems. Experimental results are presented which show that SPM manipulation can be used with minimal user intervention to accurately and reliably position molecular-sized components. These can then be linked by chemical or physical means to form subassemblies, which in turn can be further manipulated. Applications in building wires, single-electron transistors and nanowaveguidesare presented. Finally, we discuss an emerging paradigm in self-assembly, in which active elements (nanorobots) are used to build nanostructures. These robots have the limited capabilities we expect to find in the nanorobotsof the future, and achieve interesting global behaviors throughlocal interactions. Simulation results show that arbitrary shapes can be constructed by swarms of these robots.

Abstract
Carbon nanotubes (CNs) are attracting increasing interest as building blocks for nano-electronics applications. Due to their unique properties, enabling e.g. ballistic transport at room-temperature over several hundred nanometers, high performance CN field-effect transistors (FETs) have become feasible. The successful improvement of CNFET performance, however, is not merely a result of the application of established concepts. It is indeed a consequence of the detailed study of the material specific properties that have guided the research on CN-based transistor applications. An example of this is the critical observation that CNFETs in fact behave as Schottky barrier devices. It was found that switching in nanometer size semiconductors, such as carbon nanotubes, contacted with source/drain metal electrodes is determined entirely by the metal/semiconductor interfaces and their field-dependence. Analyzing this particular type of nanotube property quantitatively, we have been able to relate the performance of nanotube devices with their diameters. Another important milestone has been the successfully fabrication of the first band-to-band tunneling CNFET with a much more abrupt switching behavior than can be obtained with any conventional transistor approach, evidence that nano-materials can, in principle, be used to create drastically different and more efficient switches.

Abstract
The novel optical properties of sub-wavelength-scale nanostructures can be amplified by arranging the nanostructures in ordered arrays. The array structure superimposes the optical coherence of the array structure on the properties of individual nanoparticles. We use focused ion-beam lithography to create arrays of nanoparticles and nanoholes that have unusual optical properties. As examples, we consider (1) second-harmonic generation from centrosymmetric arrays of centrosymmetric noble-metal nanoparticles, and (2) modulating the extraordinary optical transmission through sub-wavelength hole arrays by means of the metal-insulator transition in vanadium dioxide.

Abstract
Silicon based highly integrated CMOS technology will reach its physical limits during the next 10 to 15 years. Great effort is therefore made worldwide to push CMOS to its limits and to find Beyond-CMOS solutions based on quantum devices and nanostructures which could overcome the physical limits of MOSFETs, in particular concerning power consumption. In this context semiconductor nanoculumn devices with new functionalities compared to MOSFET devices and circuits attract considerable interest in order to complement advanced CMOS circuits in the future. Both lithographic top-down strategies and bottom-up approaches by self-organised growth of semiconductor nanowhiskers are investigated at present in order to realise nanocolumn devices. Examples for both techniques are presented. For lithographically prepared GaAs/AlAs-nanocolumn resonant tunneling devices (RTD) the behaviour of the strongly non-linear I-V-characteristics with negative differential resistance (NDR) is studied down to column diameters of 50 nm. For the smallest 50 nm devices a new quantum collimation effect was detected which improves the RTD performance considerably and which might be of general interest for all kinds of nanocolumn device concepts. As an example for the bottom-up approach self organized growth of GaN-nanowires is considered. In these nanowires a diameter dependent photoconductivity is observed, which is quantitatively explained by the interplay between the column diameter and the extension of surface depletion zones. In conclusion, some device examples (RTD, SET) in the material system InAs/InP are presented and ideas about wiring of nanocolumns into circuits.

Abstract
The development of simple and rapid techniques for the site-specific immobilization of single molecules or molecular aggregates is critical in many areas of nanoscience, e.g. for the definition of molecular contacts in ‘molecular electronics’ or the miniaturization of high throughput assays in molecular biology. Different techniques and strategies based on Scanning Probe Microscopies have been developed to chemically pattern substrates on a molecular length scale; they are, however, limited in speed and are difficult to combine with conventional microfabrication techniques. Here we present alternative paths to create molecular nanopatterns by combining electron beam lithography with novel self-assembling materials (SAMs). Since SAMs show specific sensitivity to irradiation, aliphatic and aromatic SAMs have been used as positive and negative electron beam resists, templates for growing polymer brushes with a resolution of 20 nm, for the manufacturing of biomolecular nanopatterns, and as spacers for the preparation of stable and defect free metal/organic monolayer/ metal sandwich structures.

Abstract
Nano-optical devices are raising more and more interest for a variety of applications. From single molecule detection at high molecular concentration by Fluorescence Correlation Spectroscopy (FCS) through optical multiplexing with photonic crystal structures into the exciting field of negative index of refraction materials, the hardware functional dimensions and surely the tolerances are reaching the lower tens of nanometer range. The fabrication of such devices, i.e. the machining of optically interesting materials and material combinations (dielectric, semiconducting, or metallic) at this scale needs adaptation of classical nanostructuring technologies like Electron Beam Lithography (EBL), or the application of novel machining technologies like Focused Electron Beam induced deposition (FEBID). (FEBID) is a versatile 3-D construction technology of sub-100 nm structures. It is a very complex process, not yet fully understood. Examples of functional devices produced either by EBL or FEBID will be presented, as well as results of measurements on the e-beam induces processes.

Abstract
Recent dramatic progress of nanotechnology and biological science allows us to combine soft materials (e.g. biomolecules, self-assembled monolayer etc.) with solid nanostructures (e.g. nanoparticles, carbon nanotubes, electronic circuits etc.) to build a generation of new hybrid nanoscale devices such as molecular electronic circuits, nanoscale biological sensors , and protein motor-based nanomechanical systems . However, a major stumbling block holding back their industrial applications is a difficulty in high throughput assembly for device fabrication. One promising nano-manufacturing method for these hybrid devices is the surface- programme d assembly process. In this strategy, direct deposition methods such as dip-pen nanolithography [1] are utilized to functionalize the desired solid substrate area with organic molecules, and nanostructures (e.g. nanoparticles [2] , carbon nanotubes [3] , proteins etc.) in the solution are specifically assembled onto the functionalized area via self-assembly mechanism . In this presentation, I will discuss: 1) nano-manufacturing methods for hybrid nanoscale devices and 2) new scientific issues related with hybrid nanostructures. Future prospects and possible applications of hybrid devices also will be discussed.
