Nanopantography: A Method for Parallel Writing of Etched and Deposited Nanopatterns

(Georgia Institute of Technology, 2009-10-19) Donnelly, Vincent M.

Nanopantography is a radically different approach for parallel writing of pre-selected nanopatterns over large areas. Arrays of micro-electrostatic lenses (e.g., small round holes through a metal/insulator structure) on a substrate such as a silicon wafer focus ion beamlets at the bottoms of the holes. When the wafer is tilted, the focal points in each hole are laterally displaced, allowing the focused beamlets to be rastered across the hole bottoms and write patterns in a massively parallel manner. Examples will be given of Si nanoetching and Ni nanodot deposition.
Nanotechnology and Its Impact on Construction

(Georgia Institute of Technology, 2009-01-27) Teizer, Jochen

This presentation will review nanotechnology programs and summarize the existing knowledge and understanding of nanotechnology, explore existing nanotechnology ideas, needs, and products in various industry fields, learn from their history and experiences during product implementation, and quantify their potential value and implementation for construction. Benefits and limitations of selected nanotechnology applications will be evaluated for high impact potential in construction.
Silicon-Based Resonant Microsensors

(Georgia Institute of Technology, 2008-10-21) Brand, Oliver

The presentation gives an introduction to resonant microsensors providing a frequency output signal. These sensors generally benefit from an excellent frequency resolution, which is ideally limited only by the length of the counting period and the short-term frequency stability of the microstructure's resonance frequency. Device-level and system-level approaches to generate a measurand-dependent frequency signal are discussed and concepts to improve Q-factor, short-term frequency stability and ultimately sensor resolution are highlighted. Furthermore, the presentation discusses frequency drift challenges and introduces methods for drift compensation. The above concepts and approaches are illustrated using two resonant microsensor examples: (i) a mass-sensitive microsensor platform for gas- and liquid-phase chemical sensing based on disktype silicon microstructures and (ii) a cantilever-based resonant magnetic microsensor with a resolution suitable for Earth field applications.
State-Level Nanotechnology Policy Initiatives and Implications for Georgia

(Georgia Institute of Technology, 2008-09-23) McKeon, Patrick Edward Timothy

Nanotechnology has been proposed to hold the next industrial revolution. This interest has been incorporated into increases in research activities, commercialization efforts, and further economic development. The National Nanotechnology Initiative has provided a foundation and scope for these activities from a policy perspective. In addition to national efforts there have been local, state, and regional initiatives to bolster and supplement the national policies. This study looks into the factors driving the policies, the policy actions at the state-level, and the results of these policies. The work analyzes eighteen states and their policies were characterized into a system of developed formal models. There was additional focus given to the nano-specific assets in Georgia, and the potential plans to be implemented at the state-level to enhance its nanotechnology prominence as the new state-funded Nanotechnology Research Center comes on-line. This work was supported by the Program in Science, Technology, and Innovation Policy through the School of Public Policy and the Enterprise Innovation Institute at the Georgia Institute of Technology.
High-Performance Chip-to-Chip Communications Using Advanced Materials and Structures

(Georgia Institute of Technology, 2008-09-09) Kohl, Paul A. ; Spencer, Todd ; Osborn, Tyler

The "off-chip" bandwidth is a major bottleneck causing system delays and limited throughput, especially in areas such as processor-to-memory bandwidth and processor-to-network. The ITRS cites off-chip signal bandwidth exceeding 60 GHz within 10 years. Organic substrates (i.e. chip packages or interposers) with flip-chip solder connections are the core of the first and second level of interconnect. Off-chip bandwidth is limited to several GHz due to frequency dependent attenuation, signal reflections, and crosstalk within the polymer dielectric, via structures, and I/O signal path transitions within the chip substrate and mother board. In this work, we have introduced advances in off-chip interconnect using air-isolated, coaxial links on substrates and boards to demonstrate ultra high-speed chip-to-chip and chip-to-network communications. New approaches have been found to fabricating high frequency I/O, air-and isolated coaxial links on the substrate. The materials, processes and electrical characteristics will be presented.
Development of Implantable Wireless Pressure Sensors for Chronic Disease Management

(Georgia Institute of Technology, 2008-05-13) Fonseca, Michael Agapito

CardioMEMS is a medical device company that has developed and is commercializing a proprietary wireless sensing and communication technology for the human body. Our technology platform is designed to improve the management of severe chronic cardiovascular diseases such as heart failure and aneurysms. Our miniature wireless sensors can be implanted using minimally invasive techniques and transmit cardiac output, blood pressure and heart rate data that are critical to the management of patients. Due to their small size, durability, and lack of wires and batteries, our sensors are designed to be permanently implanted into the cardiovascular system. Using radiofrequency (RF) energy, our sensors can transmit real-time data to an external electronics module, which then communicates this information to the patient’s physician.
A Realistic View of Commercializing Nanotechnology Within the Chemical and Various Other Industries

(Georgia Institute of Technology, 2008-02-26) Kirk, Richard A. ; Blevins, Daniel

Nanotechnology has become "The Word" across all business lines; yet, few understand this new technology and the future impact on their prospective businesses. This talk will provide a framework for understanding nanotechnology and how markets should be evaluated for supply. Also provided is identification of the likely commercial applications for nanotechnology and generalization on confronted obstacles and areas where needs are growing. Nanotechnology commercialization will require a shift in mindset, and methods currently being implemented by R&D and Sales and Marketing will be unable to properly introduce this new technology to various potential customers. We have found that tremendous opportunities exist for a different classification of personnel for Sales and Marketing in Nanotechnology. Since there will exist no standardization of processes, personnel will be taking a voyage of discovery, product by product and case by case. Outline of HS and College courses that future “Nanotechnologist” should consider in preparation for involvement with this new technology. This program will provide a glimpse of the future in commercialization and challenges for Nanotechnology products.
Introduction to Focused Ion Beam Technology and its Application

(Georgia Institute of Technology, 2008-01-22) Kranz, Christine

Within the last decade Focused Ion Beam technology has developed from a routine semiconductor tool into a versatile research instrument for characterization and prototyping. A major step towards the convergence of nanotechnology and nanoscience is the development and utilization of technologies, which allow precise patterning and assembly of features at a nanoscale. Dual beam FIB/SEM technology provides unsurpassed control and resolution during milling, deposition, and characterization at the nanoscale, thereby enabling high-resolution 3-D prototyping, machining, and structuring crucial to the development of next-generation functional nanodevices. An unambiguous advantage of FIB technology is the possibility for maskless milling and deposition processes. Application of FIB technology includes failure analysis, circuit repair and mask repair in microelectronics and TEM sample preparation. Recently, FIB has been also used in fabrication of scanning probe tips, optical devices and sensor technology. Nanostructuring using focused ion beams is governed by different parameters given by the beam profile, by the angle of incidence, by ion species, ion dose, and energy, and by the structural and chemical change of the sample by ion implantation. Within this presentation an overview of this technology along with novel applications but also limitations will be presented.
