In-situ Quantitative Integrated Tribo-SPM Nano-Micro-Metrology

Gitis N., Daugela A., Vinogradov M., CETR, US

Quantitative nano-metrology tools have become a standard in semiconductor, data storage and other hi-tech industries where products are tested for thin-film properties. Though it is critical to characterize advanced thin films and coatings, today’s off-line [...]

Durable Anti-Stiction Coatings by Molecular Vapor Deposition (MVD)

Kobrin B., Chinn J., Ashurst R.W., Applied Microstructures, Inc., US

Development of new SAM coatings using a “sequential” vapor technique which can be deposited on almost any substrate material and withstand harsh environments is reported. Technical benefits for the improved surface modification method called Molecular [...]

Microwave Irradiation an Alternative Source for Conventional Annealing: A Study of Aluminum Oxide Thin Films by Sol-Gel Process

Phani A.R., Santucci S., University of L'Aquila, IT

Thin films of Al2O3 have been prepared by simple sol-gel process on to quartz substrates, and the as deposited films are subjected to annealing different temperatures and microwave irradiation at different powers. It is evident [...]

Molecular Fan: A Heat Sink for Nanoelectronic Devices

Sizemore C.A., Recchia M.L., Kim T., Lin C-T, Northern Illinois University, US

Currently, electrical components are cooled by conduction of heat to a heat sink, which is cooled by convection in air. The warm air is then removed from the system using a mechanical fan. As technology [...]

Silicon Surface Modification with Silane-functionalized Polymers

Viswanathan K., Long T.E., Ward T.C., Virginia Tech, US

The synthesis of trimethoxysilane end-capped linear polystyrene (PS), star-branched PS, and subsequent silicon (Si) surface modification with the linear and star polymers are described. Trimethoxysilane terminated PS was synthesized using sec-butyl lithium initiated anionic polymerization [...]

Development of a New Treatment to Induce Anatase Growth on Ti

Pedeferri M., Bottani C.E., Cattaneo D., Li Bassi A., Del Curto B., Brunella M.F., Politecnico di Milano, IT

Aim of the work has been the evaluation of the application of a novel treatment of the Ti surface in order to increase anatase growth. Two different anodizing methodologies, previously developed were considered, followed by [...]

Low Temperature Deposition of High-Quality Nanometer-Thick Dielectric Films in an Electron Cyclotron Resonance (ECR) Plasma-Enhanced CVD System

Xie L., Deng J., Shepard S., Tsakirgis J., Chen E., Harvard University, US

One of the challenges facing in nanofabrication is to deposit dielectric films with thickness compared to the feature size under fabrication, typically in a range of nanometer, for the purposes such as gate dielectrics, surface [...]

Functional Nano-Structured Surfaces for Protein Based Sensors

Valsesia A., Meziani T., Colpo P., Lejeune M., Ceccone G., Rossi F., Joint Research Center, European Commission, IT

The reduction of the typical length scale in the creation of patterned surfaces is of high interest in the field of biosensor and bio-interacting materials. During the last few years several researchers explored the influence [...]

Formation of Biotinylated Alkylthiolate Self-Assembled Monolayers on Gold

Canaria C.A., Maloney J.R., Yu C-J, Smith J.O., Fraser S.E., Lansford R., California Institute of Technology, US

We demonstrate the successful formation of functional biotinylated monolayers on gold surfaces using aqueous solvents. Cyclic voltammetry (CV), alternating current voltammetry (ACV), and fluorescence microscopy have been used to characterize the films. Protein binding assays [...]

Ferroelectric Properties of FIB-prepared Single Crystal BaTiO3 Nanocapacitors

Schilling A., Saad MM., Baxter P., Adams TB., Bowman RM., Gregg JM., Morisson FD., Scott JF., Queen's University, Belfast & Nanotec NI, UK

Measurements on free standing single crystal barium strontium titanate capacitors made using focused ion beam micromachining with thicknesses down to 75 nm, show a dielectric response typical of large single crystals, rather than conventional thin [...]
