Preparation of PZT nanodots on Nano-Templated Substrates

McMillen M.J.A., Lookman A., Douglas C, Evans P, Bowman R.M., Gregg J.M., Pollard R.J., Queen's University, Belfast & Nanotec NI, UK

There is considerable interest in creation of nanoscale capacitor arrays. For example, in FeRAM technology, which has great potential, significant capacitor cell size reduction and transition to 3D structures, can be achieved within existing CMOS [...]

Anodisation of Thin Film Aluminium

Douglas C, Evans P, Pollard R.J., Queen's University, Belfast & Nanotec NI, UK

Anodisation of alumina is a promising route for the preparation of nano-templates where regular arrays of pores can be produced in foils using a two step anodisation process [1] and Figure 1. The integration of [...]

Nano-Crystalline Ta2O5 Films Deposited by DC Pulsed Magnetron Sputtering

Ligatchev V., Rusli E., Keng L-B, Khuen L-F, Rumin Y., Zhao J., Nanyang Technological University, SG

Thin Ta2O5 layers (95 - 110 nm), deposited at room temperature using pulsed DC magnetron sputtering (PDCMS) in an argon-oxygen (Ar-O2) gas mixture, are investigated. The Ta2O5 samples were prepared at different Ar/O2 flow ratios [...]

Wurtzitic Boron Nitride on Diamond: The Ultimate Epitaxial Wafer for “Semiconductor on Insulator”

Sung J.C-M, Kinik Company, TW

In last four decades, the miniaturization of semiconductors devices (e.g. integrated circuitry) has been following Moore’s Law with feature (e.g. transistors) density double in about every 18 months. This relentless geometrical progression would require the [...]

Cermet Ceramic Coating on Diamond Dresser for In-Situ Dressing of Chemical Mechanical Planarization

Sung J.C-M, Kan K., Kinik Company, TW

In recent years, copper circuitry has been replacing aluminum wires and tungsten via as the dominant interconnections. The polishing of copper circuitry requires using highly acidic solution (e.g. pH = 4) and with strong oxidizing [...]

Fabrication of Hydrophobic Film using Plant Leaves from Nature

Lee H.S., Lee S.M., Lee H.S., Lee S.M., Kwon T.H., Pohang University of Science and Technology, KR

In this study, we have attempted to reproduce the hydrophobic characteristics of plant leaves from nature by replicating the micro/nano feature of leaf surface in UV embossed film. The contact angle (CA) of the replicated [...]

Transition Mechanisms and Phases of Hexane Physisorbed on Graphite

Pint C.L., Roth M.W., Wexler C., University of Northern Iowa, US

We study the transition mechanisms in submonolayer, monolayer, and supermonolayer hexane adsorbed onto graphite, and find that the driving mechanism for the nematic (liquid crystal) phase observed is out-of-plane tilting caused by molecular in-plane rolling, [...]

A Novel Process for Flexible Nano Electronic Web Production

Picard G., Schneider J., Seye M-F, Nanometrix Inc., CA

Nanometrix presents a new concept to make monolayers and ultra-thin films for nano electronic web processing. The novel method was designed ex novo to match with today's industrial production line standards. In this process, the [...]

Surface Roughness as a Function of the DLC Thickness Coating

Salvadori M.C., Martins D.R., Cattani M., University of Sao Paulo, BR

In this work we have analyzed the evolution of surfaces roughness coated with DLC. This study explores substrates with initial roughness (rms) between hundreds of nanometers and just few nanometers. We have used three substrates, [...]

Field Emission of Nanostructured AlQ3 Amorphous Film and the Heat Treatment Effect

Cho C-P, Perng T.P., National Tsing Hua University, TW

There has been a particular interest in tris-(8-hydroxyquinoline) aluminum (AlQ3)-based devices for the development of large-area displays due to the unique properties such as excellent flexibility, high photoconductivity, and nonlinear optical behavior. It is then [...]
