A new route to control the enhancement of structural and anisotropy ordering in two-dimensional particle arrays

Regtmeier A., Wittbracht F., Dück I., Rempel T., Weddemann A., Hütten A., Bielefeld University, DE

For the realization of data storage devices two fundamental requirements are necessary to guarantee good functionality: a) particles need to be arranged within a sizeable, two-dimensional monolayer of high spatial ordering and b) magnetic states [...]

The SEM/FIB Workbench: Automated Nanorobotics System Inside of Scanning Electron or Focussed Ion Beam Microscopes

Klocke V., Burkart I., Kaufmann R., Klocke Nanotechnik GmbH, DE

With light microscopes it is natural for everybody to use manual or automatic toolsets like tweezers, knives, hooks, probes and several different measurement tools. The operators of SEM, FIB or Dual Beam systems generally work [...]

Correlation of Microstructure and Tribological Properties of Dry Sliding Nanocrystalline Diamond Coatings

Wiora M., Sadrifar N., Brühne K., Gluche P., Fecht H-J., Ulm University, DE

Nanocrystalline diamond (NCD) offers great potential for many micro-mechanical systems, particularly where low friction, reliability and mechanical integrity are of great importance. The reduction of grain size in NCD films to several nanometers is, however, [...]

Automated test system for in-situ testing of reliability and aging behaviour of thermal interface materials

Abo Ras M., Berliner Nanotest and Design GmbH, DE

The on-going need for miniaturization and speed in electronics industry has brought a requirement for better performing thermal management systems. Therefore we have developed a test stand to characterize the aging behaviour of most common [...]

Fracture mechanical test methods for interface crack evaluation of electronic packages

Keller J., Maus I., Pape H., Wunderle B., Michel B., AMIC Angewandte Micro-Messtechnik GmbH, DE

The ongoing development of highly integrated electronic packages leads to a steadily increasing number of material interfaces within a package. In combination with increasing harshness (vibration, humidity, temperature) of the system environment the reliability of [...]

Reliability Analysis of Low Temperature Low Pressure Ag-Sinter Die Attach

Mrossko R., Oppermann H., Wunderle B., Winkler T., Michel B., Berliner Nanotest und Design GmbH, DE

The amount of heat which has to be dissipated from power electronics and microprocessors increases more and more due the ongoing miniaturization. Therefore new interface materials with high electrical and thermal conductivity have to be [...]

Three-dimensional Deformation Analysis of MEMS/NEMS by means of X-ray Computer-Tomography

Hammacher J., Dost M., Faust W., Scheiter L., Erb R., Michel B., Fraunhofer ENAS, DE

High resolution x-ray computertomography allows the non-destructive 3D-analysis of materials and compounds. Therefore, information of the internal structure of the material or the device becomes available, which are otherwise only gained by destructive analysis. But [...]

Poly(butyl terephthalate)/oxytetramethylene + oxidized carbon nanotubes hybrids: mechanical and tribological behavior

Brostow W., Broza G., Datashvili T., Kopyniecka A., TUHH, DE

Carbon nanotubes (CNTs) have been used for providing mechanical reinforcement to polymers [1, 2] – as have been other approaches. Much less attention than to mechanics has been paid to improvement of tribological properties of [...]

A novel strategy for fabrication of mesoporous crystalline tin dioxide films with large pores and fully crystalline walls

Fattakhova-Rohlfing D., Rathousky J., University of Munich (LMU), DE

We have developed a new facile procedure for manufacturing crystalline thin films of tin oxide with a uniform mesoporous architecture and full crystallinity of the walls. The procedure is based on the evaporation-induced self-assembly of [...]

Biocompatible Nanomembranes based on PEGylation of Cross-Linked Self-Assembled Monolayers

Meyerbroeker N., Eck W., Zharnikov M., University of Heidelberg, DE

We present a novel ultrathin and biocompatible membrane based on highly cross-linked and subsequently PEGylated self- assembled monolayers. These layers can be removed from their substrates and freely suspended over TEM grids. Possible applications of [...]
