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 [...]

Comparative Analysis of Threshold Voltage Variations in Presence of Random Channel Dopants and a Single Random Interface Trap for 45 nm N-MOSFET as Predicted by Ensemble Monte Carlo Simulation and Existing Analytical Model Expressions

Ashraf N., Vasileska D., Arizona State University, US

Comparative analysis of analytical model and full Ensemble Monte Carlo simulation which takes into account both the short-range and the long-range coulomb interaction in the presence of random dopants and random traps is performed.

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 [...]

Critical exponents from parallel plate geometries with periodic and antiperiodic boundary conditions

Silva Jr. J.B., Leite M.M., UFPE, BR

We present a one-particle irreducible formalism to compute critical exponents for a parallel plate geometries for periodic and antiperiodic boundary conditions, at least at two loop order in perturbation theory.

Self-assembly of Nanostructured ZnO-based Homojunction by Two-step Method

Changand Y.Q., Lu Y.D., Guo J.L., Cui X.D., Yang L., Wang Y.W., Long Y., University of Science and Technology of Beijing, CN

In this work, self-assembly of radial nanostructured ZnO homojunction were synthesized by a kind of two-step method. A supplementary growth mechanism is used to explain the formation of nanostructured ZnO homojunction. Photoluminescence (PL) spectra reveals [...]

Fluoropolymer Nanofibers (VDF-TFE 5 mol%) by Electrospinning

Khalfin R., Cohen Y., Technion – Israel Institute of Technology, IL

Poly(vinylidene fluoride) with 5 mol % of tetrafluoroethylene copolymer (VDF-TFE), is known to have the same crystal structure as pure PVDF as well as similar unique electrical properties. The β-phase of this polymers has strong [...]

Integrated phase-Change memory in Bi2Te3 nanowires

Han N.A., Kim S.I., Yang J.D., Lee K., Sohn H., So H-M, Sohn H., Ahn C.W., Yoo K.H., Yonsei University, KR

Bismuth telluride (Bi2Te3) and its alloys are considered to be the best avaiable materials for near room-temperature thermoelectric applications. Moreover, because low-dimensional thermoelectric materials are expected to have a higher figure of merit due to [...]

Fabrication of Structurally Tailored Cobalt Nanowires

Debburman P.K., Kaur D., Pandya D.K., IIT Delhi, IN

we report an interesting observation of effecting structural transition of electrochemically deposited cobalt nanowires with change in aspect ratio of the nanowires. This change can be controlled by the deposition temperature. These nanowires were deposited [...]

Fabrication of the α–Fe2O3 nanowires and application of the photodetector/optical switching

Hsu L.C., Li Y.Y., National Chung Cheng University, TW

In this study, we demonstrate a rapid and easy method to synthesis α-Fe2O3 nanowires (NWs). The density of the α-Fe2O3 NWs were successfully control by different thickness of Fe thin film within 10 hours by [...]
