E. Jan W. ter Maten from the Bergische Universität Wuppertal talks on 27 Jun 2016, 16:15–17:15; Location: S2|17-103 on “Nanoelectronic coupled problem solutions: methods and applications”. Continue reading
Last week all participants of nanoCOPS met at the HU Berlin at the campus Adlershof. nanoCOPS (Nanoelectronic Coupled Problems Solutions) is a collaborative research project within the research program “Information and communication technologies” (ICT) of the Seventh Framework Programme for Research and Technological Development (FP7) funded by the European Union (EU).

The YIC GACM took place last week in Aachen with several highlights: Thorben Casper gave a talk on electrothermal simulation of bondwires as part of our research for the nanoCOPS project and contributed to the science slam on Wednesday. On Friday, Tom Hughes and Alfio Quarteroni gave great presentations on isogeometric analysis and reduced bases, respectively while Mayim Bialik aka Amy Farrah Fowler talked about her scientific and acting career, addressing in particular role models and women in science. Surprisingly, media seems to cover only the last event.
Next week Prof. Dr. Hans Georg Brachtendorf of the Upper Austria University of Applied Sciences (FHO), Hagenberg is visiting the Graduate School CE and TEMF at TU Darmstadt. He will give an overview of the FHO activities in the fp-7 research projects ICESTARS, nanoCOPS, the ENIAC project ARTEMOS, and the Austrian basic research project “Spline/wavelet based methods in circuit simulation” on 12 Jan 2015, 16:15–17:45; Location: S2|17-103.

Dr. Wim Schoenmaker from Magwel NV (Leuven, Belgium) visits TEMF and the Graduate School CE next week. On Monday (1 Dec 2014, 16:15–17:45; Location: S2|17-103) he will talk on Electrostatic discharge (ESD). It is a serious design concern in microelectronic device fabrication and usage. Current spikes of the order of amperes active over a time lap of a nanosecond need to be screened off from the core circuits by ESD protection devices. On-chip silicon controlled rectifiers are used for this purpose. The fast transient effect lead to appreciable induced magnetic fields and a detailed understanding of the temporal response requires that the induced magnetic fields are included. In this talk we will discuss the transient electromagnetic approach to semiconductor device engineering and for completeness also discuss a numerical implementation of the self-induced Lorentz force effects. Although the latter have a small impact on the final results, the computation of these effects is very demanding. In particular, the Newton-Raphson scheme shows peculiar convergence behavior which is not fully understood so far.
All participants of the European project nanoCOPS (Nanoelectronic Coupled Problems Solutions) meet next week in Berlin to discuss their results. TU Darmstadt contributes mainly with analytical models for the estimation of bond wire heating and efficient time-stepping techniques for numerical simulations of coupled electromagnetic/heat problems.
On Friday, November 22, the initial kickoff of the new FP7 EU project nanoCOPS was held in Wuppertal. The computational electromagnetics group at CE/TEMF is involved in research on time domain methods for coupled problems and uncertainty quantification.
Am 1. November ist das EU Projekt nanoCOPS (Nanoelectronic Coupled Problems Solutions) gestartet. Führende Experten aus Industrie und Wissenschaft in Europa wollen gemeinsam neue Methoden entwickeln, die ein verbessertes und erneuertes Design von integrierten Schaltungen ermöglichen. Dafür arbeiten Spezialisten im Schaltungsentwurf, in der Halbleiterentwicklung sowie der Angewandten Mathematik in Forschung und Softwareentwicklung zusammen. Insgesamt sind zwölf Forschungsinstitutionen und Unternehmen an dem Projekt beteiligt, das von der EU im Rahmen des 7. Forschungsrahmenprogramms mit insg. 3,5 Millionen Euro für drei Jahre gefördert wird. Continue reading →
