Within the power module package wire bonding is used as an interconnection technology. In recent years, aluminum wire has been used preferably, but an ever-growing market of powerful and efficient power modules requires a material with better mechanical and electrical properties. For this reason, a technology change from aluminum to copper is indispensable. However, the copper wire bonding process reacts more sensitive to parameter changes. This makes manufacturing reliable copper bond connections a challenging task. The aim of the BMBF funded project Itsowl-InCuB is the development of self-optimizing techniques to enable the reliable production of copper bond connections under varying conditions. A model of the process is essential to achieve this aim. This model needs to include the dynamic elasto-plastic deformation, the ultrasonic softening effect and the proceeding adhesion between wire and substrate. This paper focusses on the pre-deformation process. In the touchdown phase, the wire is pressed into the V-groove of the tool and a small initial contact area between wire and substrate arise. The local characteristics of the material change abruptly because of the cold forming. Consequently, the pre-deformation has a strong effect on the joining process. In [1], a pre-cleaning effect during the touchdown process of aluminum wires by cracking of oxide layers was presented. These interactions of the process parameters are still largely unknown for copper. In a first step, this paper validates the importance of modeling the pre-deformation by showing its impact on the wire deformation characteristic experimentally. Creating cross-section views of pre-deformed copper wires has shown a low deformation degree compared to aluminum. By using a digital microscope and a scanning confocal microscope an analysis about the contact areas and penetration depths after touchdown has been made. Additionally, it has to be taken into account that the dynamical touchdown force depends on the touchdown speed and the touchdown force set in the bonding machine. In order to measure the overshoot in the force signals, a strain gauge sensor has been used. Subsequently, the affecting factors have been interpreted independently Furthermore, the material properties of copper wire have been investigated with tensile tests and hardness measurements. In a second step, the paper presents finite element models of the touchdown process for source and destination bonds. These models take the measured overshoot in the touchdown forces into account. A multi-linear, isotropic material model has been selected to map the material properties of the copper. A validation of the model with the experimental determined contact areas, normal pressures and penetration depths reveals the high model quality. Thus, the simulation is able to calculate and visualize the three dimensional pre-deformation with an integrated material parameter of the wire if the touchdown parameters of the bonding machine are known. Based on the calculated deformation degrees of wire and substrate, it is probably possible to investigate the effect of the pre-deformation on the pre-cleaning phase in the copper wire bonding."}],"project":[{"name":"Intelligente Herstellung zuverlässiger Kupferbondverbindungen","grant_number":"02 PQ2210","_id":"92"}],"publication":"Proceedings of the 47th International Symposium on Microelectronics (IMAPS)","citation":{"apa":"Unger, A., Sextro, W., Althoff, S., Eichwald, P., Meyer, T., Eacock, F., &#38; Brökelmann, M.

However, the physical modeling of the ultrasonic softening effect is notoriously difficult because of its highly non-linear character and the absence of a proper measurement method. In a first step, this paper validates the importance of modeling the ultrasonic softening by showing its impact on the wire deformation characteristic experimentally. In a second step, the paper presents a data-driven model of the ultrasonic softening effect which is constructed from data using machine learning techniques. A typical caveat of data-driven modeling is the need for training data that cover the considered domain of process parameters in order to achieve accurate generalization of the trained model to new process configurations. In practice, however, the space of process parameters can only be sampled sparsely. In this paper, a novel technique is applied which enables the integration of prior knowledge about the process into the datadriven modeling process. It turns out that this approach results in accurate generalization of the data-driven model to unseen process parameters from sparse data."}],"project":[{"name":"Intelligente Herstellung zuverlässiger Kupferbondverbindungen","grant_number":"02 PQ2210","_id":"92"}],"date_created":"2019-05-20T13:38:10Z","type":"conference","department":[{"_id":"151"}]},{"department":[{"_id":"280"}],"type":"mastersthesis","date_created":"2017-10-17T12:42:08Z","project":[{"name":"SFB 901","_id":"1"},{"_id":"7","name":"SFB 901 - Subprojekt A3"},{"name":"SFB 901 - Project Area A","_id":"2"}],"citation":{"ieee":"N.

There are a number of studies for safe node exclusion if the overlay is in a well-defined state initially. Surprisingly, the problem is not formally studied yet for the case in which the overlay network is in an arbitrary initial state, i.e., when looking for a self-stabilizing solution for excluding leaving nodes. We study this problem in two variants: the Finite Departure Problem (FDP) ) and the Finite Sleep Problem (FSP). In the FDP the leaving nodes have to irrevocably decide when it is safe to leave the network, whereas in the FSP, this leaving decision does not have to be final: the nodes may resume computation if necessary. We show that there is no self-stabilizing distributed algorithm for the FDP, even in a synchronous message passing model. To allow a solution, we introduce an oracle called NIDEC and show that it is sufficient even for the asynchronous message passing model by proposing an algorithm that can solve the FDP using NIDEC. We also show that a solution to the FSP does not require an oracle.","lang":"eng"}],"date_created":"2017-10-17T12:42:08Z","file":[{"creator":"florida","date_created":"2018-03-20T07:00:28Z","file_name":"393-departures.pdf","access_level":"closed","file_size":287539,"relation":"main_file","date_updated":"2018-03-20T07:00:28Z","file_id":"1384","content_type":"application/pdf","success":1}],"department":[{"_id":"79"}],"type":"conference"},{"type":"journal_article","keyword":["tet_topic_waveguide"],"department":[{"_id":"61"}],"file":[{"content_type":"application/pdf","success":1,"file_id":"3938","access_level":"closed","file_size":364221,"file_name":"2014_07_Hoekstra,Hammer_General relation for group delay and the relevance of group delay for refractometric sensing_OSA.pdf","date_updated":"2018-08-20T10:00:33Z","relation":"main_file","date_created":"2018-08-20T10:00:33Z","creator":"hclaudia"}],"date_created":"2018-08-20T09:59:35Z","abstract":[{"text":"The relevance of our definition for sensitivity in refractometric sensing, being the relative change in the transmittance\r\nof a certain output channel of an optical device over the change in the refractive index of the probed\r\nmaterial, is discussed.

To benefit from the growing plethora of available services, sophisticated service discovery approaches are needed that bring service requests and offers together. Such approaches rely on rich service descriptions, which specify also the behavior of provided/requested services, e.g., by pre- and postconditions of operations. As a base for the specification a data schema is used, which specifies the used data types and their relations. However, data schemas are typically heterogeneous wrt. their structure and terminology, since they are created individually in their diverse application contexts. As a consequence the behavioral models that are typed over the heterogeneous data schemas, cannot be compared directly. In this paper, we present an holistic approach to normalize rich service description models to enable behavior-aware service discovery. The approach consists of a matching algorithm that helps to resolve structural and terminological heterogeneity in data schemas by exploiting domain-specific background ontologies. The resulting data schema mappings are represented in terms of Query View Transformation (QVT) relations that even reflect complex n:m correspondences. By executing the transformation, behavioral models are automatically normalized, which is a prerequisite for a behavior-aware operation matching.","lang":"eng"}],"file":[{"content_type":"application/pdf","success":1,"file_id":"1383","date_updated":"2018-03-20T06:59:55Z","relation":"main_file","access_level":"closed","file_size":1107805,"file_name":"394-SGHE14.pdf","date_created":"2018-03-20T06:59:55Z","creator":"florida"}],"date_created":"2017-10-17T12:42:08Z","type":"conference","department":[{"_id":"66"}],"status":"public","has_accepted_license":"1","page":"180-195","_id":"394","ddc":["040"],"user_id":"477","file_date_updated":"2018-03-20T06:59:55Z","citation":{"mla":"Schwichtenberg, Simon, et al. “Normalizing Heterogeneous Service Description Models with Generated QVT Transformations.” <i>Proceedings of the 10th European Conference on Modelling Foundations and Applications (ECMFA)</i>, 2014, pp. 180–95, doi:<a href=\"https://doi.org/10.1007/978-3-319-09195-2_12\">10.1007/978-3-319-09195-2_12</a>.","bibtex":"@inproceedings{Schwichtenberg_Gerth_Huma_Engels_2014, series={LNCS}, title={Normalizing Heterogeneous Service Description Models with Generated QVT Transformations}, DOI={<a href=\"https://doi.org/10.1007/978-3-319-09195-2_12\">10.1007/978-3-319-09195-2_12</a>}, booktitle={Proceedings of the 10th European Conference on Modelling Foundations and Applications (ECMFA)}, author={Schwichtenberg, Simon and Gerth, Christian and Huma, Zille and Engels, Gregor}, year={2014}, pages={180–195}, collection={LNCS} }","ama":"Schwichtenberg S, Gerth C, Huma Z, Engels G.

Given a suitable decomposition of the graph, our algorithm runs in time $O(|E|)$ and is very easy to implement. Its divide-and-conquer approach allows for an effective parallelization. Note that a suitable decomposition can also be computed in time $O(|E|\\log{|E|})$ (or even $O(\\log{|E|}\\log^*{|E|})$ on an EREW PRAM using $O(|E|)$ processors). For the proof of the approximation ratio, we use a sophisticated charging method that uses techniques similar to amortized analysis in advanced data structures. On general graphs, the minimum linear arrangement problem is known to be NP-hard. To the best of our knowledge, the minimum linear arrangement problem on series-parallel graphs has not been studied before.","lang":"eng"}],"publication":"Proceedings of the 12th Workshop on Approximation and Online Algorithms (WAOA)","type":"conference","department":[{"_id":"79"}],"file":[{"file_id":"1381","content_type":"application/pdf","success":1,"relation":"main_file","date_updated":"2018-03-20T06:58:44Z","file_name":"397-WAOA14_01.pdf","file_size":365818,"access_level":"closed","date_created":"2018-03-20T06:58:44Z","creator":"florida"}],"date_created":"2017-10-17T12:42:09Z","has_accepted_license":"1","status":"public","ddc":["040"],"user_id":"15504","page":"168--180","_id":"397","project":[{"_id":"1","name":"SFB 901"},{"_id":"5","name":"SFB 901 - Subprojekt A1"},{"_id":"2","name":"SFB 901 - Project Area A"}],"file_date_updated":"2018-03-20T06:58:44Z","citation":{"mla":"Scheideler, Christian, et al. “Minimum Linear Arrangement of Series-Parallel Graphs.” <i>Proceedings of the 12th Workshop on Approximation and Online Algorithms (WAOA)</i>, 2014, pp. 168--180.","ama":"Scheideler C, Eikel M, Setzer A.

Previous work introduced access monitors attached to the memory subsystem to ensure that the cores adhere to pre-defined protocols when accessing memory. In this paper, we combine access monitors with a formal runtime verification technique known as proof-carrying hardware to guarantee memory security. We extend previous work on proof-carrying hardware by covering sequential circuits and demonstrate our approach with a prototype leveraging ReconOS/Zynq with an embedded ZUMA virtual FPGA overlay. Experiments show the feasibility of the approach and the capabilities of the prototype, which constitutes the first realization of proof-carrying hardware on real FPGAs. The area overheads for the virtual FPGA are measured as 2x-10x, depending on the resource type. The delay overhead is substantial with almost 100x, but this is an extremely pessimistic estimate that will be lowered once accurate timing analysis for FPGA overlays become available. Finally, reconfiguration time for the virtual FPGA is about one order of magnitude lower than for the native Zynq fabric.","lang":"eng"}],"file":[{"creator":"florida","date_created":"2018-03-20T06:57:44Z","file_size":404328,"access_level":"closed","file_name":"399-wiersema14_fpt_IEEE_approved.pdf","date_updated":"2018-03-20T06:57:44Z","relation":"main_file","content_type":"application/pdf","success":1,"file_id":"1380"}],"date_created":"2017-10-17T12:42:09Z","type":"conference","department":[{"_id":"78"}],"title":"Memory Security in Reconfigurable Computers: Combining Formal Verification with Monitoring","year":"2014","author":[{"id":"3118","full_name":"Wiersema, Tobias","first_name":"Tobias","last_name":"Wiersema"},{"first_name":"Stephanie","last_name":"Drzevitzky","full_name":"Drzevitzky, Stephanie"},{"last_name":"Platzner","first_name":"Marco","full_name":"Platzner, Marco","id":"398"}],"date_updated":"2022-01-06T07:00:05Z","language":[{"iso":"eng"}],"doi":"10.1109/FPT.2014.7082771","file_date_updated":"2018-03-20T06:57:44Z","citation":{"ieee":"T.

Scanning transmission electron microscopy (STEM) and spatially resolved cathodoluminescence (CL) at room temperature and at low temperature are used to characterize the optical properties of the cubic AlN/GaN MQW structures. An increasing CL emission intensity with increasing film thickness due to the improved crystal quality was observed. This correlation can be directly connected to the reduction of the linewidth of x-ray rocking curves with increasing film thickness of the c-GaN films. Defects like stacking faults (SFs) on the {111} planes, which also can be considered as hexagonal inclusions in the cubic crystal matrix, lead to a decrease of the CL emission intensity. With low temperature CL line scans also monolayer fluctuations of the QWs have been detected and the observed transition energies agree well with solutions calculated using a one-dimensional (1D) Schrödinger-Poisson simulator.","lang":"eng"}],"publication":"MRS Proceedings","type":"journal_article","department":[{"_id":"286"},{"_id":"15"}],"date_created":"2018-08-22T11:36:57Z"}]
