Abstract:

This Action will bring together all major groups in Europe working on a range of model reduction strategies with applications in many domains of science and technology. The increasing complexity of mathematical models used to predict real-world systems, such as climate or the human cardiovascular system, has led to a need for model reduction, which means developing systematic algorithms for replacing complex models with far simpler ones, that still accurately capture the most important aspects of the phenomena being modelled.

The Action will emphasize model reduction topics in several themes:

design, optimization, and control theory in real-time with applications in engineering;

data assimilation, geometry registration, and parameter estimation with a special attention to real-time computing in biomedical engineering and computational physics;

real-time visualization of physics-based simulations in computer science;

the treatment of high-dimensional problems in state space, physical space, or parameter space;

the interactions between different model reduction and dimensionality reduction approaches.

The focus of the Action is methodological; however, a wide range of both scientific and industrial problems of high complexity is anticipated to motivate, stimulate, and ultimately demonstrate the meaningfulness and efficiency of the Action.

Abstract:

The main objective of this project consists in the manufacturing of the first temperature sensor based on a SAW type device on AlN/Si. The sensor is based on the variation of the SAW resonance frequency vs. temperature. The sensor will be characterized ”on wafer” in the 25-150 oC temperature range. The sensor structures mounted on a special ceramic carrier, provided with SMA connectors and cables, will be characterized in the 5-500 K temperature range inside a cryostat. We aim to obtain a sensitivity >75 ppm/oC (on-wafer measurements) and 60 ppm/ oC for measurements with connectors and cables, in the 23-150 oC temperature range.

The project corresponds to the world wide effort to obtain acoustic devices operating in the gigahertz frequency range, using wide band gap semiconductors (AlN, GaN). These materials have very good piezoelectric properties. High quality GaN and AlN layers grown or deposited on Sapphire SiC or Si substrate permits to use in the fabrication protocol nanolithography, micromachining techniques and monolithic integration. The advantage of using AlN for the SAW structure consist in the possibility to obtain a higher resonance frequency and a higher sensitivity for the sensor. The project has few objectives beyond the state of the art.

The main element will be a SAW structure on AlN/Si with the resonance frequency in the 6-9 GHz range. The highest resonance frequency obtained up to now for SAW structures on AlN/Si is 5.1 GHz and was reported by the IMT and INCD-FM groups, partners in this project, using an IDT structure with digits and interdigit spacing 300 nm wide. This project requires interdigitated transducers having the digit/interdigit spacing 80-150 nm wide, a challenge due to the major difficulties of the nanolithographyic process on materials like AlN or GaN. Up to now, the narrowest lines on AlN have been reported on an AlN/Diamond based SAW structure in 2012 (200 nm).

For the proposed sensor a „single resonator” structure will be developed. Compared with classical structures based on face-to-face resonators and delay lines, the single resonator structure offers few advantages: higher quality factor, lower losses and mainly, higher values for the sensitivity, as it was recently proved by IMT for GaN.

A two steps, low temperature, deposition process will be developed, for the synthesis of thin AlN films. The goal is to lower the FWHM of rocking curve at 1.5° for the AlN films deposited on Si.

There is a potential advantage of monolithic integration of the SAW based AlN temperature sensor in a CMOS ICs. AlN technology is CMOS compatible, due to its low deposition temperature. In such circuits fabrication protocols contain nanolithographic processes, therefore these processes for the sensor will not add significant costs.

The project consortium consists in four teams with excellent expertise and complementarity in the project topics. The IMT team has many contributions in the state of the art for acoustic devices on GaN and AlN, in nanolithography and microwave characterization. INCD-FM has an excellent expertise in high quality AlN films deposition. UPB has excellence expertise in design and modelling of high frequency devices and circuits. ROMQUARZ is the only Romanian enterprise with an authentiq experience in SAW type devices manufacturing on classical piezoelectric materials.They have been involved in SAW devices manufacturing on non-semiconductor materials (quartz, lithium niobate, etc) in the last 20 years.

Abstract:

The topic is related to the 2012 work programme for ICT of the European Commission which emphasizes the need for more integration on functionalities on chips, requiring new software development technologies and parallelisation tools. The main goal is the development of knowledge in the RF-MEMS domain by fundamental and applicative research finalized with a new modelling methodology validated by experiments, aiming to efficiently couple electromagnetic, mechanical and fluid flow phenomena for the design of RF-MEMS switches. Models of manageable size for a set of benchmarks will be manufactured and characterized. The models will account for the dependence on relevant design or operating parameters and their behaviour will be experimentally validated.

Depending on the complexity of the structures and on the target applications certain steps in the fabrication process can suffer modifications (e.g. deposition of a Benzocyclobutene (BCB) layer on the Silicon substrate, BCB representing an important determinant of package reliability), which could represent a novelty for the technological process. The target is to obtain a functional switch that can be further integrated. The structure of the switch beam must be chosen so as to produce the lowest possible insertion loss (less than -1 dB), the highest possible isolation (more than 20 dB at 20GHz), lowest possible actuation voltage (25 - 30 V) that operates up to 60 GHz. The project aims to demonstrate potential benefits of using supercomputing in the design of RF-MEMS devices, improve design capabilities for RF-MEMS MMIC technology in Romania and achieve an efficient transfer of knowledge in both directions between a research institute which is more industry oriented (IMT) and a university team specialized in high frequency modelling and high performance computing (UPB).

Abstract:

Performing the step from micro- to nanoelectronics, the semiconductor industry is confronted with very high levels of integration introducing coupling effects that were not observed before. The complexity of this problem is beyond the possibilities of the software and design environments used within the microelectronics industry at present. Furthermore, it places additional requirements on the researchers of the future, since they must be able to understand all aspects of the problems faced by the industry.

To meet these new scientific and training challenges, the COMSON consortium on "Coupled Multi-scale Simulation and Optimisation in Nanoelectronics" merges the know-how of the three major European semiconductor industries with the combined expertise, in al l fields of interest, of specialized university groups for developing adequate mathematical models and numerical schemes, and realizing them in a common demonstrator platform: on the one hand, to test mathematical methods and approaches, so as to assess whether they are capable of addressing the industry's problems; on the other hand, to adequately educate young researchers by obtaining immediate hands-on experience for state-of-the-art problems.

Abstract:

The proposed project is highly inter and multi-disciplinary being associated to the technological platform of nanoelectronics (www.cordis.lu/ist/eniac). The research domain Electronic Design Automation - EDA is of utmost importance for the progress of nanoelectronics and it is based on interdisciplinary areas: "Scientific Computing in Electrical Engineering - SCEE" and "Computational Science and Engineering - CSE". Consequently, these are the areas in which research has to be carried out in order to obtain the desired progress in nanoelectronics. The research methods envisaged are: theory, computer simulation and experiment. The activities are not only related to research, but they also include transfer of knowledge and innovation at the highest level. The proposed project is part of a coherent and complementary series of European projects related to nanoelectronics, which are completed, or already selected to be financed or they are still in competition, at the first or the second stage.

The proposed research project aims to attract and train young PhD Romanian students in the domain of the development of new EDA tools for nanoelectronics, considering that the other projects allow the financing of foreign researchers that undergo doctoral studies in Romania. Another expected effect is the structuring at national level by means of support actions for the scientific community interested in the development of ED tools, the increase of the competitiveness of the Romanian industry of high-tech software development (EDA) and its access to the technological platform ENIAC and to FP7. Without consistent research, training and transfer of knowledge effort, we cannot imagine how else to achieve this goal. The project will enlarge the EDA reservoir of new models, theories, methods and techniques. Each project in the series has got a specific role, and moreover, the synergy between them adds extra value, for instance by using the experimental results obtained in one project into the other projects or by blending the research with the PhD training. Together with our European partners, the research goal is the development of appropriate mathematical models, numerical schemes and their implementation in a demonstrator software platform, called nEDA, dedicated to complex problems of nanoelectronics. The platform will allow the coupled simulation of semiconductor devices, interconnects, circuits, electromagnetic field and thermal effects, in a conceptual unitary frame. The nEDA platform will allow the comparison between simulation and measurements as well, in order to validate the newly developed methodologies, by using carefully chosen test structures. The results of the studies carried out on the nEDA platform will be a new methodology, validated by experiment, for the automatic extraction of compact models for RFIC functional nano-blocks, valid up to frequencies of 66 GHz. The implementation will be carried out using software tools able to generate SPICE models automatically, starting from the layout description, taking into account effects so far neglected. In this way, the research will contribute to the new generation of nanoelectronics design technologies, which will be robust, effective; it will allow design validation and the decrease of the design time and costs.

Project website: https://cordis.europa.eu/project/id/IST-2001-34058

Abstract:

The main goal of the CODESTAR project is the development of a code dedicated for the electromagnetic simulation of passive on-chip structure resulting in a small simulation network. First a detailed analysis of the test is carried out using an electromagnetic field solver. The outcome of the field solver is a full net list describing the detailed characteristics of the passive structure. This net list will be too large to be useful and therefore a systematic reduction of the net list must be done (i.e. reduced-order modelling). The resulting compact equivalent lumped-element model is inserted back into the full design scheme and the design cycle can be pursued. Parallel fabrication, characterisation and evaluation of dedicated test structures is carried out, in order to validate the CODESTAR code. The matching between experimental and CODESTAR simulation results is the measure of the project success.
