SEAL is a project for an integrated project consisting of 17 equipment assessment sub-projects in the area of semiconductor manufacturing equipment. The assessment themes are equally spread amongst processing and metrology equipment, heading beyond the current state-of-the-art both for More Moore and More than Moore applications. The strategic objective of SEAL is to effectively combine efforts, resources and expertise in the joint assessment of novel equipment supported by cross-cut R&D dedicated to the identified needs of the assessment sub-projects.For Lithography, the key areas of illumination systems for mask aligners, EUV mask manufacturing and intelligent overlay management are addressed as well as massively parallel e-beam lithography. In addition, three important processes are addressed: low temperature oxidation, cleaning of sensitive interconnect stacks/structures and ion implantation for ultra shallow junctions and defect engineering. For metrology and analysis, the main focus is on enabling innovative systems to efficiently contribute to at-line and in-line monitoring and control within semiconductor facilities. Without such equipment, it will not be possible to validate progressively advanced processes during development and manufacturing.Cross-cut R&D activities relating to all equipment assessment sub-projects are covered including APC, model based control, equipment simulation, enhanced wafer and equipment logistics, advanced communication and man machine-interfaces, and virtual equipment engineering. A common approach for the assessment activities will be utilised with specifications that will be refined for each equipment type for the progressively emerging technology nodes.Overall, SEAL will strengthen the European equipment manufacturing industry in an ideal and sustainable way by combining advanced R&D topics in equipment sub-projects involving a wide community of users, research institutes and equipment suppliers with many SMEs.

The objective of the project COTECH is to investigate new approaches of -manufacturing based on advanced technology convergence processes and to propose hybrid solutions for high added value cost effective -manufacturing emerging applications. The main goals of COTECH are to develop: (1) -replication technologies underpinned by emerging tool-making technologies for processing multi-material components and creating: a) 3D -components using high throughput multi-material -injection moulding with sub-m resolution; b) 2D -components using direct multi-material hot or UV embossing with a sub-200nm resolution. (2) Radically new replication convergent technologies combining the capabilities of -injection or embossing to a complementary activation step to create intelligent devices in a single process step: a) Hybrid processes based on -injection moulding using modules of e.g coating and compression injection moulding, to provide functionality to -devices, such as active coatings and combination of micro and nano features in a single step; b) Ultimately the hybrid processes based on -injection with embossing will be validated. This will offer a very high throughput multimaterial -injection that will enable the fabrication of 3D high aspect ratio -parts, complemented by an embossing step to allow ultra precise 2D features. (3) Global process chains with increased MTBF (50%) and fabrication of high quality products. This requires innovative non-destructive inspection solutions and simulation models. (4) High added value -devices with advanced functionalities. COTECH proposes to validate industrially the new technology convergence processes with 8 demonstrators representing the most emergent industrial sectors (transport, biomedical, energy). The expected market for the industry exceeds 1 Billion . COTECH will also address the problem of knowledge fragmentation by activating a polymer -manufacturing sub-platform as support to MINAM.

SEA4KET (Semiconductor Equipment Assessment for Key Enabling Technologies) is an IP proposal taking the consequent step from equipment R&D to equipment assessment experiments. The strategic objective is to effectively combine resources and expertise in a joint assessment of novel equipment for key enabling technologies to foster and accelerate the successful transfer of novel European equipment into the world-wide market.\nSEA4KET builds on the proven principle established in previous European SEA programs and projects: to take novel, innovative and promising equipment that has left the R&D phase into a joint assessment activity this bridges the well-known gap between the phase of having an engineered tool available and finding the first user and finally success in the market for it.\nWhile proven principles from previous SEA activities are kept, SEA4KET takes them to the new field of assessing equipment for Key Enabling Technologies: SEA4KET concentrates on process and metrology systems for important enablers of future technologies: 450 mm wafer equipment, SiC material and 3D processing. The proposal comprises 15 sub-projects each dedicated to a specific equipment. The assessment activities were to a lesser extent chosen by high S&T excellence, but by their expected chance on the market.\nWhile leading R&D institutes are active in each assessment experiment to support individual final developments, several cross-cut R&D activities were identified (and combined in a dedicated sub-project) that are relevant to multiple assessments. Training material will be provided and workshops will be organized, to support and strengthen the individual dissemination activities.\nSEA4KET will significantly strengthen the European equipment and material industry for the emerging market for Key Enabling Technologies in a sustainable way by combining advanced R&D with equipment assessment involving users, institutes and equipment suppliers with specific benefit for SME suppliers.

This paper proposes a new model for cluster tools with two load locks. Cluster tools are widely used to automate single wafer processing in semiconductor industry. The load locks are the entry points into the vacuum of the cluster tool's mainframe. Usually there are two of them available. Each lot being processed is dedicated to a single load-lock. Therefore at most two different lots (with possibly different processing times and qualification) can be processed simultaneously. This restriction is one of the major potential bottlenecks.Capacity planning is one of the possible applications for the proposed model and the paper demonstrates the integration into a more general framework that considers different tool types and different operational modes.The paper also generalizes an earlier model that is limited to three processing chambers. The proposed modeling approach is based on makespan reductions by parallel processing. It turns out that the performance of the new approach is similar, when compared to the generalized model for three chambers, but the new approach computationally outperforms the generalized model for four and more chambers. © 2017 Elsevier B.V.

Space activities and applications play an important role in strengthening the competitiveness of Europe by scientific progress in the knowledge-based society, and by providing strategic influence and security. Major successful space missions under European leadership have placed ESA and its Member States, the European science community at the forefront. To continue this path Europe must have independent and competitive access to space. With the ITAR (International Traffic in Arms Regulations) continuing to impede the acquisition of US components, Europe thus needs to develop an assured independent source of propulsion components. Today space craft propulsion relies heavily on toxic and carcinogenic hydrazines as propellants. Hydrazine itself is widely used as monopropellant and MMH and UDMH is used as bipropellant fuel. These propellants are a threat to people and the environment, and handling these toxic propellants impedes costly safety measurers. As new ideas and new technologies emerged in the last years, and as the concerns about both the environment and the handling of carcinogenic propellants significantly increase, the so-called Green Propellants show potential improvements with respect to performance and cost. The goal of this project is thus to select the most promising green liquid propellant candidate/s and to push the propulsion technology to the level needed to prove that Green Propellant technology is feasible and competitive. Research and development on Green Propellants and adjacent propulsion technology in Europe is geographically fragmented and insufficiently funded. With the present consortium, some of the key-players in Europe will harmonize their capabilities to meet this demanding goal.

In the proposed contribution the effect of the shear correction function is originally studied and evaluated in modal analysis of the functionally graded material (FGM) beams. Spatially continuous variations of the material properties are considered. The shear correction function is calculated from the shear strain energy equation including spatial Poisson′s ratio variations. The equations of the homogenized FGM beam free vibration and their solution is presented including the shear correction function. Four coupled differential equations are derived and used in the modal analysis of beams with polynomial continuous longitudinal and transversal variations of material properties. Further, 2nd order beam effects and longitudinal varying elastic beam foundations are considered. The influence of using an average shear correction factor is evaluated through numerical experiments. Additionally, the longitudinal eigenfrequencies are calculated. Continuum solutions using solid finite elements are taken as a reference for comparison purposes. © 2012 Elsevier Ltd.

Shell-like and beam structures made of Functionally Graded Materials (FGMs) show a gradual variation of material properties in one, two or three directions. In this paper an efficient low-order shell element with six nodal degrees of freedom (including the drill rotation) is presented, supplemented with a proper method for calculating effective elastic properties. This new FGM shell element is coupled with 3D FGM beam elements and combined elastostatic beam-shell structures are analyzed. The results indicate high a effectiveness and accuracy of the proposed approach. © 2013.

The possibility of replacing presently used highly toxic propellants by so-called Green Propellants has captured the attention of research groups as well as of the relevant industry worldwide. And indeed the potential of Green Propellants seems inspiring. The lower level of toxicity reduces the risk for personnel handling such propellants and therefore allows simplified and more cost efficient handling procedures. A variety of authors have outlined other areas of possible cost reduction when using propellants with a lower toxicity level. This includes a simplification of the propellant logistic and storage, fueling infrastructures at the launch pads, and propellant procurement to name only some. Most authors have focused on one particular Green Propellant in their experimental work and outlined the characteristics and benefits of it. Although very promising results have been reported, Green Propellants in general have up to now failed to generate a confidence level sufficient for the major industry to initiate first steps to implement them into a commercially available propulsion system. Contributing to this hesitation is the lack of a comprehensive effort to investigate Green Propellants and to provide industry with information they can use to re-evaluate their future strategy in respect to Green Propellants. For this reason a European consortium, financed by the European Commission in the 7th Framework Program (FP7) and consisting of 11 entities from 7 European countries, was established. The project, "Green Advanced Space Propulsion" (GRASP) aspires to provide such an information background. In the first phase of the project, GRASP has compiled a data base of more than 100 Green Propellant. This data base contains physical properties as well as information with regard to the individual toxicity levels and performance data. Based on this data base a preliminary selection was conducted to identify the most promising Green Propellant candidates. In the present phase of the project those candidate propellants are experimentally investigated to further down-select the candidates. The present paper provides an overview of the GRASP activities and discusses the selection process and the GRASP objectives in general and test goals obtained up to now in particular. © 2011 by Carsten Scharlemann.

Tuned liquid column gas damper (TLCGD) show excellent vibration absorbing capabilities appropriate for applications in wind- and earthquake engineering. However, in the early regime of strong motion seismic excitation or to counteract strong wind gusts the performance of the passive device can be increased substantially by active elements obtained from adding a pressurized gas supply with input-output valves to the sealed ends of the TLCGD. To prove the working principle of active TLCGD several small scale laboratory experiments have been performed with single and multiple degree of freedom host structures. To obtain a desired dynamic behavior, a conventional feedback control law is used to compute small active pressure inputs to the TLCGD. The experiments have proven that the active device is able to substantially reduce the dynamic system response in a broad frequency range. In fact, dangerous structural resonances of lightly damped structures can be avoided even if the passive absorber is not tuned perfectly. For multiple degree of freedom host structures a suitable control enables a single active TLCGD to counteract several modes of vibrations thereby avoiding the need to install numerous passive devices. © The Society for Experimental Mechanics, Inc. 2015.
