Although well noted as a winter play place with many alpine ski resorts nearby, Grenoble also offers numerous outdoor activities during the warmer parts of the year. The many universities located here add an intellectual and international feeling to this enchanting yet isolated city. Grenoble is home to one of the World Trade Centers and several strong international businesses. The Museum of Art and the many historical Napoleonic streets all contribute to the distinguishing character of this city. A mechanical lift takes visitors up the overlooking mountain to the old fort, offering a breathtaking view. The fort represents the highly interesting and important history of Grenoble during the Spanish Inquisition. After a full day of activities, visit either the Italian section on the left bank, or one of the many intimate and warm restaurants found along the narrow, old streets.

Le Téléphérique de Grenoble - Bastille
Since 1934, the Bastille site has been linked to the city by what at the time was Europe's first cable-car in a town centre. The short breathtaking ride in the "Eggs" sweeps visitors up to the viewing platforms, discovery trails around the fortifications, recreation areas, café, restaurant, footpaths and fitness circuits.
Fort de (la Bastille)
As early as 1934, La Bastille was connected to the city center by a teleferique. It was the first city teleferique in the world. A completely new teleferique was built in the 70s with 5 small cabins instead of a large one, locally known as "les Bulles" (the bubbles). The Bastille trip with the teleferique is a must. It offers a birds eye view on the roofs of the "quartier Saint Laurent", the oldest part of Grenoble and after a few minutes a panoramic view on the surrounding massifs and on the city. It is possible either to go down to the city by the teleferic or to take one of the trails that follow the fortifications and reach the valley.
Musée de Grenoble
Founded in 1796, this is one of the country's oldest art museums. It was the first French museum outside of Paris to focus on modern art, a fact appreciated by Picasso, who donated his Femme Lisant in 1921. The collection includes Flemish and Italian Renaissance works, but the Impressionist paintings generate the most interest.
Musée de l'Ancien Evêché
The fine collection of art here is made from wood and glass, which chronicles the historical development of the region's culture. Exhibits are further augmented by a series of photographs and brief documentaries.
Fontaine du Lion et du Serpent
Place de la Cymaise, Fontaine du Lion (Lion fountain), a bombastic statue by the sculptor Sappey and molted by Crozatier. It symbolize the fight between the winding Isère river (the snake) and its affluent, the torrential Drac river (the Lion), that has flooded Grenoble several times in the past. The snak is molted in bronze while the lion is carved in white lime stone from Sassenage.
Le Bois Francais Lake and Park
The park covers an area of 100 hectares and has a very large lake in the centre of it. There are a number of watersports on offer at the lake and there are always life guards on duty. The park has a number of facilities, including a swimming area; a beach area; canoeinf; water skiing; a cafe; picnic areas; fitness trails; and nature trails.
Chartreuse, Vercors and Belledonne mountains
Rooms have been reserved at the following hotels. When reserving a room please say you are attending the '4M Conference' as some of the costs listed are at a reduced rate.

Micro-manufacturing is now a key value-adding element for many sectors of industry - and the predicted nanotechnology future will also be largely delivered by micro-technologies. The silicon-based microelectronics revolution of the late 20th Century is about to be overtaken in its scope. Micro- and nanomanufacturing technologies in the 21st Century need to be directed to take advantage of the variety of materials, components and knowledge-based technologies now emerging. These provide functionality and intelligence to highly miniaturised systems for personal, portable and wireless products, and sensors for health, environment and transport-related applications. The present suite of micro-technologies alone will not be able to meet the manufacturing demands for high-aspect-ratio structures, enhanced-force micro actuators, improved environmental resistance and high precision micro components. These are the biggest challenges to micro product development that also represent promising research and development areas for innovation and value creation. In this context, the main goal of the Conference is to provide a forum for experts from industry and academia to share the results of their in-depth investigations and engage in interdisciplinary discussions about the creation of manufacturing capabilities for:
o Product miniaturisation through innovative integration and development of knowledge-based technologies and production concepts (especially micro and nano) for processing of non-silicon materials.
o Prediction of product and process performance to reduce/manage the risk during product development and production, and reduce time to market for the next generation of microsystems-based products.
o Future product platforms to meet the requirements of the next generation of microsystems-based products, and of more stringent regulations and environmental legislation.
o Production scale-up to ensure an effective and efficient transfer of product and technology ideas from laboratories to serial production.

Lab on a Chip : Advances in packaging for MEMS and Lab on a Chipa: CEA, LETI, Department Microtechnology for Biology and Health-care, France AbstractIn the field of bioMems or Lab on a Chip, one may have to handle fluid exchanges even at high pressure, moving parts, temperature sensitive probes. This specificity triggers huge packaging issues because most of the packaging techniques inherited from the microelectronic require thermal cycles at temperature above 350°C. In this paper, we first present the requirement of representative lab on chip projects carried out at the LETI in order to introduce two specific solutions of this field. Afterwards we present a brief review of the packaging processes used in the MEMS facilities eventually and introduce low temperature packaging processes developed at the CEA Leti to process lab on chip with MEMS and BioMEMS. We intend to develop robust and collective solutions (wafer level packaging). The first solution relies on a thin film approach develop for MEMS using silicon nitride cap on a sacrificial layer. The second one was especially designed for temperature sensitive lab on chips hence can be carried out at room temperature. Keywords: packaging, lab on chip, thin film, in line screen-printing |

Micro- and nano- structuring using ion beamsa: Eindhoven University of Technology, 5600 MB Eindhoven, the Netherlands AbstractIon beam techniques such as ion projection can be used to structure materials on micrometer and nanometer scales. It can complement current optical or e-beam lithography techniques for micro- or nanodevice fabrication. Besides ion beam lithography also direct ion beam structuring methods that do not rely on resist materials for the pattern transfer have been investigated. Local sputtering, magnetic nanopatterning and inducement of selective electroplating are examples for such resistless ion beam patterning techniques.

Micromoulding - Precision Processing for Controlled ProductsPolymer IRC/ Polymer CIC, School of Engineering, Design & Technology, University of Bradford, Bradford BD7 1DP, UK AbstractMicromoulding is an emerging field which has seen the evolution of conventional polymer injection moulding techniques for the manufacture of 3-dimensional components of sub-milligramme masses and/or microscale surface features. Micromoulding incurs extremely high strain rates and temperature gradients, particularly at the gate of the cavity. A range of issues associated with this, including high strain rate rheology of polymers (including experimental observation of in-cavity flows) and effects on orientation, residual stress and property developments, including surface replications have been explored in our laboratories and with collaborators. A major aim is to achieve controlled, repeatable dimensions and properties in micromoulded products, and to model this process - including molecularfeature models. The key factors determining control of precision products are discussed. Keywords: micromoulding, miniature, precision moulding |

Automatic Nanohandling Station inside a Scanning Electron MicroscopeDivision Microrobotics and Control Engineering, University of Oldenburg, D26111 Oldenburg, Germany AbstractCurrent research work on the development of an automated nanohandling cell in a scanning electron microscope (SEM) is presented. Two experimental setups are shown, in which nanohandling robots ooperate in the vacuum chamber of an SEM. A client-server control system that can integrate various microrobots and sensors has been developed and evaluated by automatic handling of TEM (transmission electron microscope) lamellae by two nanorobots. The robots are controlled in a closed-loop way by using images from several CCD cameras and from the SEM. Algorithms for real-time processing of noisy SEM images have been implemented and tested. The experiment on automatic handling of TEM lamellae inside an SEM is described. The other setup contains a nanohandling robot using the probe of an atomic force microscope (AFM) as an end-effector. The manipulation of individual multiwall carbon nanotubes (MW-CNTs) and the characterization of nanofilms by nanoindentation are the applications being investigated. The experimental setup includesf a nanopositioning piezo sample stage with three degrees of freedom (DoF) and a three-axes nanomanipulator. Piezoresistive AFM probes are applied as an end-effector. This way the acting forces can be detected allowing force feedback for the station's control system. First investigations have been carried out by bending of MWNTs and calculating their elastic modulus. Keywords: microrobotics, nanohandling automation, SEM image processing, nanocharacterization |

Replication of micrometric pattern by hot embossing of silica based feedstock AbstractThe CEA is developing a new forming technique derived from the hot embossing of polymers. This technique consists in replacing the polymer by a feedstock composed on binders and inorganic nanopowders. The process consists in three stages that are forming/pressing, debinding and sintering, similarly to the micro Powder Injection molding. This process has been optimized for the replications of micrometric patterns. This work has led to the development of a feedstock composed of water-soluble binder and nanometric fumed silica. It was possible to replicate gratings of ~1 micron after sintering. The replication of sub-micronic plots is not possible at this stage. It is expected that the use of smaller particle size could allow reaching this objective. Keywords: hot embossing, gratings, silica |

Force fields with one stable equilibrium for micropart 2D manipulation
AbstractThis paper proposes an approach for structuring a two dimensional (2D) force field with just one stable equilibrium at the desired location for the manipulation of microparts without sensing. The derived force field induces a unique stable equilibrium for any convex or non-convex polygonal micropart on the plane with arbitrary shape and size, where the equilibrium pose is the desired location of the micropart. Extensive simulations show the efficiency of the proposed method in the formulation of the force fields for 2D manipulation of microparts.

Off-Axis Machining of NURBS Freeform Surfaces by Fast Tool Servo Systems
AbstractThe manufacturing of optical components with complex geometries like freeform surfaces is getting more and more important. Mass production of these optics is enabled by replication methods like injection moulding. For the machining of the required mould inserts with freeform geometries ultraprecision technologies like Fast Tool Servo turning can be applied to achieve the appropriate optical surface quality. For the mathematical description of freeform surfaces NURBS (Non Uniform Rational Basis Splines) are highly applicable. To avoid interpolation errors and to create set points with a continuous and smooth path of motion a trajectory generator directly based on NURBS data has been developed for Fast Tool Servo assisted turning [1], which evaluates the NURBS surface in each position control cycle. An approach of increasing the efficiency of manufacturing freeform surfaces is the off-axis machining of multiple workpieces at the same time. The paper presents the different process steps in simulation and off-axis machining of freeform surfaces using Fast Tool Servo assisted turning in conjunction with NURBS based data processing.

Laser transmission welding of micro plastics partsE. Haberstroh, W.-M. Hoffmann AbstractOnly few welding processes for plastics meet the special demands of microtechnology. Laser transmission welding has distinctive advantages like low mechanical and thermal load of the joining parts. Thus the laser is a joining tool which is particularly suitable for the welding of micro plastics parts. Contour welding is a process variant of laser transmission welding enabling the welding of complex and even three-dimensional weld contours. In addition to that, this is a very flexible process which can be easily adapted to changing part geometries. So far it is only applied for welding plastics parts of macroscopic scale in the industrial practice. Recent research at the Institute of Plastics Processing in Aachen shows that it is also possible to use this process to weld filigrane micro parts. Thus another promising welding process has proven its suitability for the microtechnology. Welding trials with different thermoplastics show, however, that there are big differences in the material behaviour that make some platics more suitable than others for the contour welding in microtechnology.

Prototyping of multilayer waveguides with V-grooves in COC/Topas®
a MIC - Department of Micro and Nanotechnology, Technical University of Denmark, b HSG-IMIT, Institute for Micromachining and Information Technology,Villingen-Schwenningen, Germany c IMTEK - University of Freiburg, Laboratory for MEMS Applications, AbstractA number of fast and low-cost methods are used for prototyping of optical waveguides in the cyclic olefin copolymer Topas®. This polymer has a number of advantages compared to polymers traditionally used for micro systems. The advantages include good chemical resistance, good optical properties, and low water absorption, making it well-suited for lab-on-a-chip systems. Using micro milling, spin coating, and thermal bonding, and exploiting the different refractive indices of different grades of Topas®, waveguides with a width and heigth of 130 μm are created. 45° V-grooves at both ends of the waveguides are used for coupling light in and out of the waveguides, using the principle of total internal reflection. In this manner light can be coupled into the waveguides perpendicularly from above or below the structure, depending on the groove orientation. This coupling scheme has a large potential for rotating microfluidic system, the so-called lab-on-a-disk systems. Keywords: COC/Topas®, micro milling, waveguides, prototyping, V-grooves |

In-process assembly of micro metal inserts in a polymer matrix
Department of Manufacturing Engineering and Management, Technical University of Denmark, AbstractNew functionalities and smaller dimensions of micro products can be achieved by means of a higher degree of integration of both materials and components. Smart micro assembly techniques (such as on-the-machine assembly) together with hybrid structures (as metal inserts in polymer matrix) are suitable solutions to manufacture new micro products with several integrated functionalities, reduced number of components and assembly phases, as well as the possibility to be replicated in a high number of specimens. Innovative manufacturing systems, as well as new design rules and testing methodologies, have to be established in order to be able to develop new and more integrated micro products. In this paper a method for testing the bonding between micro thickened metal inserts and the polymer matrix they are moulded in is presented. A specific demonstrator has been manufactured by means of a hot embossing-like process which allows fast developing time and the possibility of batch process. Different levels of surface roughness and metal insert thickness were applied in a systematic design of experiments. The results show a strong influence of surface texture on bonding strength. The testing procedure assists the designer in giving data to be used when dimensioning micro products involving integrated metal parts in a polymer product.

Low Temperature Adhesive Bonding in MEMS
AbstractA new concept for adhesive bonding of components with dimensions less than 300 μm in complex 3D structures is presented in this paper. Two different kinds of adhesives - polyurethane adhesive foil and polyethylene hot melt glue - were applied to the basic substrate by different techniques. The focused stream of hot gas directed to the substrate softens glue which had been applied as a solid. Afterwards, micro-parts were embossed in the softened glue, or covered and shielded by it. After cooling down at room temperature, a rigid and compact bond was formed. The parameters which induce the heat transfer and the process performance generally are considered through various experiments. The advantages of this new approach are compact system which can be easily integrated in existing production lines, low capital costs, partial reversibility, applicability to many material combinations, localized heating with reduced thermal stresses, etc. In order to confirm the advantages of proposed bonding technique, a single mode glass optical fiber (core diameter 9 μm; cladding diameter 125 μm) was positioned in V-grooves to achieve requested alignment and positioning precision. V- grooves were made by chemical etching of silicon in the “111” plane. Bonding glass to glass was also successfully demonstrated. Keywords: adhesives, low temperature bonding, hot gas stream |
