TEMPLATE-ASSISTED DEPOSITION OF FUNCTIONAL MATERIALS AND DEVICES

Final Report Summary - TEMADEP (TEMPLATE-ASSISTED DEPOSITION OF FUNCTIONAL MATERIALS AND DEVICES)



Executive Summary:

The TEMADEP project has been an excellent opportunity for fruitful collaboration between partners. They have been involved in secondments, meetings international workshop, organized in Belgium, Lithuania, Moldova and France. Outstanding research has been done in order to understand interdependencies between structure and properties of tungsten and molybdenum alloys, as well capability and competence to implement achieved results by networking with other institutions, namely Universitat Autonoma Barcelona (UAB) and IMEC, which is in the line with one of the project objective - strengthen the EU expertise and establishment of cooperation in the field of nanomaterials and nanodevices. Thus, the project efforts were combined to study nanostructured materials consisting of iron group metals alloys that are especially appropriate for use in microelectromechanical systems (MEMS) where microstructures with high mechanical strength and wear resistance coupled to a high thermal resistance and stability against plastic deformation are required. Of main interest was producing of nanowires and heterostructures (multilayers) obtained by electrochemical ways and the relationship between structural properties and synthesis conditions. These nanomaterials were optimized to achieve the pre-requisites for MEMS electroforming, e.g. in collaboration with IMEC, in the view of microbumps application. Also, template-assisted electrodes for sensors were electroformed. These electrodes consist on the array of “nanomatches” having shank of Co-W alloy (2 m length and 100 nm in diameter) and golden head (50 nm in diameter). The maps of the corrosion behaviour and magnetic properties of the most promising Co-W alloys was created based on the study of a number of alloys having different content of W (0-31 at.%) and structure (polycrystalline and “amorphous-like).

Another key objective – intensification of cooperation between member states (Belgium, Lithuania and France) and Third countries (USA and Moldova) in the area of nanostructured template-assisted materials was also successfully achieved, by joint scientific activities and publication of joint papers in journals with impact factor. Partners were also active in creating new opportunities for a further exploration of materials science:

a) By submitting 5 projects in the framework of FP7 program: MRC-IAP (ERA-WIDE), Oil&Sugar (IRSES), EC-MODEL and IAPSEC (2 REGPOT), INOUT-transResearch (CIG Marie Curie Actions) and preparing new ITN project within Marie Skłodowska-Curie Actions in Horizon 2020;
b) By submitting 4 bilateral and national projects: SCOPES, Ukraine - Moldova, Lithuanian Science Council Foundation, and Moldovan National Foundation.
