MULTILAYER · Rolled multi material layered 3D shaping technology

Various emerging markets in the field of non silicon multimaterial micro devices offer a huge potential for commercialisation in the near future. However, solutions for mass-production for most of them have still to be developed. The objective of the MULTILAYER project is to develop a set of solutions for the large-scale production of micro devices based on a technology we call “Rolled multi material layered 3D shaping technology” and using the concept of tape casting and advanced printing techniques. This technology will enable to manufacture complex multifunctional 3D-micro parts on a layer by layer manner and in a high-throughput context. Each layer can be given a specific structure. They will be printed and contain channels and cavities that are open or filled in a very high precision manner. The microsystems will have as basic building material ceramics, which is a clear advantage in applications that require high temperature, corrosive environments and long time reliability. Furthermore, it will allow spatial resolutions under 10 µm and the ceramics tapes developed will be down to 10 µm thin. The “Rolled multi material layered 3D shaping technology” will have several advantages: - it will be an efficient mass production method - the fabrication series can attain over a million units - it will offer a good flexibility for a wide variety possible component designs, - it will allow the integration of different materials as different layers enabling to manufacture multimaterial multilayered packages with a high degree of integration, - the process will be very reliable, indeed, every single layer can be advantageously inspected and controled
