Fassi ITIA-CNR, Institute of Industrial Technology and Automation, National Research Council, Italy 1. Introduction In recent years, there is an increasing demand for small and even micro scale parts and this trend towards miniaturization makes the micro system technologies of growing importance. Microfabrication process capabilities should expand to encompass a wider range of materials and geometric forms, by defining processes and related process chains that can satisfy the specific functional and technical requirements of new emerging multi-material products, and ensure the compatibility of materials and processing technologies throughout these manufacturing chains. Example technologies to be investigated either individually or in combination are technologies for direct- or rapid manufacturing, energy assisted technologies, microreplication technologies, qualification and inspection methods, functional characterisation methods and integration of easy and fast on-line control systems. The processes should demonstrate significantly high production rates, accuracy and enhanced performance or quality, creating capabilities for mass manufacture of microcomponents and miniaturised parts incorporating micro- or nanofeatures in different materials. Processes should also provide high flexibility and seamless integration into new micro- and nanomanufacture scenario. Micro- and
