The Spirit of the NMJ Association

Key technologies in the fields of e.g. micro-electronics, medical implants, sensing devices and packaging have an urgent need for advanced joining technologies to integrate, package and assemble nano- and micro-scale materials and components at ever-lower temperatures. While micro-joining has already become one of the most critical technical prerequisites in the manufacturing of micro-devices and micro-systems, many technological advancements are still needed to allow faster and more reliable fabrication, continuing miniaturization and further cost reduction. The field of nano-joining is also evolving rapidly and is expected to become a key technology for the large-scale production and commercial application of nano-devices and nano-systems in the coming decades.


NMJ was born from the recognition by the joining technology experts, frequently meeting at IIW annual assembly (Prof. N. Zhou, University of Waterloo/Canada, Prof. Zuo, Tsinghua University/China, Prof. A. Hirose, Osaka University/Japan) of the need for a scientific exchange platform in the emerging fields of nano- and micro-joining technologies. With this aim the first conference Nano-/Microjoining Conference NMJ 2012 was held.


The NMJ conferences aim at exchanging scientific and technological knowledge about newest development in processes, materials, techniques and applications in the emerging field of nano- and micro-joining technologies. In particular, the following topics are in the scope of the NMJ conference series:

  • Joining for integration of nano-/micro-scale materials and devices (nano-micro-electronics, N/MEMS, sensors, medical instruments and energy-conversion systems)
  • Process issues in nano-/micro-joining (e.g. adaption of conventional processes, process control and new joining concepts)
  • Method development for nano-/micro-joint characterization (e.g. functional and mechanical properties, joint microstructure, integrity, reliability)
  • Fundamentals of nano-/micro-joining (e.g. bonding and interface reactions, size-effects, melting-point depression, self-propagating high-temperature synthesis, modelling)
