Microprocesses and Nanotechnology play an important role of technical backbone for constructing the advanced information communications society with ubiquitous net works of the 21st century. The MNC conference is now in its 26th year and is intended to provide a forum for discussing lithography science and process technology using photon, electron, ion, other energetic particles and nanomaterials. This conference covers not only their applications to micro-and nano-structure fabrication and related physics and devices, but also their fusion applications with other fields like bio, medical information, and communication technology.
