 ntributing to our modern life as been used in IC chips\, computers\, smart
 phones\, flat displays\, game machines\; even recent appliances and automo
 biles are fully equipped with advanced nano-devices and nano-materials.  
 However\, most of existing nano-fabrication technologies are limited to th
 e modification of surfaces or thin films of the materials in two dimension
 s\, where e-beam\, ion-beam\, and photon are used.  Electronic nano-circu
 its\, high-density data storage\, liquid-crystal displays\, and MEMSs and 
 NEMSs are all basically in two dimensions.  In this presentation\, I woul
 d like to discuss the methods of real three-dimensional nanofabrication wi
 th laser-beam drawing combined with two-photon polymerization for 3D micro
 - and nano-machines [1]\, two-photon isomerization for 3D rewritable optic
 al data-storage [2]\, and two-photon photo-reduction for 3D metamaterials 
 [3].  For fabricating large-scale complex structures\, self-growth techno
 logy has been successfully utilized\, such as self-grown fiber structures 
 of polymer [4] and self-grown metallic fractal metamaterials structures [5
 ]. \n\nBio: Professor Satoshi Kawata has been a Professor of Applied Phys
 ics at Osaka University\, Japan since 1993. He has been also a Chief Scien
 tist at RIKEN from 2002 to 2012\, and a Team Leader till 2015. He is now t
 he Professor Emeritus and the Founding Director of Photonics Center (PARC)
  of Osaka University\, and the Honorary Scientist of RIKEN. He started up 
 a laser-scanning Raman microscope company\, Nanophoton Corporation (www.na
 nophoton.net)\, in 2003\, where he is now the chairman of the board.  He 
 has served as the President of Japan Society of Applied Physics (JSAP)\, t
 he President of Spectroscopical Society of Japan\, and the Editor of Optic
 s Communications\, and Directors of many societies.  Professor Kawata has
  invented a number of new concepts in photonics\, including aperture-less 
 near-field scanning microscopy\, evanescent wave photon pressure\, optical
  CT microscopy\, plasmon holography\, tip-enhanced and deep UV Raman micro
 scopy\, two-photon nano-fabrication. He is a Fellow of OSA\, SPIE\, IOP\, 
 and JSAP.\n\n[1]        S. Kawata\, et. al\, Nature 412\, 697−698\
