Rainbow holograms design, optimization and fabrication at KERI
International team consisting of specialists from KERI Nanocenter (Miryang,
Rep. of Korea), from 3SMK (Seoul, Rep. of Korea), from Interface (Moscow, Russia)
and from IMT RAS (Chernogolovka, Russia) were successful in design, optimization
and fabrication of high quality rainbow holograms. The rainbow holograms consist
of diffraction gratings of variable duty cycle with a minimum stroke size of
50 nm. These gratings cover the whole area of the cylindrical stamp.
"RainBow" software for hologram design/optimization and lithographic
data preparation (Interface, IMT RAS)
original technology for metal stamp fabrication (cylindrical technology,
homemade (KERI) original technology for imprinting in plastic media
The technology jointly developed has a set of advantages in comparison:
to common optical (dot-matrix) method as producing holograms of higher quality
to usage of industrial e-beam lithography systems as much more cost effective
As result Korean parties (KERI NanoCenter and 3SMK) have leased out "RainBow"
software and in their part Russian partners performed training to hologram
design/optimization and provided support for e-beam lithography.

highest quality (with stroke width from 50nm) on a cylindrical mold (with
area about 30 cm by 30 cm).
Nano Process Research Center is a division of the Korea Electrotechnology
Research Institute (KERI) in Miryang (Rep. of Korea). Center researches in
the field of fabrication and the associated process system of a large area
nano cylindrical mold which is the core technology for nano printing technology.
The main research topics are cylindrical nano lithography utilizing magnetic
levitation, cylindrical plasma nano-etching, and the application technologies
utilizing nano cylinder mold.
