Patterning photonic crystal structures on the surface of LEDs is
one of the most promising ways to boost the efficiency. These
periodic structures, typically consisting of etched holes at the
surface, have periods in the 100-500 nm range. EULITHA has
developed a template to be used in high resolution patterning of
LED surfaces.
The template, consisting of pillars with a periodicity of 106 nm
on a silicon surface, is targeted for use in R&D studies. Areas
on the order of several square centimeters are covered by
step-and-repeat exposure of 1x1 mm2 dies. The combination of
resolution, quality and large areas make these unique templates a
perfect choice in the drive to fabricate ever more efficient
LEDs.
EULITHA was founded in 2006 in the canton Aargau of Switzerland.
Its founders have played critical roles in the development of
Extreme Ultraviolet Interference Technology at the Paul Scherrer
Institut. The company aims to serve nano-structuring needs of
targeted applications through this breakthrough technology. At
present, it provides products as samples for nanotechnology
R&D.
