Technology
Lasers are the tool of choice for many micro-structuring
applications:
- Ultra-high Precision - nanometer range etch rate and
encoder resolution
- High Flexibility - design changes can be implemented
in a cost- and time-effective way
- Scalability - in principle there are no limits to the
substrate size (proven up to Gen6: 2000 x 1500 mm)
- Simply the Best - in many cases there are no
alternative technologies, particularly for special feature geometries
on large areas
However, we don't restrict ourselves to using lasers. With our
background in mechanical materials processing we are happy to
consider alternative technologies or combinations of technologies
to find the optimum solution to meet your micro-structuring
challenge.
Achievable Characteristics

- Feature height or depth: < 1 µm – 250 µm
- Wall angles and slopes: 0° - 90°
- Fast micro-lenses f# < 1
- Any lens geometry (e.g. a-spherical, fresnel, elliptical)
- Large variety of optical geometries (e.g. moth eye, corner cube, prism)
- High aspect ratio features (4:1)
- Optical surface finish (RMS < 20 nm)
- Tight geometrical feature tolerances (±0.3 µm)
- 100% fill factor (any packaging, e.g. hexagonal, square)
- Large area processing (proven up to 2000 mm x 1500 mm)
- Process time: ~12h for 3 m2 area with 10 µm deep structures
