Preferred Supplier
JOANNEUM RESEARCH offers mask-less laser lithography for cost-effective, high-resolution sub-micro and microstructure fabrication. This digital process supports rapid prototyping and master fabrication for optics, microfluidics, and electronics, enabling flexible designs on flat and curved substrates with precision up to 300 nm.

Offering Description

Origination by mask-less Laser Lithography

Our unique mask-less laser lithography enables the low-cost production of novel and complex high-resolution sub-micro and micro-structures:

  • Master fabrication e.g. for UV-nanoimprint lithography, hot-embossing, high precision optical injection moulding, vacuum resin casting
  • a Rapid prototyping in Micro-Optics, Photonics, Microfluidics, Electronics and others

Several advantages can be realised:

  • Reduction of process time
  • digital, non-photomask-based production
  • quick and flexible to test and implement design changes
  • fabrication of microstructures on flat and curved substrates via 5-axes nano-positioning system

Applications can be found in

  • Free form micro optics for innovative illumination designs
  • Diffractive and refractive micro optical elements
  • Bionic surfaces in aviation for reduction of drag to reduce fuel consumption
  • Microfluidic Lab-on-Chip systems for molecular diagnostics
  • Micro-Electronics

Offering Specifications

  • High quality fabrication of sub-micro and micro-structures on large area formats (2″, 4″, possibly 6″ substrate)
  • Structures can have a 1D, 2D, or stepless (2.5 D) relief shape
  • Minimum structure size achieved in the lateral direction of our system is in the range of 300 nm
  • Maximum structure depth for 2.5D microstructures is in the range of 80 μm
  • Aspect ratio of 4 is possible
  • Depending on the complexity of the designed microstructure, the processing time is approx. 1 hour per cm2
