micro resist technology offers functional materials for Inkjet-printing. The materials have been specially designed to exhibit a good compatibility to a broad range of inkjet printing tools.

The portfolio involves two classes of products providing ideal solutions for the manufacture of micro and nano optical components or functional films. InkOrmo is a  transparent hybrid polymer exhibiting excellent optical properties as well as high chemical, mechanical and thermal stability. mr-UVCur26SF is a transparent solvent-free material which has been specifically designed for nanoimprint lithography (NIL).

 

Example for Injetprinting

Process

A) Microlenses by inkjet printing:

  • Typical lens size ranges from 50 µm to 1000 µm, but not exclusive
  • Lens aspect ratio (height/diameter) controlled by substrate pre-treatment
  • Lens profile with high level of freedom possible based on pre-patterned substrate
  • Lens size (diameter & height) controlled by printed volume / lens

B) Nanoimprint-lithography:

  • Step&Repeat process and continuous roll-to-roll (R2R ) UV-NIL processes
  • Large-area nanostructuring of flexible substrates
  • Ultra-high photocuring rate enabling high roller speeds and high throughput
  • R2R web speeds up to 30 m/min demonstrated

Special Features

  • Compatible with commercial inkjet printing devices
  • Optimized for UV- Nanoimprint lithography
  • UV-curable solution
  • Solvent-containing and solvent-free inkjettable materials

Applications

  • Optical components (transparency)
  • Packaging (chemical inertness and optical and mechanical stability)
  • High volume manufacturing of antireflective coatings, (super)hydrophobic patterns on flexible substrates and wire-grid polarizers
  • Etch mask for plasma etching (excellent dry etch stability for pattern transfer)
