mr-UVCur26SF

Photo-Nanoimprint Lithography

mr-UVCur26SF is a pure organic and solvent-free Photo-NIL resist developed for inkjet dispensing. The low viscosity and the fast photo-curing reaction makes mr-UVCur26SF suitable for continuous roll-to-roll NIL processes.

Unique Features

  • Inkjet dispensing at room temperature due to low viscosity (15 mPas), e.g. for step-and-repeat NIL processes
  • No prebake after substrate coating due to solvent-free resist formulation
  • Very fast curing for high throughput R2R-NIL, web speed up to 30 m/min shown
  • Good adhesion to PC and PET substrates
  • Excellent dry etch stability for pattern transfer processes
  • Residue-free removable with oxygen plasma

Applications

  • Etch mask for pattern transfer processes (dry and wet etching)
  • Application of  nanostructures on polymer foils
  • Fabrication of nanostructures for
    • Nano-optical devices, SOEs
    • Organic electronics (OLED, OPV, OTFT)
    • Microelectronics
    • LEDs, photonic crystals
