TECHNOLOGY OVERVIEW

Nanoimprint is a lithographic technique to fabricate both micro- and nano-scale patterns via the mechanical deformation of an imprint resist. This technology offers a solution based on the combination of nanoimprinting and conventional injection molding elements—nanoinjection molding—which enables the production of micro- and nano-scale 3D free form products with functionalised surfaces.

This technology allows the fabrication of high-resolution patterns that are suitable for us in optics, consumer products, biomedical and 3D imaging, amongst others. The high-resolution patterns are transferred to thermoplastic material and resin via a mold, and subsequently printed onto polymeric or glass substrates.

As nanoimprint lithography and nanoinjection molding are highly versatile solutions with the ability to impart various functionalities, the technology owner is able to develop customised solutions for various applications, starting from patterning and mold fabrication to pilot-scale production.

TECHNOLOGY FEATURES & SPECIFICATIONS

While nanoimprinting is able to produce patterns and impart functions on 2D products, nanoinjection molding is able to produce patterns onto 3D free-form products, with the following properties:

  • High resolution – 200nm to a few hundred microns
  • Able to impart features such as grating, pillars, and holes
  • Aspect ratio of structures imprinted – up to 3

POTENTIAL APPLICATIONS

Some potential applications of nanoimprinting include (but is not limited to):

  • Micro-arrays for genomics
  • Microfluidic and lab-on-a-chip
  • Anti-reflective
  • Diffractive optics and gratings
  • Surface-relief gratings
  • Virtual and augmented reality
  • Medical equipment and biotech

Benefits

This technology carries the following value proposition:

  • High performance-lower cost ratio
  • Optical structures eliminate the need for sophisticated optical coating
  • Designed for high volume manufacturability
