Nanoimprint electronic functional films for multifunctional metasurface applications

Meta Materials Inc. is developing discrete platform specific proprietary technologies for large-surface-area lithography, allowing the manufacture of nanostructures to be carried out in a cost-effective manner. Each platform employs a massively parallel patterning scheme, designed to be scalable to large areas of either rigid substrate materials and rolls of flexible films. In certain cases we use a phase-shift mask approach called Rolling Mask Lithography and in others, cast NIL printing – all allowing the creation of resonate plasmonic structures with feature sizes down to 50 nm.

In addition, we are also using a first of its kind Plasma deposition technology, which enables high speed coating of any solid material on any type of substrate. We use this metallization step in our roll-to-roll production process for functional films, including security films, which will significantly accelerate line speed and increase capacity. Large scale and efficient metallization coating of ultra-thin substrate with zero defect, is a critical step for volume production of safe reliable lightweight battery materials like separators, requiring hundreds of millions of square meters per year. Additional applications being brought to market include 5G reflection, transparent microwave shielding and windscreen and sensor-window heater functional films, all of which will be reviewed.
