RESIDUAL LAYER THICKNESS MODULATION IN NANOIMPRINT LITHOGRAPHY - A simplified explanation of the abstract

This abstract first appeared for US patent application 17932016 titled 'RESIDUAL LAYER THICKNESS MODULATION IN NANOIMPRINT LITHOGRAPHY

Simplified Explanation

The improved nanoimprint lithography process involves controlling the height of the pattern by adjusting the thickness of a residual layer of resin left behind after UV curing and releasing the nanoimprint mold from the resin layer. The thickness of the residual layer can be controlled by the fill factor of the nanoimprint mold or by droplets of resin in the resin layer.

  • Nanoimprint lithography process with controlled height
  • Height control achieved by adjusting thickness of residual resin layer
  • Residual layer thickness controlled by fill factor of nanoimprint mold or resin droplets

Original Abstract Submitted

An improved nanoimprint lithography process is presented in which the height is controlled by the thickness of a residual layer of resin leftover after ultraviolet curing and releasing of a nanoimprint mold from a resin layer. Moreover, the thickness of the residual layer may be controlled by a fill factor of either a nanoimprint mold that transfers its pattern to a resin layer disposed on a substrate, or by droplets of resin in the resin layer.
