Patent ID: 10488753

Abstract:
A nanoimprint lithography method includes contacting a composite polymerizable coating formed from a pretreatment composition and an imprint resist with a nanoimprint lithography template defining recesses. The composite polymerizable coating is polymerized to yield a composite polymeric layer defining a pre-etch plurality of protrusions corresponding to the recesses of the nanoimprint lithography template. The nanoimprint lithography template is separated from the composite polymeric layer. At least one of the pre-etch plurality of protrusions corresponds to a boundary between two of the discrete portions of the imprint resist, and the pre-etch plurality of protrusions have a variation in pre-etch height of ±10% of a pre-etch average height. The pre-etch plurality of protrusions is etched to yield a post-etch plurality of protrusions having a variation in post-etch height of ±10% of a post-etch average height, and the pre-etch average height exceeds the post-etch average height.
