Removing substrate pretreatment compositions in nanoimprint lithography
First Claim
1. A nanoimprint lithography method comprising:
- disposing a pretreatment composition on a nanoimprint lithography substrate to form a pretreatment coating on the nanoimprint lithography substrate, wherein the pretreatment composition comprises a polymerizable component;
disposing discrete portions of imprint resist on the pretreatment coating, each discrete portion of the imprint resist covering a target area of the nanoimprint lithography substrate, wherein the imprint resist is a polymerizable composition;
forming a composite polymerizable coating on the nanoimprint lithography substrate as each discrete portion of the imprint resist spreads beyond its target area, wherein the composite polymerizable coating comprises a mixture of the pretreatment composition and the imprint resist;
contacting the composite polymerizable coating with a nanoimprint lithography template;
polymerizing the composite polymerizable coating to yield a composite polymeric layer and an uncured portion of the pretreatment coating on the nanoimprint lithography substrate; and
removing the uncured portion of the pretreatment coating from the nanoimprint lithography substrate.

Abstract
A nanoimprint lithography method to remove uncured pretreatment composition from an imprinted nanoimprint lithography substrate. The method includes disposing a pretreatment composition on a nanoimprint lithography substrate to form a pretreatment coating and disposing discrete portions of imprint resist on the pretreatment coating, each discrete portion of the imprint resist covering a target area of the nanoimprint lithography substrate. A composite polymerizable coating is formed on the nanoimprint lithography substrate as each discrete portion of the imprint resist spreads beyond its target area, and the composite polymerizable coating is contacted with a nanoimprint lithography template. The composite polymerizable coating is polymerized to yield a composite polymeric layer and an uncured portion of the pretreatment coating on the nanoimprint lithography substrate, and the uncured portion of the pretreatment coating is removed from the nanoimprint lithography substrate.
