Shields, P. A. and Allsopp, D. W. E., 2011. Nanoimprint lithography resist profile inversion for lift-off applications. Microelectronic Engineering, 88 (9), pp. 3011-3014.
A method is described in which the tapered features that are inherent to nanoimprint lithography are inverted to allow successful lift-off. A mold of the relief is created by in-filling the imprinted resist with hydrogen silsesquioxane (HSQ) before selectively removing the resist with O2 plasma. Nanoscale etch masks have been created by lift-off from the negative HSQ profile and used to create high-aspect-ratio structures in materials that are hard to plasma etch.
