  • Nanoimprint lithography(NIL) is an emerging technology enabling cost-effective and high-throughput nanofabrication. Among NILs, significant efforts from both academia and industry have been put in UV NIL research and development because of its ability to pattern at room temperature and at low pressure. In UV NIL, there may be in-line set-up error of the stamp and the substrate. To compensate this error, the dummy blocks are put on the stamp and pressurized uniformly. Contact problems between the stamp and the photoresist layer on the substrate are often happened, which results in the non-uniform residual layer In this paper, the pressurization method on the dummy block is investigated by the finite element method. A new method is recommended and evaluated far the uniform stamp deformation.
