Abstract

Ultraviolet-nanoimprint lithography (UV-NIL) is a promising nanoimprint method for cost-effectively defining nanometer scale structures at room temperature and low pressure. Nanostamp fabrication technology is a key technology for UV-NIL because fabricating a high resolution nanostamp is the first step for defining high resolution nanostructures in a substrate. We used quartz as an UV transparent stamp material for the UVNIL. A $5{\times}5{\times}0.09$ inch stamp was fabricated using the quartz etch process in which Cr film was used as a hard mask for transferring nanostructures into the quartz. In this paper, we describe the quartz etching process and discuss the results including SEM images.
