Apparatus for aligning a first article relative to a second article
Abstract:
A method and apparatus is described for aligning a first article relative to a second article, for example for aligning a nanoimprint template with a semiconductor wafer. The method comprises the steps of: providing said second article with at least one flexible structure fixed relative thereto at least one point, providing a first article having at least one surface relief marking thereon, providing a detector for measuring an interaction of the flexible structure with the surface relief marking and generating detector signals relating to said interaction, identifying with the help of the detector signals the position of the flexible structure and thus of the second article with respect to the surface relief marking and generating relative movement between the first and second articles to achieve a desired alignment between the first and second articles defined by the surface relief marking. In this method and apparatus the flexible structure is brought into contact with the surface relief marking.
