    摘要: A method of aligning a substrate and an imprint template is disclosed. The method includes directing an alignment radiation beam towards an imprint template alignment mark and an adjacent substrate alignment mark, the imprint template alignment mark and the substrate alignment mark each including a grating which extends in a first direction and a grating which extends in a second direction, providing relative movement between the imprint template and the substrate in the first direction and in the second direction, using an intensity detector to detect the intensity of alignment radiation redirected in the zero-order direction by the imprint template alignment mark and the substrate alignment mark during the relative movement in the first direction and in the second direction, and determining an aligned position of the imprint template alignment mark and the substrate alignment mark based upon the detected intensity.

    摘要: A method of lithography on a substrate uses a self-assembled polymer (SAP) layer deposited on the substrate, with first and second domains arranged in a pattern across the layer. A planarization layer is formed over the SAP and a development etch applied to substantially remove a portion of the planarization layer over the second domain leaving a cap of the planarization layer substantially covering the first domain. The uncapped second domain is then removed from the surface by a breakthrough etch leaving the capped first domain as a pattern feature on the surface. A transfer etch may then be used to transfer the pattern feature to the substrate using the capped first domain. The capping allows the second domain to be removed, e.g., without excessive loss of lateral feature width for the remaining first domain, even when the difference in etch resistance between the first and second domains is small.
