Abstract:
1. An imprint lithography substrate processing tool comprising: a substrate support having a substrate receiving surface adapted to support a substrate having an imprintable material formed thereon during a substrate processing operation; a chucking system to hold a template having a predetermined pattern formed on a portion of the template, the chucking system comprising: (i) a chuck body having first and second opposing sides, the first side being in an opposing relationship to the substrate receiving surface of the substrate support and the first side including a centrally located cavity, a first template support surface surrounding the cavity, a second template support surface surrounding the first template support surface and a recess formed between the first and second template support surfaces; and (ii) a first fluid channel extending through the chuck body to the recess; a pressure control system operatively coupled to apply a vacuum pressure in the recess through the first fluid channel to secure the template to the chucking system; and a source of radiation configured to generate radiation having a predetermined wavelength, the source of radiation and substrate support positioned on opposite sides of the chuck body such that radiation generated by the source is transmitted through the cavity.
