Abstract:
1. A method of making an imprint template, comprising: using a master imprint template to imprint a pattern into a layer of imprintable medium on a transfer layer on a substrate; polymerizing the patterned imprintable medium by exposing it to actinic radiation to form a patterned imprintable medium polymer layer; providing a silicon rich layer on the patterned imprintable medium polymer layer; polymerizing the silicon rich layer by exposing it to actinic radiation; and etching the resulting polymerized silicon rich layer, the patterned imprintable medium polymer layer, the transfer layer and the substrate such that the imprinted pattern is transferred to the substrate, the substrate thereby becoming an imprint template bearing a pattern which corresponds to a pattern on the master imprint template.
