Abstract:
1. A pattern reversal process for self aligned imprint lithography (SAIL) comprising: providing a flexible substrate; depositing at least one layer of thin film material upon the substrate; establishing a pattern upon the layer of thin film material, the pattern providing at least one exposed area and at least one covered area of the thin film layer of material; treating the at least one exposed area to provide at least one etch resistant area within the thin film material, the covered area of thin film material remaining etch susceptible; removing the patterned second layer to expose the treated and untreated areas of the at least one layer of thin film material, the etch susceptible area of thin film material laterally adjacent to the etch resistant area of thin film material; and etching the at least one layer of thin film material to remove the etch susceptible area of material.
