Abstract:
1. A method for forming a patterned layer on a substrate by means of an imprint process comprising the steps of: providing a single patterning means; providing a first layer on a surface of said substrate; simultaneously forming patterns of recesses in the first layer by imprinting said first layer with said patterning means, wherein said patterns of recesses includes a first pattern of recesses and a second pattern of recesses that are wider than said recesses of said first pattern; curing said first layer; performing a first surface treatment onto said first layer to make a surface of the first layer hydrophilic; performing a second surface treatment onto a selected subarea of the surface of said first layer to make said subarea hydrophobic, said subarea including surface portions between said recesses of said first pattern and excluding said recesses of said first pattern; and depositing a first conducting pattern material into said recesses of said first pattern and a second conducting pattern material that is different from said first conducting pattern material into said recesses of said second pattern, wherein the first and second conducting pattern materials form a single, cohesive electrode and wherein the chemical composition of said electrode in said recesses of said first pattern is different from the chemical composition of said electrode in said recesses of said second pattern.
