Abstract:
1. A method of patterning a plurality of substrates, comprising: providing an imprint template having a plurality of spaced features; imprinting a first substrate with the imprint template effective to form a plurality of recesses into the first substrate from the spaced features; after imprinting the first substrate, removing elevationally outermost portions of the spaced features by anisotropically etching through elevationally outermost surfaces of the spaced features without laterally etching into lateral side surfaces of the spaced features below the removed elevationally outermost portions effective to reduce elevation of the spaced features without reducing width of the spaced features; and after the removing, imprinting a second substrate with the imprint template using the elevation-reduced spaced features effective to form a plurality of recesses into the second substrate from the elevation-reduced spaced features.
