Abstract:
1. A method for forming nanodots during the formation of a semiconductor device, comprising: forming a first patterning material over a base; placing blades of a nanoimprint lithography template within the first patterning material, wherein the blades extend along the base in a first direction; with the blades within the first patterning material, curing the first patterning material; removing the blades from the first patterning material to form a patterned first patterning material; etching the base using the patterned first patterning material as a pattern to form openings in the base; removing the patterned first patterning material from the base; forming a second patterning material over the base and within the openings in the base; placing blades of a nanoimprint lithography template within the second patterning material, wherein the blades extend along the base in a second direction which is generally perpendicular with respect to the first direction; with the blades within the second patterning material, curing the second patterning material; removing the blades from the second patterning material to form a patterned second patterning material; etching the base using the patterned second patterning material as a pattern to form openings in the base; and removing the patterned second patterning material from the base.
