Abstract:
A composite patterning technique may include two lithography processes. A first lithography process may use interference lithography to form an interference pattern of lines of substantially equal width and spaces on a photoresist. A second lithography process may use one or more non-interference lithography techniques, such as optical lithography, imprint lithography and electron-beam lithography, to break continuity of the patterned lines and form desired integrated circuit features.
Abstract:
Systems and techniques for printing substrates. In one implementation, a method includes patterning a substrate with a substantially arbitrary arrangement of features by introducing irregularity into a repeating array of features.

Abstract:
A composite patterning technique may include three lithography processes. A first lithography process forms a periodic pattern of alternating continuous lines of substantially equal width and spaces on a first photoresist. A second lithography process uses a non-interference lithography technique to break continuity of the patterned lines and form portions of desired integrated circuit features. The first photoresist may be developed. A second photoresist is formed over the first photoresist. A third lithography process uses a non-interference lithography technique to expose a pattern on the second photoresist and form remaining desired features of an integrated circuit pattern.
