Abstract:
1. A method of forming a pattern on a substrate, the pattern comprising a repeating pattern region and a pattern-interrupting region adjacent to the repeating pattern region, comprising: forming a pattern-interrupting region mask elevationally over underlying substrate material, the pattern-interrupting region mask comprising masking material, the masking material of the pattern-interrupting region mask forming a raised masking feature within the pattern-interrupting region, none of the masking material of the pattern-interrupting region mask being within the repeating pattern region; forming a repeating pattern region mask elevationally over the pattern-interrupting region mask, the repeating pattern region mask comprising multiple raised masking features that are elevationally over the raised masking feature of the pattern-interrupting region mask within the pattern interrupting region and multiple raised masking features that are not elevationally over the raised masking feature of the pattern-interrupting region mask within a repeating pattern region, the repeating pattern region being different from and everywhere laterally of the pattern-interrupting region, the repeating pattern region and the pattern-interrupting region being immediately laterally adjacent one another; and using the pattern-interrupting region mask and the repeating pattern region mask as a combination mask in forming the pattern into the underlying substrate material on which the combination mask is received.
