Patent ID: 8741781

Claim:
A method of forming a semiconductor construction, comprising: forming a plurality of features over a base, each feature having a pair of opposing sidewalls with one of the sidewalls being a first type and the other being a second type; the features being spaced from one another by gaps; some of the gaps being first type gaps between first type sidewalls and others of the gaps being second type gaps between second type sidewalls; forming masking material over the features; the masking material selectively filling the first type gaps relative to the second type gaps; masking material outside of the first type gaps being excess masking material; the second gaps containing only empty spaces after forming the masking material, and the masking material extending over and entirely across such empty spaces; removing the excess masking material to leave a patterned mask comprising the features in combination with the masking material in the first type gaps; and transferring a pattern from the patterned mask into one or more materials of the base.
