Abstract:
1. A method of patterning a substrate, comprising: forming spaced first features over a substrate, individual of the spaced first features comprising sidewall portions of different composition than material that is laterally between the sidewall portions; providing a mixture of immiscible materials between the spaced first features; laterally separating at least two of the immiscible materials along at least one elevation between adjacent spaced first features, the laterally separating forming a laterally intermediate region comprising one of the immiscible materials between two laterally outer regions comprising another of the immiscible materials along the one elevation; and removing the laterally outer regions and removing the material of the spaced first features between the sidewall portions to form spaced second features over the substrate, the spaced second features comprising a combination of the different composition material of the sidewall portions and the one immiscible material of the laterally intermediate regions.
