    摘要: Some embodiments include methods of patterning materials. A mass may be formed over a material, and a first mask may be formed over the mass. First spacers may be formed along features of the first mask, and then the first mask may be removed to leave a second mask corresponding to the first spacers. A pattern of the second mask may be partially transferred into the mass to form an upper portion of the mass into a third mask. The first spacers may be removed from over the third mask, and then second spacers be formed along features of the third mask. The second spacers are a fourth mask. A pattern of the fourth mask may be transferred into a bottom portion of the mass, and then the bottom portion may be used as a mask during processing of the underlying material.
