Abstract: A method includes providing a substrate with a patterned second layer over a first layer. The second layer includes a second layer opening having a first CD equal to the CD produced by a lithographic system (CDL). CDL is larger than a desired CD (CDD). A third layer is formed to fill the opening, leaving a top surface of the second layer exposed. The second layer is removed to produce a mesa formed by the third layer. The CD of the mesa is equal to about the first CD. The mesa is trimmed to produce a mesa with a second CD equal to about CDD. A fourth layer is formed to cover the first layer, leaving a top of the mesa exposed. The substrate is etched to remove the mesa and a portion of the first layer below the mesa to form an opening in the first layer with CDD.
