Abstract:
Techniques disclosed herein, provide a method and fabrication structure for accurately increasing feature density for creating high-resolution features and also for cutting on pitch of sub-resolution features. Techniques include using multiple materials having different etch characteristics to selectively etch features and create cuts or blocks where specified. A multiline layer is formed of three or more different materials that provide differing etch characteristics. Etch masks, including interwoven etch masks, are used to selectively etch cuts within selected, exposed materials. Structures can then be cut and formed. Forming structures and cuts can be recorded in a memorization layer, which can also be used as an etch mask.

Claim (Index 2):
The method of  claim 1 , further comprising: etching through material B and portions of the memorization layer directly underneath material B while the multi-line layer is uncovered.
