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 11):
The method of  claim 10 , wherein forming the first etch mask includes depositing a radiation-sensitive material on the substrate, and developing the radiation-sensitive material after photolithographic exposure;\n wherein forming the second etch mask includes depositing a second radiation-sensitive material on the substrate, and developing the second radiation-sensitive material after photolithographic exposure; and further comprising, prior to depositing the second radiation-sensitive material, and subsequent to etching through the uncovered portions of material A and portions of the memorization layer directly underneath the uncovered portions of material A, filling openings in the memorization layer and in the multi-line layer with material C.
