Abstract:
A method includes providing a structure having a first hardmask layer, interposer layer, second hardmask layer and mandrel layer disposed respectively over a dielectric stack. An array of mandrels is patterned into the mandrel layer with a mandrel mask. An ANA trench is patterned into the mandrel layer with a first cut mask. The ANA trench is patterned into the interposer layer with a second cut mask. An organic planarization layer (OPL) is disposed over the structure. The OPL is etched to dispose it only in the ANA trench such that a top surface of the OPL is lower than the second hardmask layer. The structure is etched to form a pattern in a dielectric layer of the dielectric stack to form an array of metal lines in the dielectric layer, a portion of the pattern formed by the ANA trench forms an ANA region within the dielectric layer.

Abstract:
Methods for fabricating integrated circuits are provided. One method includes decomposing a master pattern layout for a semiconductor device layer that includes a target metal line with a target interconnecting via/contact into a first sub-pattern and a second sub-pattern. The target metal line is decomposed into a first line feature pattern that is part of the first sub-pattern and a second line feature pattern that is part of the second sub-pattern such that the first and second line feature patterns have overlapping portions defining a stitch that corresponds to the target interconnecting via/contact. A first photomask is generated that corresponds to the first sub-pattern. A second photomask is generated that corresponds to the second sub-pattern.

Abstract:
A method including providing a semiconductor structure having a dielectric stack, hardmask stack, and mandrel layer disposed thereon. An array of mandrels is patterned into the mandrel layer. Mandrel spacers are formed self-aligned on sidewalls of the mandrels. A gapfill layer is disposed and planarized over the semiconductor structure. Non-mandrel pillars are formed over the planarized gapfill layer. Exposed portions of the gapfill layer are etched to form non-mandrel plugs preserved by the pillars. The pillars are removed to form a pattern, the pattern including the non-mandrel plugs. The pattern is utilized to form an array of alternating mandrel and non-mandrel metal interconnection lines in the dielectric stack. The array includes non-mandrel dielectric structures formed from the non-mandrel plugs.
