    Abstract: Approaches for multilayer pattern transfer for chemical guides are provided. In a typical embodiment, a device is formed by forming an etch mask layer (e.g., a nitride layer and an oxide layer) over a substrate (e.g., silicon (Si)). An orientation control layer (e.g., a neutral layer) is then formed over the etch mask layer, and an ARC layer (e.g., SiARC) is formed over the orientation control layer. In other embodiments, an organic planarization layer (OPL) and/or a protection layer may also be formed between the ARC layer and the orientation control layer. Regardless, a tapered etch profile/pattern may then be formed through the ARC and/or other layers.

    Abstract: Methods for creating chemical guide patterns by DSA lithography for fabricating an integrated circuit are provided. In one example, an integrated circuit includes forming a bifunctional brush layer of a polymeric material overlying an anti-reflective coating on a semiconductor substrate. The polymeric material has a neutral polymeric block portion and a pinning polymeric block portion that are coupled together. The bifunctional brush layer includes a neutral layer that is formed of the neutral polymeric block portion and a pinning layer that is formed of the pinning polymeric block portion. A portion of the neutral layer or the pinning layer is selectively removed to define a chemical guide pattern. A block copolymer layer is deposited overlying the chemical guide pattern. The block copolymer layer is phase separated to define a nanopattern that is registered to the chemical guide pattern.
