    摘要: In a preferred aspect, methods are provided that comprise a) providing a semiconductor substrate comprising a patterned mask over a layer to be patterned; b) applying a layer of a first composition over the mask, wherein the composition comprises a polymer and the layer is coated on a sidewall of the mask; c) applying a layer of a second composition over the semiconductor substrate in a volume adjacent the coated sidewall of the mask; and d) removing the first composition from the sidewall of the mask, thereby exposing the layer to be patterned and forming a gap between the mask sidewall and the second composition layer to provide a relief image. The methods find particular applicability in semiconductor device manufacture.
