    摘要: Methods are provided for fabricating a semiconductor device. One method comprises providing a first pattern having a first polygon, the first polygon having a first tonality and having a first side and a second side, the first side adjacent to a second polygon having a second tonality, and the second side adjacent to a third polygon having the second tonality, and forming a second pattern by reversing the tonality of the first pattern. The method further comprises forming a third pattern from the second pattern by converting the second polygon from the first tonality to the second tonality forming a fourth pattern from the second pattern by converting the third polygon from the first tonality to the second tonality forming a fifth pattern by reversing the tonality of the third pattern, and forming a sixth pattern by reversing the tonality of the fourth pattern.

    摘要: Accurate ultrafine patterns are formed using a multiple exposure technique comprising implementing an OPC procedure to form an exposure reticle to compensate for distortion of an overlying resist pattern caused by an underlying resist pattern. Embodiments include forming a first resist pattern in a first resist layer over a target layer using a first exposure reticle, forming a second exposure reticle by an OPC technique to compensate for distortion of a second resist pattern caused by the underlying first resist pattern, depositing a second resist layer on the first resist pattern, forming the second resist pattern in the second resist layer using the second exposure reticle, the first and second resist patterns constituting a final resist mask, and forming a pattern in the target layer using the final resist mask.
