    摘要： A method to generate chemo-epitaxy masks includes receiving a device pattern comprising a plurality of device geometries, wherein the device pattern conforms to chemo-epitaxy constraints, enlarging the device geometries along a width of the device geometries to provide enlarged device geometries, and using the enlarged device geometries to generate at least one chemo-epitaxy mask corresponding to the device pattern. The at least one chemo-epitaxy mask may include a neutral hard mask and one or more cut masks. The method may also include bridging device geometries that are within a selected distance along a length of the device geometries and merging device geometries that overlap. The method may also include filling break regions between the device geometries with a neutral fill pattern. A corresponding computer program product and computer system are also disclosed herein.

    摘要： A design layout including shapes of target areas for forming semiconductor fins employing directed self-assembly can be decomposed into guiding patterns and cut patterns. The lengthwise edges of the shapes of target areas are adjusted. Widthwise edges of the adjusted shapes are extended outward to generate diffusion shapes. Guiding pattern shapes are then generated employing the diffusion shapes. Taper edges are adjusted based on process bias of a photoresist material to be subsequently employed. Optionally, a portion of a guiding pattern shape between diffusion shapes may be removed as a connection shape. The guiding pattern shapes can define at least one guiding pattern mask for lithographic pattern of guiding pattern shapes, and cut shapes can be derived from the diffusion shapes and the guiding pattern shapes. The guiding pattern shapes and the cut shapes may be adjusted to accommodate effects at device cell edges and at device macro edges.
