    Abstract: A method includes receiving an integrated circuit design layout that includes first and second layout blocks separated by a first space. The first and second layout blocks include, respectively, first and second line patterns oriented lengthwise in a first direction. The method further includes adding a dummy pattern to the first space, which connects the first and second line patterns. The method further includes outputting a mandrel pattern layout and a cut pattern layout in a computer-readable format. The mandrel pattern layout includes the first and second line patterns and the dummy pattern. The cut pattern layout includes a pattern corresponding to the first space. In embodiments, the method further includes manufacturing a first mask with the mandrel pattern layout and manufacturing a second mask with the cut pattern layout. In embodiments, the method further includes patterning a substrate with the first mask and the second mask.

    Abstract: An overlay mark suitable for use in manufacturing nonplanar circuit devices and a method for forming the overlay mark are disclosed. An exemplary embodiment includes receiving a substrate having an active device region and an overlay region. One or more dielectric layers and a hard mask are formed on the substrate. The hard mask is patterned to form a hard mask layer feature configured to define an overlay mark fin. Spacers are formed on the patterned hard mask layer. The spacers further define the overlay mark fin and an active device fin. The overlay mark fin is cut to form a fin line-end used to define a reference location for overlay metrology. The dielectric layers and the substrate are etched to further define the overlay mark fin.

    Abstract: In a method of manufacturing a semiconductor device, a layout is prepared. The layout includes active region patterns, each of the active region patterns corresponding to one or two fin structures, first fin cut patterns and second fin cut patterns. At least one pattern selected from the group consisting of the first fin cut patterns and the second fin cut patterns has a non-rectangular shape. The layout is modified by adding one or more dummy active region patterns and by changing the at least one pattern to be a rectangular pattern. Base fin structures are formed according to a modified layout including the active region patterns and the dummy active region patterns. Part of the base fin structures is removed according to one of a modified layout of the first fin cut patterns and a modified layout of the second fin cut patterns.
