  • Patent number: 9984191
    Abstract: A post placement abutment treatment for cell row design is provided. In an embodiment a first cell and a second cell are placed in a first cell row and a third cell and a fourth cell are placed into a second cell row. After placement vias connecting power and ground rails to the underlying structures are analyzed to determine if any can be merged or else removed completely. By merging and removing the closely placed vias, the physical limitations of photolithography may be by-passed, allowing for smaller structures to be formed.

    Abstract: A mandrel is formed over an active region that includes a first region and a second region. The first region and the second region are reserved for the formation of a source and a drain of a FinFET, respectively. A portion of the mandrel formed over the second region is broken up into a first segment and a second segment separated from the first segment by a gap. Spacers are formed on opposite sides of the mandrel. Using the spacers, fins are defined. The fins protrude upwardly out of the active region. A portion of the second region corresponding to the gap has no fins formed thereover. The source is epitaxially grown on the fins in the first region. At least a portion of the drain is epitaxially grown on the portion of the second region having no fins.
