Patent 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.
