Abstract
A device is disclosed. The cell block includes a pin disposed at a Nth metal layer in a cell layout. The first metal interconnect is disposed at a (N+1)th metal layer above the Nth metal layer and stacked over the pin, and electrically coupled to the pin. The second interconnects are disposed at a (N+2)th metal layer and stacked over the first metal interconnect, and parallel to each other. The second metal interconnects are electrically coupled to the first metal interconnect, and forming an equivalent tapping point of the pin of the cell block. The equivalent tapping point and the pin are vertically overlapped with each other, and fabrication of the device is initiated after a DRC or a SEM simulation test is passed. A first width of at least one first metal interconnect is different from a second width of one of the plurality of second metal interconnects.
