A CMOS device with a plurality of PMOS transistors each having a PMOS drain and a plurality of NMOS transistors each having an NMOS drain includes a first interconnect and a second interconnect. The first interconnect is on an interconnect level extending in a length direction to connect the PMOS drains together, and the second interconnect is on the interconnect level extending in the length direction to connect the NMOS drains together. A set of interconnects on at least one additional interconnect level physically couple the first interconnect and the second interconnect to an output of the CMOS device. A third interconnect on the interconnect level extends perpendicular to the length direction and offset from the set of interconnects. The third interconnect is capable of flowing current from the PMOS drains or from the NMOS drains to the output of the CMOS device.

Layout construction for addressing electromigration

A CMOS device with a plurality of PMOS transistors and a plurality of NMOS transistors includes a first interconnect and a second interconnect on an interconnect level connecting a first subset and a second subset of PMOS drains together, respectively. The first and second subsets are different and the first and second interconnect are disconnected on the interconnect level. A third interconnect and a fourth interconnect on the interconnect level connect a first subset and a second subset of the NMOS drains together, respectively. The third interconnect and the fourth interconnect are disconnected on the interconnect level. The first, second, third, fourth interconnects are coupled together through at least one other interconnect level. Additional interconnects on the interconnect level connect the first and third interconnects together, and the second and fourth interconnects together, to provide parallel current paths with a current path through the at least one other interconnect level.
