Abstract:
The present disclosure, in some embodiments, relates to an integrated chip. The integrated chip includes a source region and a drain region separated by a channel region within a substrate. A middle-end-of-the-line (MEOL) structure is over the drain region and a gate structure is over the channel region. The MEOL structure is vertically disposed between the drain region and a plane extending along an upper surface of the gate structure. A first interconnect wire is connected to the MEOL structure by a first conductive contact that is directly over the drain region and that extends between the first interconnect wire and the MEOL structure. A conductive strap is located over the first interconnect wire. The conductive strap connects the first interconnect wire to a power rail having a larger width than the first interconnect wire.
