    Abstract: The present disclosure provides a method for fabricating an integrated circuit (IC). The method includes receiving an IC design layout defining a semiconductor structure having a via rail extending lengthwise in a first direction and contacting a source contact extending lengthwise in a second direction perpendicular to the first direction. The method further includes identifying the via rail, the source contact, a drain contact being distanced away from the source contact, and a gate structure interposing the source and drain contacts using pattern recognition on the IC design layout. The method further includes determining a position, length, and width of a jog via to be added to the IC design layout. The method further includes adding the jog via having the pre-determined length and width to the IC design layout at the pre-determined position to provide a modified IC design layout and generating a tape-out for fabricating a modified mask.
