Abstract
An integrated circuit includes a complimentary field effect transistor (CFET). The CFET includes a first transistor and a second transistor stacked vertically. A conductive via extends vertically from a first source/drain region of the first transistor past the second transistor. The second transistor includes an asymmetric second source/drain region. The asymmetry of the second source/drain region helps ensure that the second source/drain region does not contact the conductive via.
