Abstract

A semiconductor device includes a first-type transistor, a second-type transistor, and a t-shaped backbone. The first-type transistor includes a first-type source/drain and the second-type transistor includes a second-type source/drain. The t-shaped backbone includes a wall and a sub-wall. The wall separates the first-type transistor and the second-type source/drain. The sub-wall extends from the wall and into the second-type source/drain.
