Abstract

See full text

A semiconductor device includes a substrate, a first gate structure, a second gate structure, a third gate structure, and a first source/drain region. The first, second, and third gate structures are above the substrate and arranged in a first direction. The first, second, and third gate structures extend in a second direction different from the first direction, and the second gate structure is between the first and third gate structures. The first source/drain region is between the first and third gate structures, and the first source/drain region is at one end of the second gate structure.
