Abstract
A semiconductor device includes an active region in a substrate, first to third gate structures crossing the active region and sequentially arranged parallel to each other, a first doped region in the active region between the first and second gate structures and having a first horizontal width and a first depth, and a second doped region in the active region between the second and third gate structures and having a second horizontal width and a second depth. The second horizontal width is larger than the first horizontal width and the second depth is shallower than the first depth. A distance between the first and second gate structures adjacent to each other is smaller than that between the second and third gate structures adjacent to each other. Related fabrication methods are also described.
