US Patent 10157987 Fin-based strap cell structure

Fin-based well straps are disclosed herein for improving performance of memory arrays, such as static random access memory arrays. An exemplary integrated circuit (IC) device includes a FinFET disposed over a doped region of a first type dopant. The FinFET includes a first fin structure doped with a first dopant concentration of the first type dopant and first source/drain features of a second type dopant. The IC device further includes a fin-based well strap disposed over the doped region of the first type dopant. The fin-based well strap connects the doped region to a voltage. The fin-based well strap includes a second fin structure doped with a second dopant concentration of the first type dopant and second source/drain features of the first type dopant. The second dopant concentration is greater than (for example, at least three times greater than) the first dopant concentration.
