Abstract:
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.

Claim (Index 17):
A method for fabricating a memory array, the method comprising:\n forming a plurality of memory cells arranged in columns and rows, wherein:\n each of the memory cells includes a FinFET disposed over a doped region of a first dopant type, \n 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; and \n forming a first row of well strap cells, and a second row of well strap cells, wherein:\n the plurality of memory cells is disposed between the first row of well strap cells and the second row of well strap cells, such that each column of memory cells is disposed between a first well strap cell and a second well strap cell, \n the first well strap cell and the second well strap cell each include a fin-based well strap disposed over the doped region of the first type dopant, 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, and the second dopant concentration is greater than the first dopant concentration.
