Abstract
A method of fabricating a static random-access memory (SRAM) device includes forming a sacrificial material and replacing the sacrificial material with a metal to form a cross-couple contact on a metal gate stack. A portion of the metal gate stack directly contacts each of a sidewall and an endwall of the cross-couple contact.
