Nano-FET Transistor with Alternating Nanostructures and Method of Forming Thereof
Abstract: a method of forming a semiconductor device includes forming a sacrificial layer over a first stack of nanostructures and an isolation region. a dummy gate structure is formed over the first stack of nanostructures, and a first portion of the sacrificial layer. a second portion of the sacrificial layer is removed to expose a sidewall of the first stack of nanostructures adjacent the dummy gate structure. a spacer layer is formed over the dummy gate structure. a first portion of the spacer layer physically contacts the first stack of nanostructures.
