NANORIBBON THICK GATE DEVICE WITH HYBRID DIELECTRIC TUNING FOR HIGH BREAKDOWN AND VT MODULATION

Abstract:

Embodiments disclosed herein include semiconductor devices and methods of forming such semiconductor devices. In an embodiment, the semiconductor device comprises a substrate, and a first transistor over the substrate. In an embodiment, the first transistor comprises a first semiconductor channel above the substrate, a first gate dielectric surrounding the first semiconductor channel, and a first gate electrode over the first gate dielectric. In an embodiment, the semiconductor device further comprises a second transistor over the substrate. In an embodiment, the second transistor comprises a second semiconductor channel above the substrate, a second gate dielectric surrounding the second semiconductor channel, where the second gate dielectric is different than the first gate dielectric, and a second gate electrode over the second gate dielectric, where the first gate electrode and the second gate electrode comprise the same material.
