CO-INTEGRATED HIGH PERFORMANCE NANORIBBON TRANSISTORS WITH HIGH VOLTAGE THICK GATE FINFET DEVICES

Abstract:

Embodiments disclosed herein include semiconductor devices and methods of forming such devices. In an embodiment, a semiconductor device comprises a substrate, a first transistor over the substrate, where the first transistor comprises a vertical stack of first semiconductor channels, and a first gate dielectric surrounding each of the first semiconductor channels. The first gate dielectric has a first thickness. In an embodiment, the semiconductor device further comprises a second transistor over the substrate, where the second transistor comprises a second semiconductor channel. The second semiconductor channel comprises pair of sidewalls and a top surface. In an embodiment, a second gate dielectric is over the pair of sidewalls and the top surface of the fin, where the second gate dielectric has a second thickness that is greater than the first thickness.
