APPARATUS AND METHOD OF FORMING METAL OXIDE SEMICONDUCTOR FIELD-EFFECT TRANSISTOR WITH ATOMIC LAYER DEPOSITED GATE DIELECTRIC

摘要

A method for forming a metal oxide semiconductor field-effect transistor (MOSFET) includes forming a III-V compound semiconductor on a substrate with the III-V compound semiconductor being doped with a first dopant type. The method further includes doping a first and second region of the III-V compound semiconductor with a second dopant type to form a drain and a source of the MOSFET. The method further includes forming a gate dielectric on the III-V compound semiconductor through atomic layer deposition. The method further includes applying a metal onto the dielectric to form a gate of the MOSFET. A MOSFET is also disclosed herein.
