Abstract
Integrated circuits that have a FinFET and methods of fabricating the integrated circuits are provided herein. In an embodiment, a method of fabricating an integrated circuit having a FinFET includes providing a substrate comprising fins. The fins include semiconductor material. A first metal oxide layer is formed over sidewall surfaces of the fins. The first metal oxide layer includes a first metal oxide. The first metal oxide layer is recessed to a depth below a top surface of the fins to form a recessed first metal oxide layer. The top surface and sidewall surfaces of the fins at a top portion of the fins are free from the first metal oxide layer. A gate electrode structure is formed over the top surface and sidewall surfaces of the fins at the top portion of the fins. The recessed first metal oxide layer is recessed beneath the gate electrode structure.
