Abstract

A FinFET structure includes a substrate, a plurality of stripes, a metal gate and an oxide material. The stripes are on the substrate. The metal gate is on a sidewall and a top surface of one of the stripes. The oxide material is between the metal gate and the stripes. An average roughness of an interface between the metal gate and the oxide material is in a range of from about 0.1 nm to about 0.2 nm.
