    摘要: The disclosure relates to a fin field effect transistor (FinFET). An exemplary structure for a FinFET comprises a substrate comprising a major surface; a first fin and a second fin extending upward from the substrate major surface to a first height; an insulation layer comprising a top surface extending upward from the substrate major surface to a second height less than the first height, whereby portions of the fins extend beyond the top surface of the insulation layer; each fin covered by a bulbous epitaxial layer defining an hourglass shaped cavity between adjacent fins, the cavity comprising upper and lower portions, wherein the epitaxial layer bordering the lower portion of the cavity is converted to silicide.

    摘要: The present disclosure provides a method of fabricating a semiconductor device. The method includes forming a gate dielectric over a semiconductor substrate, forming a capping layer over or under the gate dielectric, forming a metal layer over the capping layer, the metal layer having a first work function, treating a portion of the metal layer such that a work function of the portion of the metal layer changes from the first work function to a second work function, and forming a first metal gate from the untreated portion of the metal layer having the first work function and forming a second metal gate from the treated portion of the metal layer having the second work function.
