Abstract
A method of fabricating a fin field effect transistor (FinFET) includes forming a first fin and a second fin extending upward from a substrate major surface to a first height, forming an insulation layer comprising a top surface extending upward from the substrate major surface to a second height less than the first height, selectively forming a bulbous epitaxial layer covering a portion of each fin, annealing the substrate to convert at least a portion of the bulbous epitaxial layer to silicide and depositing a metal layer at least in the cavity. The first fin and the second fin are adjacent. A portion of the first fin and a portion of the second fin extend beyond the top surface of the insulation layer. The bulbous epitaxial layer defines an hourglass shaped cavity between adjacent fins.
