摘要:
A method for forming a silicide contact includes depositing a metal layer on silicon such that the metal layer intermixes with the silicon to form an intermixed region on the silicon; removing an unintermixed portion of the metal layer from the intermixed region; and annealing the intermixed region to form a silicide contact on the silicon. A semiconductor device comprising a silicide contact located over a silicon layer of the semiconductor device, the silicide contact comprising nickel (Ni) and silicon (Si) and having Ni amount equivalent to a thickness of about 21 angstroms or less.

摘要:
A method includes forming a silicon germanium layer, forming a layer comprising carbon and silicon on a top surface of the silicon germanium layer, forming a metal layer above the layer comprising carbon and silicon, and performing a thermal treatment to convert at least the layer comprising carbon and silicon to form a metal silicide layer.
