Disclosed is a method for making a metal gate for a FET, wherein the metal
gate comprises at least some material deposited by electroplating as well
as an FET device comprising a metal gate that is at least partially
plated. Further disclosed is a method for making a metal gate for a FET
wherein the metal gate comprises at least some plated material and the
method comprises the steps of: selecting a substrate having a top surface
and a recessed region; conformally depositing a thin conductive seed
layer on the substrate; and electroplating a filler gate metal on the
seed layer to fill and overfill the recessed region.
