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.
