    摘要: Processes for metal fill in replacement metal gate integration schemes and resultant devices are provided herein. The method includes forming a dummy gate on a semiconductor substrate. The dummy gate includes forming a metal layer between a first material and a second material. The method further includes partially removing the dummy gate to form an opening bounded by a spacer material. The method further includes forming a recess in the spacer material to widen a portion of the opening. The method further includes removing a remaining portion of the dummy gate through the opening to form a trench having the recess forming an upper portion thereof. The method further includes filling the trench and the recess with a replacement metal gate stack.
