A planarization process is performed, to remove a portion of the silicon formation layer, a portion of the bottom barrier layer, a portion of the first work function metal layer, and a portion of the top barrier layer. Next, the remaining silicon formation layer is removed completely, and a conductive layer is filled in the gate trench.
