摘要:
In one aspect, a semiconductor substrate is provided having a cell area and a peripheral circuit area, and a mask layer is formed over the cell area and the peripheral circuit area of the semiconductor substrate. A FinFET gate is fabricated by forming a first opening in the mask layer to expose a first gate region in the cell area of the semiconductor substrate, and then forming a FinFET gate electrode in the first opening using a damascene process. A MOSFET gate fabricated by forming a second opening in the mask layer to expose a second gate region in the peripheral circuit area of the semiconductor substrate, and then forming a MOSFET gate electrode in the second opening using a damascene process.
