  • Patent number: 10163724
    Abstract: An integrated circuit device and method for manufacturing the integrated circuit device is disclosed. The disclosed method provides improved protection for the bottom portion of the gate structure. In some embodiments, the method achieves improved protection for gate structure bottom by forming a recess on either side of the gate structure and placing spacers on the side walls of the gate structure, so that the spacers protect the portion of the gate structure below the gate dielectric layer.
