  • Semiconductor device and method of manufacturing semiconductor device
    Patent number: 8309414
    Abstract: A first transistor includes a first gate insulating film, a first gate electrode, and a first sidewall. A second transistor includes a second gate insulating film, a second gate electrode, and a second sidewall. A capacitive element is connected to one side of source and drain regions of the second transistor. The first gate insulating film has the same thickness as that of the second gate insulating film, and the first gate electrode has the same thickness of that of the second gate electrode. The width of the second sidewall is larger than the width of the first sidewall.
    Type: Grant
