| 摘要 |
A semiconductor device according to an example of the present invention includes a first semiconductor region of a first conductivity type, a first MIS transistor of a second conductivity type formed in the first semiconductor region, a second semiconductor region of a second conductivity type, and a second MIS transistor of a first conductivity type formed in the second semiconductor region. A first gate insulating layer of the first MIS transistor is thicker than a second gate insulating layer of the second MIS transistor, and a profile of impurities of the first conductivity type in a channel region of the second MIS transistor has peaks.
