| 摘要 |
A semiconductor device including a gate dielectric film provided on at least one site on a surface of a semiconductor substrate, at least one first gate electrode provided on the gate dielectric film, an inter-electrode dielectric film provided while covering a surface of the first gate electrode, at least partial film thickness of a portion covering a portion other than a corner portion that does not come into contact with the gate dielectric film from among a plurality of corner portions of the first gate electrode being formed to be smaller than at least partial film thickness of a portion covering the corner portion that does not come into contact with the gate dielectric film, and a second gate electrode provided while covering a surface of the inter-electrode dielectric film.
