Abstract
The semiconductor device comprises a capacitor including a storage electrode, a capacitor dielectric film formed on the storage electrode, and a plate electrode formed on the capacitor dielectric film, the storage electrodehaving an upper end rounded and having a larger thickness at the upper end than a thickness in the rest region. Whereby electric field concentration on the upper end of the storage electrode can be mitigated, and leakage current increase and dielectric breakdown of the capacitor dielectric film can be precluded.
