摘要:
In a ferroelectric capacitor comprising: a lower electrode; a ferroelectric film formed on the lower electrode; and an upper electrode formed on the ferroelectric film, variations in composition profile of elements constituting the ferroelectric film are 50% or lower in the thickness direction of the ferroelectric film, and the polarization switching time of the ferroelectric film is 1 μs or less.
