After a bottom electrode film is formed, a ferroelectric film is formed on the bottom electrode film. Then, a heat treatment is performed for the ferroelectric film in an oxidizing atmosphere so as to crystallize the ferroelectric film. Then, a top electrode film is formed on the ferroelectric film. In the heat treatment (i.e., annealing for crystallization), a flow rate of oxidizing gas is set to be in a range of from 10 sccm to 100 sccm.
