摘要:
A method is disclosed for fabricating a semiconductor device having a memory employing a ferroelectric capacitor in which the orientation of the ferroelectric film is controlled. The method for fabricating the semiconductor device includes a first film deposition process for forming a first ferroelectric layer, and a second film deposition process for forming a second ferroelectric layer on the first ferroelectric layer. The film deposition temperature of the first film deposition process is set to at least 600° C.
