Patent ID: 7029984

Claim:
A method for fabricating a semiconductor device including a ferroelectric capacitor, the method comprising: a lower electrode forming step for forming a lower electrode of the ferroelectric capacitor; a first film deposition step for forming a first ferroelectric film primarily having a (111) orientation on the lower electrode through a vapor deposition process using an organic metal source; a second film deposition step for forming a second ferroelectric film primarily having a (111) orientation on the first ferroelectric film through a vapor deposition process using the organic metal source; and an upper electrode forming step for forming an upper electrode on the second ferroelectric film; wherein the first ferroelectric film and the second ferroelectric film include at least one of Pb (Zr x , Ti 1-x )O 3 and PbTiO 3 ; and a film deposition temperature of the first film deposition step is 600–650° C.
