Abstract: PURPOSE: A method for manufacturing a capacitor of a semiconductor device is provided to solve problems caused by a noble metal, by using polysilicon as upper and lower electrodes of the capacitor. CONSTITUTION: A storage electrode(3) is formed on a substrate(1) by using doped polysilicon. The first Ta2O5 layer(5) is formed on the storage electrode. A BST layer is formed on the first Ta2O5 layer. The second Ta2O5 layer(7) is formed on the BST layer so that a dielectric layer(567) of Ta2O5/BST/Ta2O5 is formed. A plate electrode(9) is formed on the dielectric layer of Ta2O5/BST/Ta2O5 by using doped polysilicon.
