Patent ID: 8652854

Claim:
A manufacturing method of a semiconductor device comprising forming an insulating film over a semiconductor substrate; forming an adhesive layer made of alumina on the insulating film; forming a first conductive film on the adhesive layer; forming a ferroelectric layer, which includes an ABO 3 perovskite structure that contains an Ir element in at least one of an A site and a B site (A=any one of Bi, Pb, Ba, Sr, Ca, Na, K, and a rare earth element, B=any of Ti, Zr, Nb, Ta, W, Mn, Fe, Co, and Cr), on the first conductive film; forming a second conductive film on the ferroelectric layer; forming a capacitor upper electrode by patterning the second conductive film; leaving the ferroelectric layer at least under the upper electrode by patterning the ferroelectric layer; and forming a capacitor lower electrode below the upper electrode by patterning the first conductive film.
