发明名称 Semiconductor device and method for manufacturing the same
摘要 A ferroelectric capacitor is formed over a semiconductor substrate (10), and thereafter, interlayer insulating films (48, 50, 52) covering the ferroelectric capacitor are formed. Next, a contact hole (54) reaching a top electrode (40) is formed in the interlayer insulating films (48, 50, 52). Next, a wiring (58) electrically connected to the top electrode (40) through the contact hole (54) is formed on the interlayer insulating films (48, 50, 52). At the time of forming the top electrode (40), conductive oxide films (40a, 40b) are formed, and then a cap film (40c) composed of a noble metal exhibiting less catalytic action than Pt and having a thickness of 150 nm or less is formed on the conductive oxide films (40a, 40b).
