    摘要: Stable contact hole forming is attained even when an aluminum oxide film is present between layers provided with contact holes. The process comprises the steps of forming a first element layer on a semiconductor substrate; forming a first interlayer insulating film on the first element layer; forming a second element layer on the first interlayer insulating film; forming a second interlayer insulating film on the second element layer; forming a hole resist pattern on the second interlayer insulating film; conducting a first etching for forming of holes by etching the second interlayer insulating film; and conducting a second etching for extending of holes to the first element layer by etching the first interlayer insulating film.

    摘要: A protective film (56) having a water/hydrogen blocking function is formed so as to cover the periphery of a pad electrode (54a) while being electrically isolated from the pad electrode. A material selected in the embodiment for composing the protective film is a highly moisture-proof material having a water/hydrogen blocking function considerably superior to that of the insulating material, such as palladium (Pd) or palladium-containing material, and iridium (Ir) or iridium oxide (IrOx: typically x=2) or an iridium- or iridium oxide-containing material. An FeRAM capable of reliably preventing water/hydrogen from entering inside, and of maintaining high performance of the ferroelectric capacitor structure (30) may be realized only by a simple configuration.
