Abstract:
1. A semiconductor device, comprising: a capacitor provided on a supporting substrate and including a lower electrode, a dielectric layer, and an upper electrode, said dielectric layer being formed from a ferroelectric material; a first interlayer insulating layer provided so as to cover the capacitor; a first interconnect selectively provided on the first interlayer insulating layer and electrically connected to the capacitor through a first contact hole formed in the first interlayer insulating layer; a second interlayer insulating layer consisting of an interlayer insulating film having a tensile stress provided directly on the first interconnect; and a second interconnect selectively provided directly on the second interlayer insulating layer and electrically connected to the first interconnect through a second contact hole formed in the second interlayer insulating layer.
