Abstract:
A semiconductor device includes a first metal wiring layer, an interlayer insulating layer formed over the first metal layer, a second metal wiring structure embedded in the interlayer dielectric layer and connected to the first metal wiring layer, and an etch-stop layer disposed between the first metal wiring and the first interlayer dielectric layer. The etch-stop layer includes one or more sub-layers. The etch-stop layer includes a first sub-layer made of an aluminum-based insulating material, hafnium oxide, zirconium oxide or titanium oxide.

Claim (Index 14):
The method of  claim 8 , wherein the first sub-layer is made of at last one from the group consisting of aluminum oxy-carbide and aluminum oxy-nitride having a non-uniform nitrogen concentration in a thickness direction, aluminum oxy-carbide having a non-uniform carbon concentration in the thickness direction, hafnium oxide, zirconium oxide and titanium oxide.
