Abstract:
1. A semiconductor device comprising: a semiconductor substrate formed with a number of semiconductor elements; a first interlayer insulating film formed above said semiconductor substrate and having a first wiring recess; a first copper wiring embedded in the first wiring recess; a second interlayer insulating film having a second wiring recess comprising a wiring trench and a via hole extending in a depth direction from a bottom of said wiring trench, said second interlayer insulating film including a first silicon carbide layer formed on said first copper wiring and said first interlayer insulating film, a silicon oxide film formed directly on the first silicon carbide layer, an organic insulating resin layer formed on the silicone oxide film, and a second silicon carbide layer formed directly on said organic insulating layer, said wiring trench being formed in said second silicon carbide layer and said organic insulating resin layer; and a second copper wiring embedded in the second wiring recess.
