Abstract:
1. A semiconductor device comprising: an insulating film which is provided in at least one layer above a substrate and whose relative dielectric constant is 3.4 or less; at least one conductive layer provided in the insulating film; at least one conductive plug which is formed in the insulating film and which is electrically connected to the conductive layer to form a conduction path; at least one reinforcing material which is provided under at least the conductive layer and whose Young's modulus is 30 GPa or more; and a plurality of first reinforcing plugs which are connected to the conductive layer and which are formed in contact with the reinforcing material; wherein the plurality of first reinforcing plugs are arranged within 5 μm from the conductive plug, and an interval between plugs including the respective first reinforcing plugs and the conductive plug is set to about 1 μm or less.
