Abstract
A semiconductor deviceincludes a semiconductor substrate, insulating interlayer group(first insulating interlayer group), insulating interlayer group(second insulating interlayer group), and seal ring(guard ring). The insulating interlayer groupis formed on the semiconductor substrate. The insulating interlayer groupis formed on the insulating interlayer group. The insulating interlayer groupis formed by an insulating material having a lower dielectric constant than that of the insulating interlayer group. The seal ringis provided so as to surround the circuit forming regions Dand D. The seal ringpenetrates through the interface between the insulating interlayer groupand the insulating interlayer groupand is provided apart from the semiconductor substrate
