摘要： A semiconductor device includes a base insulating film on which a silicon fuse, silicon wiring patterns, and a silicon guard ring are formed. The silicon guard ring surrounds the silicon fuse and has silicon cutout parts so as not to contact the silicon wiring patterns. A via guard ring, which has via cutout parts located above the silicon cutout parts, is formed in an interlayer insulating film and on the silicon guard ring. A metal wiring guard ring is formed on the via guard ring and the interlayer insulating film. A silicon nitride film is formed on the interlayer insulating film so as to cover the metal wiring guard ring. An interface between the interlayer insulating film and the metal wiring guard ring at the via cutout parts is covered by the silicon nitride film.

摘要： In an indirect cycle nuclear reactor, a size of the reactor containment vessel is decreased by removing decay heat inside the reactor pressure vessel without using any active component to improve the economic feasibility. A main steam pipe communicating with a heat exchanger of the indirect cycle nuclear reactor is branched in a position upstream of a main steam isolation valve to connect the branched pipe to a heat exchanger in a pressure suppression pool through an isolation valve. A feed water pipe is also branched in a position upstream of an isolation valve to connect the branched pipe to the heat exchanger through the isolation valve. Decay heat is dissipated from the heat exchanger into the pressure suppression pool, and condensed water condensed by heat dissipation is returned to the heat exchanger to cool the inside of the pressure vessel. Heat in the pressure suppression pool is transferred from a condensing type heat exchanger to a heat dissipater outside a containment vessel to be dissipated to the outside of the containment vessel.
