Abstract: A semiconductor device includes a MISFET. The semiconductor device also includes a silicon nitride film 12 and a silicon nitride film 10 arranged on the silicon nitride film 12. The silicon nitride film 12 covers at least a portion of an upper part of a source/drain 8 of the MISFET and has a film thickness thinner than a height of a gate electrode 4. The source/drain 8 includes nickel silicide 9 on its boundary to the silicon nitride film 10. The silicon nitride film 10 is a stressed film. A tight adhering property between the silicon nitride film 12 and the surface of the source/drain 8 and that between the silicon nitride film 12 and the silicon nitride film 10 are rendered higher than a tight adhering property which would prevail when the silicon nitride film 10 be made to adhere tightly to the source/drain 8.

Abstract: In a semiconductor circuit device including a first terminal adapted to receive a first voltage and a second terminal adapted to receive a second voltage lower than the first voltage, a capacitive circuit and a short-circuit preventing circuit are provided in series between the first and second terminals. In this case, when the capacitive element is in an insulating (non-conductive) state, the short-circuit preventing circuit is in a conductive state, while, when the capacitive circuit is in a conductive state, the short-circuit preventing circuit is in an insulating state.
