Abstract: An electronic system device comprises a power generation device generating a power supply voltage, a substrate bias generation circuit connected to the power generation device, a memory circuit, a monitor circuit, and a capacitor connected to the substrate bias generation circuit via a switch. The substrate bias generation circuit generates a substrate bias voltage from the power supply voltage and supplies charges based on the substrate bias voltage to the capacitor while the switch is ON-state. While the switch is OFF-state, the capacitor stores the accumulated charges based on the substrate bias voltage. While the switch is ON-state, the substrate bias generation circuit adds based on the substrate bias voltage to charge that was held, and states the back bias voltage. The substrate bias generation circuit supplies the back bias voltage to memory circuit.

Abstract: An electronic system device includes a semiconductor device and a power generating device for generating a power supply voltage. The semiconductor device includes a control circuit coupled with the power generating device via a power supply node, and a substrate-biased control circuit coupled with the control circuit. The electronic system device includes a DC-DC converter, and a switch arranged between the power supply nodes and the DC-DC converter. The control circuit sets the switch to an ON state after receiving the power supply voltage. The DC-DC converter receives the power supply voltage after the switch is controlled to the ON state. The substrate bias control circuit supplies a substrate bias voltage to the control circuit before the DC-DC converter receives the power supply voltage.

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.
