SEMICONDUCTOR DEVICE AND METHOD FOR CONTROLLING MOS TRANSISTOR

摘要

[Problem] To provide: a semiconductor device able to suppress leak current in an MOS transistor; and a method for controlling an MOS transistor. [Solution] The semiconductor device is equipped with an MOS transistor and a voltage imposition unit that is for imposing onto the substrate of the MOS transistor a voltage for controlling the MOS transistor threshold to the lower direction when the MOS transistor is off.
