SEMICONDUCTOR DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce the power consumption while suppressing the reduction in operation speed.

SOLUTION: A semiconductor device comprises: a first field effect transistor provided for a substrate having an insulation region on a first semiconductor region and having a second semiconductor region on the insulation region; an insulation layer provided on the substrate; a second field effect transistor provided for one flat surface of the insulation layer and including an oxide semiconductor layer; and a control terminal formed through the same process as a source and a drain of the second field effect transistor and receiving voltage for controlling the threshold voltage of the first field effect transistor.
