Abstract
A semiconductor device that has a level shift circuit, an anterior stage circuit, and a posterior stage circuit. The level shift circuit transmits an input signal from a primary potential system to a secondary potential system different from the primary potential system. The anterior stage circuit including a first transistor receives a gate driving signal delivered by the level shift circuit. The posterior stage circuit including a second transistor with the same channel type as that of the first transistor drives a switching element according to the output signal from the first transistor. The threshold voltage of the first transistor is set at a lower value than the threshold voltage of the second transistor.
