Abstract
A semiconductor device includes a first device isolation insulating film defining a first region, a first conductive layer of a first conductivity type formed in the first region, a semiconductor layer formed above the semiconductor substrate and including a second conductive layer of the first conductivity type connected to the first conductive layer and a third conductive layer of the first conductivity type connected to the first conductive layer, a second device isolation insulating film formed in the semiconductor layer and isolating the second conductive layer and the third conductive layer from each other, a gate insulating film formed above the second conductive layer, and a gate electrode formed above the gate insulating film and electrically connected to the first conductive layer via the third conductive layer.
