Abstract
A semiconductor device comprises: a first semiconductor layer 6 having a first conductivity formed on a substrate having a surface of an insulating material 4; a source region 16a and a drain region 16b, which are formed on the first semiconductor layer so as to be separated from each other and which have a second conductivity different from the first conductivity; a channel region 6 formed on the first semiconductor layer between the source region and the drain region; a gate electrode 10 formed on the channel region a gate sidewall 14 of an insulating material formed on a side of the gate electrode; and a second semiconductor layer 18 having the first conductivity formed on at least the source region. This semiconductor device can effectively suppress the floating-body effect with a simple structure.
