Abstract
A SOI device in which floating body effect is reduced to improve performance. The SOI device including a semiconductor substrate; a first buried insulating film formed on the semiconductor substrate; a first conductivity type silicon layer formed on the first buried insulating film; an active region and a first conductivity type semiconductor layer formed to be isolated on predetermined areas of the first conductivity type silicon layer; second buried insulating films formed to be isolated from one another in the first conductivity type silicon layer to connect the first conductivity type semiconductor layer with the active region through the first conductivity type silicon layer; a gate electrode formed on the active region; impurity region formed in the semiconductor substrate at both sides of the gate electrode; and contact pads formed on the first conductivity type silicon layer.
