In a semiconductor device, a first conductive layer (2) is located on a semiconductor substrate (14) through an insulating film (13a) and beneath a first insulating layer (13f). On the first insulating layer (13f) is formed a second conductive layer (8) followed by a second insulating layer (13g), either or both of which are very thin. A third conductive layer (6) is placed on the second insulating layer (13g). A connecting column (16) extends from the third conducting layer (6) through and forming an end contact with the second conductive layer (8) to the first conducting layer (2) and the substrate (14), with a greater portion of the column resting upon the substrate (14). The third conductive layer (6) forms the gate electrode (6b) of a top gate type TFT.
