Abstract:
A semiconductor device comprising:a mesa-isolation silicon layer, formed on a first insulating film, in which a channel region and source/drain regions are formed;a gate insulating film formed on said mesa-isolation silicon layer;a conducting layer formed on said gate insulating film;a gate electrode having a first part formed on said first insulating film and a remaining part formed on said conductive layer;a continuous sidewall of an insulating material formed at least on side surfaces of each of said mesa-isolation silicon layer and said gate insulation film wherein said sidewall is formed on a side surface portion of said conducting layer at an end portion of said channel region of said mesa-isolation silicon layer and wherein said side wall extends for a height equal to a distance from a bottom surface of said mesa-isolation silicon layer to a bottom surface of said remaining part of said gate electrode.
