Abstract
A semiconductor device capable of suppressing increase of the capacitance while suppressing a thin-line effect of a silicide film is obtained. This semiconductor device comprises a first silicon layer formed on a semiconductor substrate through a gate insulator film with an upper portion and a lower portion larger in width than a central portion for serving as a gate electrode and a first silicide film formed on the first silicon layer for serving as the gate electrode.
