Abstract
A process for fabricating a semiconductor device comprising the steps of forming a gate insulation layer on a first conductive type semiconductor substrate, forming a polycrystalline silicon layer on the gate insulation layer, and selectively removing the polycrystalline silicon layer to form a gate electrode and a direct contact electrode. The process also includes a step of forming a photoresist mask masking the direct contact electrode at least at the side opposing the gate electrode, and performing ion implantation of a second conductive type impurity for forming an impurity diffused layer at both sides of the gate electrode. The direct contact electrode and the impurity diffused layer are electrically connected by a conductive layer covering the surface of one of the impurity diffused layer and the side surface of the direct contact electrode.
