Abstract:
A process for producing a semiconductor device comprising, on a semiconductor substrate, an element-insulating region, an active region, and a gate electrode with a bent portion having a bent-angle &thgr; on the active region, wherein the process comprises the steps of:forming, on a predetermined region of the semiconductor substrate, a mask having such a shape that the circumference of the mask intersects the gate electrode to be formed in a later step and that the line segments of the mask circumference at which the intersection takes place, are approximately parallel to the bisector of the bent-angle &thgr; of the bent portion of the gate electrode; forming, on the area of the semiconductor substrate not covered with the mask, the element-isolating region and thereby determining the active region; removing the mask and then forming the gate electrode having a bent portion; and conducting ion injection using the gate electrode as a mask to form impurity-injected regions in the active region.
