Abstract
In methods for fabricating MOS transistors with notched gate electrodes, a notched gate electrode may be readily fabricated using a damascene process for filling a stair-shaped opening formed in a multi-layered insulation layer. In this manner, the width and a height of the notch region of the gate electrode may be readily adjusted and controlled.
