摘要:
A semiconductor device includes a gate electrode having ends that overlap isolation regions, wherein the gate electrode is located over an active region located within a semiconductor substrate. A gate oxide is located between the gate electrode and the active regions, and source/drains are located adjacent the gate electrode and within the active region. An etch stop layer is located over the gate electrode and the gate electrode has at least one electrical contact that extends through the etch stop layer and contacts a portion of the gate electrode that in one embodiment overlies the active region, and in another embodiment is less than one alignment tolerance from the active region.
