Patent ID: 7323746

Claim:
A semiconductor device comprising: a semiconductor substrate having an active region and a device isolation region, the active region including a recess trench, wherein a portion of the recess trench is separated from a sidewall of the device isolation region in a first direction and contacts a sidewall of the device isolation region in a second direction; a gate insulating layer disposed on a surface of the recess trench; a gate electrode disposed on the gate insulating layer and having a recessed portion that at least partially fills the recess trench; and source/drain regions disposed in the active region and separated by the gate electrode, wherein the recess trench comprises first hole tabs, each first hole tab disposed at an end of the recess trench, the first hole tabs disposed in parallel to each other such that a width of the recess trench in the second direction is greater than a width of the source/drain regions in the second direction.
