20100001340	SEMICONDUCTOR DEVICE AND METHOD FOR FABRICATING THE SAME - A semiconductor device includes a step-type recess pattern formed in a substrate, a gate electrode buried in the recess pattern and having a gap disposed between the gate electrode and upper sidewalls of the recess pattern, an insulation layer filling the gap, and a source and drain region formed in a portion of the substrate at two sides of the recess pattern. The semiconductor device is able to secure a required data retention time by suppressing the increase of leakage current caused by the reduction of a design rule.	01-07-2010
20100258861	SEMICONDUCTOR DEVICE WITH RECESS GATE AND METHOD FOR FABRICATING THE SAME - A semiconductor device includes a substrate with a recess pattern, a gate electrode filling the recess pattern, a threshold voltage adjusting layer formed in the substrate under the recess pattern, a source/drain region formed in the substrate on both sides of the gate electrode and a gate insulation layer, with the recess pattern being disposed between the gate electrode and the substrate, wherein the thickness of the gate insulation layer formed in a region adjacent to the source/drain region is greater than the thickness of the gate insulation layer formed in a region adjacent to the threshold voltage adjusting layer.	10-14-2010
