20120187535 | SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING THE SAME - A semiconductor device and a method for manufacturing the same are disclosed. An additional spacer is formed at a lateral surface of an upper part of the bit line so that the distance of insulation films between a storage node and a neighboring storage node contact plug is increased. Accordingly, the distance between the storage node and the neighboring storage node contact is guaranteed and a bridge failure is prevented. | 07-26-2012 |

20130119545 | SEMICONDUCTOR DEVICE AND METHOD FOR FORMING THE SAME - A semiconductor device and a method for forming the same are disclosed, which can protect a polysilicon layer of a bit line contact plug even when a critical dimension (CD) of the bit line is reduced by a fabrication change, thereby preventing defective resistivity caused by a damaged bit line contact plug from being generated. The semiconductor device includes one or more interlayer insulation film patterns formed over a semiconductor substrate, a bit line contact plug formed over the semiconductor substrate between the interlayer insulation films, and located below a top part of the interlayer insulation film pattern, and a bit line formed over the bit line contact plug. | 05-16-2013 |
